Defender Vacation 01 - Small battery for your purposes
3 Losev D. 06-07-2018
Defender Vacation 01
Advantages:
Size - you can put it in your shirt pocket. Weight - no more than a passport in a cover. Charges iPhone 7 to 80%. A good backup source of energy.
Flaws:
Lace. It's very short. As a result, the device will hang on its cord in your pocket, reducing both its resource and the phone connector. The conclusion is to either charge in your hand or when the phone is lying on the table. Alternatively, in a bag, on the side.
Defender Vacation 01 - good battery for emergency charging.
5 Olga Vladimirovna L. 14-01-2018
Device owner rating: Defender Vacation 01
Advantages:
Very small, flat, light - just the thing with you. Charges samsung galaxy s6 edge by 60% (total battery capacity is 2600 mAh, so it actually gives about 1600 mAh). Accordingly, it is good for emergency charging, just reach the outlet. But you couldn’t expect more with such a low weight and compactness.
Flaws:
The iPhone adapter is held in the socket only by the charging cable, so it falls out when used. Because I don't need it - I just took it out...
Performance comparison and test results
To help you make an informed choice, the power bank was tested at NICS Computer Supermarket on 10/26/2019. The test results are clearly displayed in a diagram and two tables.
The diagram shows the test results for the selected article (highlighted in red) and 9 more products of similar price. Percentages indicate an approach to the maximum recorded results. That is, if your choice fell on a product with an indicator of 50%, this means that there is an analogue that is 2 times faster (with an indicator of 100%), but, of course, at a completely different price.
The diagram is followed by a table with similar indicators for 10 champion products in their category, in the form of a TOP10 rating.
Using this table, it is easy to determine the place of an external battery in the overall “table of ranks”, as well as estimate how expensive it will be to try to improve performance. The selected product is also highlighted in red.
The last plate is simply a list of test results. From these, a percentage ranking is calculated, which was used in the first two reports. By clicking on the name of the test, you can go to a summary table with indicators for all products in the category, including those that are currently out of stock.
Comparisons only use products that are currently in stock.
Any person at least once in his life has encountered an urgently needed battery that was discharged at the wrong time. electronic device, and many of us experience such trouble regularly.
The way to solve the problem is simple - you just need to get a compact external battery, recharge it in a timely manner and don’t forget it at home when going on business. We offer you a rating of the best external batteries of 2018 - the first half of 2019, based on reviews from experts and ordinary buyers. Just don’t forget - to choose the best external battery, you need to realistically assess your needs and choose a device with optimal capacity. As a first approximation, its value should be twice as high as the corresponding battery indicator of the gadget that is supposed to be charged most often.
External battery capacity - what does it mean?
When indicating the rated capacity for their external batteries, manufacturers write the truth, but not the whole truth. For example, the 13,000 mAh declared for the Canyon CNE-CPB130 actually has a built-in battery. Only you can fully charge a smartphone with a 4,000 mAh battery with such a power bank only twice. The fact is that the nominal capacity here means the energy reserve accumulated by the device’s battery at its operating voltage. In this case, it is approximately 3.7 volts, which is noticeably lower than the value defined by the USB specification. And then charge mobile equipment It is necessary through this interface, the internal voltage is converted to standard 5 V with a proportional decrease in the available capacity. In addition, part of the energy is spent on the operation of the corresponding electronic circuit. For reference, current external batteries use lithium-ion (3.6-3.7 V) or lithium-polymer (3.85 V) batteries, and the efficiency of the converters ranges from 0.9 to 0.95.
Thus, knowing the “capacity” of the batteries of a power bank and a smartphone, it is easy to calculate how many times you can charge the second device with the first device. To do this, the nameplate value of the capacity of the external battery must be multiplied by the operating voltage of its own battery (if the type is unknown, take 3.6 V), divide by 5 volts of the USB interface, and multiply the result by the efficiency (set to 0.9). As a result, we will get the useful capacity of the device, which can be used when charging.
To complete our example, we have (13000 * 3.7 / 5) * 0.9 = 8658 mAh, which is enough for two full charges, say Xiaomi Redmi 4X with its 4,100 mAh battery. And there will still be a little left “in reserve.”
I welcome everyone who stopped by. The review will focus, as you probably already guessed, on the interesting thin PB Pineng PN-951, with a capacity of 10000mAh. Interesting features include a built-in cable with a Lightning adapter for Apple gadgets, a high output current of 2.5A (short-term 3A), as well as forced activation of electronics with waves. As I understand it, this is a continuation of the PN-963 line, which I made a long time ago, but unlike its predecessor, this model lost its digital display and acquired standard LED indicators. For anyone interested in how the new product performed, you are welcome under the cat.

Equipment:
PB Pineng PN-951 10000mah
- charging cable USB -> microUSB, length 55cm
- instructions in English and Chinese 
The box is quite colorful and compact, ideal as a gift: 
On the back there are the main specifications: 
Inside there is a plastic protective box, under which the cable and instructions are placed: 
The instructions are quite detailed, in English: 
Appearance:
The PB is made in the form of a rectangular monoblock with slightly rounded edges. The case is made of impact-resistant plastic with some knurling, very pleasant to the touch. By the way, the knurling here is absolutely the same as in the PN-963 model: 
The case is quite durable, which is not as easy to scratch as it might seem at first glance. In addition, the diamond-shaped knurling shimmers in a unique way and creates the impression of an unusual and, I would even say, far from budget device. Of course, the aluminum body looks more solid, but the pluses plastic case This may include the reduced weight of the device and the inability to scratch nearby objects, which could be the cases/displays of smartphones or tablets. In addition, the aluminum case has a habit of getting scratched after some time by keys, connectors or other hard objects.
The microUSB charging port is located on the side of the device: 
The top panel also contains four LED indicators of remaining capacity, which are activated when a load is connected or when the device is shaken. In my opinion, this is a controversial decision; it would be more reasonable to leave the mechanical button that was present in previous models: 
The main highlight of the device is the built-in micro USB cable and an 8-pin Lightning adapter, allowing you to do without an external cable when recharging various gadgets: 
As you can see, the Lightning adapter is hidden inside the case, along with a full-size USB port: 
The general diagram of the device looks like this: 
On the bottom panel there is helpful information according to the parameters, where the manufacturer clearly indicated the stored capacity and energy at 3.7V 10000mah 37Wh and after the boost DC converter, i.e. at 5V – more than 6300mah 31.5Wh: 
The model is available in two colors – white and black: 
Dimensions and weight:
The dimensions of the PB are small, only 156mm*77mm*12mm. One of the features of this PB is its thin body, only 12mm: 
Compared to the PN-963 model, the reduced thickness of the case is achieved due to a slight increase in overall dimensions. Here is a comparison with the mentioned previous model PN-963, as well as a thousand note and a box of matches: 
The weight of the PB is small, only 224g, 3g less than stated: 
Included charging cables:
The kit includes a flat USB->micro USB cable, about 55cm long, which can handle high currents without problems: 
The male USB plug contacts are gold-plated to reduce losses at high currents and protect against oxidation: 
This cable is intended for charging the power bank itself, as well as for recharging gadgets with a microUSB connector, if the built-in cable is not suitable or is busy. One of the highlights of this model, as mentioned earlier, is the built-in microUSB cable, about 7 cm long, allowing you to do without an external cable with a sufficiently charged PB. I was wondering what quality it was, so I did some testing to see if there was any voltage drop under different loads. The idle voltage at the PB output is 5.04V, three measurements are 1A, 2A and 2.5A.
Due to its short length, the losses on it are minimal (4.97V / 4.87V / 4.83V): 
And in the supplied cable you can already feel some voltage drop, although it still copes with a solid four (4.86V / 4.69V / 4.63V): 
Well, for comparison, a meter-long Orico cable, in which the drawdown is almost the same as that of the complete one (4.83V / 4.66V / 4.62V), although it is 50cm longer: 
But do not forget that the Orico cable is quite rough and not very mobile.
What can I say - the built-in cable is quite good and to minimize losses, it is better to charge through it. Since this PB model has two outputs, when using the built-in and external cable, you can simultaneously charge two gadgets: 
Features of charging PB Pineng PN-951:
This PB model can be charged with a current of 2A, which is good news (in fact 1.9A): 
For those who doubt the capabilities of charging doctors, measure the current in the supply circuit break (measured using the previously reviewed gadget): 
The Juwei charging doctor also shows a charge current of about 1.9A, and the filled capacity and energy are equal to 8730mah / 46.15Wh, respectively: 
Unfortunately, Pineng PN-951 does not support any technology fast charging, and given the considerable capacity of the built-in batteries, it would not be superfluous at all. I hope the developers will take this shortcoming into account and implement it in future models. The company's website mentions that fast charging will soon appear in new models.
One more interesting feature is the function of simultaneous charging/discharging (independent channels) or as it is popularly called “through charging”. Its essence is that by connecting, for example, a smartphone to a given power supply unit for charging, and the power supply unit itself to the network adapter/power supply unit, both devices will be fully charged, which is very convenient. This function is not new and is present in almost all Pineng PBs. The only limitation in this model is that the output current is limited by the charging current and is no more than 2.2A (the charging current increases slightly), and the output voltage is slightly reduced: 
When the load increases, the protection is triggered, and when the adapter/power supply is disconnected, the output parameters return to normal, i.e. as an uninterruptible power supply it can only operate up to 2A.
Testing the “useful” capacity of the PB (how much is at the output after the converter):
- Useful capacity– how much we actually get is calculated after the converter. The PB usually contains a boost/buck converter, which is far from 100% efficient, so by raising the voltage from 3.0-4.2V to 5V, it loses some energy (heating, inefficient components, etc.).
The manufacturer honestly states that the actual output capacity is more than 6300mah, i.e. at the maximum standard load we will not get less than this value, and at a light load, accordingly, we will get a little more. Let's check this with the help of “folk” indicators, aka charging doctors.
First, let's use the Juwei electronic load to see what the converter is capable of. At idle and 1A load, the output parameters are excellent (5.04V / 4.98V): 
Let's move on. At 2A and 2.6A, the output voltage is still normal and sags slightly (4.92V / 4.89V): 
Not every PB can cope with such a load. At currents greater than 2.8A, the output voltage begins to decrease noticeably, but even with this voltage level, most gadgets will “start up” (4.75V / 4.57V): 
Total, almost 3A at the output - an excellent result (the white doctor slightly underestimates the current). The previous successful model PN-963 had two independent output ports (1A/2.1A), and the maximum current on this port was about 2.2A. Here, the developers somewhat simplified the circuit and combined the output ports (to put it roughly, they parallelized them). But there is a big plus in this - from this power supply you can fully power “gluttonous” tablets, as well as mini PCs with an appropriate adapter (for DC). In the latter case, you will get some kind of uninterruptible power supply. The only limitation is that at currents of more than 2.5A, the electronics of the power supply unit heats up noticeably and the protection periodically trips.
Here is an example of simultaneous loading of all output ports: 
As you can see, the output is about 2.8A, the drawdown is about 4.8V.
Next in line is to discharge the PB to a minimum with an electronic load and a Juwei tester with a current of 1A in order to evaluate the useful capacity at a typical load. The output was 6760mah / 33.73Wh: 
As we remember, the manufacturer declared no less than 6300mah / 31.5Wh. Well, a very good result. Since in my previous PB tests I used a homemade load and a white charging doctor, for the sake of sport I tested this combination: 
As you can see, with an average load current of 1.55A, the output was 6740mah. For those interested, under similar conditions, the previous model with a mirror display PN-963 showed 6653mah, so we can safely conclude that the circuitry in the PN-951 has undergone some changes for the better.
Well, check the manufacturer’s statement about the minimum readings, that is, discharging the PB with the maximum nominal current. I decided to load a little more than stated, namely 2.2A (the manufacturer indicated 2.1A). In this case, the voltage sags within the permissible limits (4.9V). The capacity result is quite expected - 6414mah / 31.86Wh: 
Everything corresponds to the stated parameters, as they say, a brand is a brand.
In total, this model has excellent circuit design and allows you to obtain high output parameters, and all thanks to the fact that there are Li-Pol batteries inside (with a high discharge threshold in the region of 3V), which provide almost all the capacity. This PB shows simply excellent results.
Disassembly of PB Pineng PN-951 10000mah:
It is problematic to disassemble this PB without losing its appearance, since there are tight latches along the entire perimeter of the case. It is thanks to the latches that there are no wobbles or squeaks - everything is tight, and you immediately get the impression of a quality thing. Here's what's inside: 
Pros:
+ brand, quality guarantee
+ stylish appearance
+ thin, durable body (doesn't scratch or scratch)
+ high usable capacity
+ two parallel output ports with a maximum current of almost 3A
+ high charging current of 2A
+ simultaneous operation of charge/discharge modes (“through charging”)
+ the presence of all kinds of protections (against overdischarge/overcharge/overvoltage and short circuit at the input and output/excess current at the output/overheating of the electronic filling/incorrect connection)
+ presence of built-in cable and Lightning adapter/adapter
+ price
Minuses:
- lack of support for fast charging technology
Conclusion: one of strengths This model has a high output current, which allows you to power demanding gadgets, and thanks to “pass-through charging” it can be used as uninterruptible source power supply for mini PCs or similar devices. Unfortunately, this PB, like other models from this company, does not support fast charging technology, so they are not so popular, but for those who are not in a hurry and do not want to “spoil” the battery with fast charging, this model is an excellent choice, I recommend it for purchase ...
Every year new smartphones appear, more and more powerful and voracious. Innovations in the field of batteries are not yet expected, which means that a power bank (power bank, external battery, portable accumulator) remains the only solution for those who often live far from electrical outlets.
What are the differences between external batteries?
Portable power supplies, unlike smartphones and other types of advanced technology, cannot boast of much variety. And this is quite logical. Batteries - they are batteries, but you still need to know something about them.
Capacity and related dimensions
The most important parameter of an external battery is its capacity, which the manufacturer usually indicates in milliamp-hours (mAh). Roughly speaking, this is the amount of energy that a battery can store (but not transmit).
Please note: due to the fundamental laws of physics, no external battery can transfer 100% of the stored energy and no smartphone can fully absorb the energy received. Part of the resource is always lost during voltage conversion, and a certain amount goes into heat.
On average, total losses range from 30 to 40%, although some (and usually more expensive) models of external batteries and smartphones can boast efficiency of about 90%.
Thus, it is incorrect to determine the number of possible charges of a smartphone with a known capacity of the built-in battery from a power bank with a known capacity using simple division. The loss factor must be taken into account. Moreover, for reinsurance, it is better to take it at the upper limit, that is, at least 35%.
To put it simply, a power bank with a declared capacity of 10,000 mAh will in practice transfer approximately 7,500 real mAh, which means it will fully charge a smartphone with a battery with a capacity of 2,500 mAh not four times, but only three.
Please note that the above calculation is a very average and quite optimistic. You can only check the real losses when charging a specific smartphone from a specific external battery in practice.
In addition, physics requires a direct relationship between the capacity and mass of the power bank. To store more energy, the battery must be heavier and larger.
Connectors
The vast majority of external batteries, and especially those, are sold without cables. It is assumed that you will use the cord that came with your smartphone. Accordingly, the connectors on the battery and cable must match.
It may seem that you don't need to pay attention to connectors because all smartphones have the same wire with standard full-length USB on one end and microUSB on the other, but this is not so.
For example, the included Nexus 5X cable has USB-C on both sides. And in order not to buy additional wires, you will have to look for an external battery with just such a connector, both output and input, or purchase an adapter.
Kanex GoPower Slim Aluminum USB-C
Some manufacturers, such as Motorola, include a plug with a permanent cord in the package of certain smartphone models. In this case, purchasing an additional cable is inevitable.
There are power banks with a built-in cable. In this case, it is important to make sure that the connector fits your smartphone.
EasyAcc iChoc 5,000 mAh Ultra Slim External battery current output and fast charging
The external battery charges the smartphone, which is great. Even better if he does it quickly, right? The charging speed depends on many parameters, but the determining factor is the output current of the power bank. It must be no less than that provided by the smartphone manufacturer.
It’s easy to find out the optimal amperage for your smartphone. Take the plug that came with the device and look at the OUTPUT value.
Output current It will say something like 5 V - 2 A. You need the number next to A because current is measured in amperes.
You can find out the output current of the power bank in the description or instructions. If an external battery has more than one output connector, the current strength is sometimes indicated directly on the case next to each connector.
HP 7,600 mAh Power Pack Slim Portable If you have two or more connectors, remember that the total current output of the power bank is limited. For example, a battery may have two outputs of 2.5 A each, but produce no more than 4 A in total. Accordingly, when two devices are connected at once, each of them can receive no more than 2 A.
If the output current of the external battery is less than that for which the smartphone is designed (for example, 1 A for a power bank and 1.5 A for a smartphone), then charging will still occur, but noticeably slower.
There is no need to be afraid if the power output current of the external battery is higher than what it is designed for. mobile device(for example, 2 A for a power bank and 1 A for a smartphone). Mobile devices have built-in protections that limit the amount of incoming current to an acceptable value. Simply put, your smartphone will not explode or melt.
For the same reason, your mobile device will not charge faster if you use a plug or power bank with an output current higher than that provided by the manufacturer.
Let's say you find an external battery with a suitable output current, but the supplied plug still charges the smartphone faster. What's the matter? Most likely, your smartphone supports some kind of accelerated charging technology like Quick Charge 3.0, Quick Charge 4.0, or an option with its own name from a specific manufacturer (for example, mCharge from Meizu). Look for a power bank that is compatible with the fast charging technology used in your smartphone.
Now power banks with smart fast charging technologies like PowerIQ are gaining popularity. In theory, they recognize the device connected to them and supply the optimal current for it, but in practice this does not always work and not with all smartphone models.
External battery input current
No matter how capacious an external battery you buy, its own energy reserve will sooner or later be exhausted. It’s nice when a power bank quickly charges a smartphone, but it’s even nicer if it charges quickly itself.
The charging speed of a power bank is determined by its input current, voltage and the presence of one or another technology that ensures more rapid replenishment of its own charge. There are now external batteries that can be fully charged in less than 30 minutes.
Please note: the power bank's own charging speed does not affect the speed at which it charges the smartphone.
But lack of understanding of technology and gaps in English knowledge can mislead the user. For example, you see a power bank that says something like 5 minutes charge. You might think that this miracle device charges your smartphone in 5 minutes, but in reality everything is different.
Let's say the capacity of a particular battery is 10,000 mAh and it is fully charged in 20 minutes. In this case, in 5 minutes it will replenish approximately 2,500 mAh. And this charge is really enough to charge a typical smartphone.
The problem is that the charging time of a smartphone is limited by its own maximum input current and the availability of support for one or another fast charging technology.
Simply put, the pretentious phrase 5 minutes charge actually means: “This power bank only needs 5 minutes to get the charge necessary to further fully charge the smartphone.” Don't get caught up in marketing hoaxes and improve your technical literacy.

No matter how well your smartphone holds its charge, it periodically runs out of charge at the most inconvenient times. We stayed late somewhere, forgot to charge it in the evening, etc. Well, frankly speaking, not all phones are able to survive even daylight hours with very active use. Since replaceable batteries have now become almost an anachronism, external methods of “on-the-go” recharging of devices have come to the fore. In particular, these are cases with built-in batteries and universal external batteries. I won’t tell you about the first one; in my opinion, it’s not the most convenient option, and it’s also ugly (remember the heated discussions of the new thing?). But carrying a small “block” and a cable for it in your bag is not at all difficult. If something happens, pull out the cord, plug it in - and continue to use your phone/tablet without worry.
I’ll say right away that there are plenty of external batteries on the market. Especially on all kinds of “aliexpress”. However, personally, I would be wary of taking a very cheap Chinese “noname”; after all, charging is a serious matter; if you use low-quality accessories, you can ruin an expensive phone.
Capacity - 10,000 mAh. Price - 2500-3500 rubles. The device is compact, but relatively heavy (281 grams). It looks solid and has a charge indicator. It has a “smart” chip that recognizes what type of device is connected and supplies the required current (up to 2 amperes). Has two USB ports for simultaneous charging of two devices. The lithium-polymer battery, unlike lithium-ion ones, has a higher energy density per unit volume and mass. Capacity - 5,000 mAh. Price - 2000-3000 rubles. Simple in terms of design “brick” small sizes, weighing only 140 grams (as average smartphone). The brand is respected - everyone who uses UPS knows it. The battery has an LED screen that displays the charge level. There are also two USB ports. One outputs 1A - for phones, the second 2.4A - for tablets. Lithium polymer technology.
APC also has a 10,000 mAh external battery, which is slightly more expensive.
Capacity - 10,000 mAh. Price - 1500-2000 rubles. Perhaps the most popular external battery. At least, if you ask for advice, they recommend it most often. The secret of success is simple - Xiaomi has a reputation as a young brand that produces inexpensive and high-quality devices. The Apple-style design is also extremely successful; the device with an all-metal body looks great next to Macbooks, iPhones and iPads. Yes, it’s great without them too!
The battery is lithium-ion, weighs 207 grams and produces a current of 2.1A. There is a charge indicator and one USB output. They also sell multi-colored silicone cases for Xiaomi batteries!
I’ll add that in addition to the “ten thousandth”, the Xiaomi product line has a compact 5,000 mAh battery and “monster” batteries of 16,000 and 20,000 mAh. Just keep in mind that Xiaomi external batteries are very often counterfeited. Choose your seller wisely and unique code Check the purchased product on the official website.
4. OnePlus Power Bank
Capacity - 10,000 mAh. Price - 2000 rubles. A new product with a lithium-polymer battery from another young and promising brand from the Middle Kingdom. It weighs 222 grams and, unlike Xiaomi Mi, has two USB outputs. Produces 2A current and has a charge indicator. The black version has a body that is pleasant to the touch (reminiscent of suede), while the white version is made of smooth plastic.
7. Samsung EB-PG850B
Capacity - 8,400 mAh. Price - 1800-2300 rubles. The large South Korean manufacturer also did not stay away from external chargers. The device weighs 210 grams, produces a maximum of 2 amperes, and has a charge indicator. Feature of the battery - there is one USB port and one retractable microUSB cord. That is, there is no need to carry a cable with you. Only this is an option for charging in a pocket or bag; using such a short cord on the go is inconvenient.
The EB-PG850B is available in colorful designs with animal prints. They are more expensive, but part of the funds goes to supporting endangered species.
Samsung also has other external batteries with smaller capacity. For example, 3000 or 5200 mAh.
Capacity - 10,000 mAh. Price - 1300 rubles. Standard external battery bar with two USB ports (current strength - 1A for phones and 2A for tablets). Weighs 200 grams.
You won’t carry such a “monster” with you every day, because the battery weighs 550 grams, and in general it’s too big. But it has as many as 4 USB ports and you can charge 4 devices at the same time. The output current is no more than 6.9A (common for all USB ports). It is possible to simultaneously charge the battery itself and other devices (with its help).
I’ll mention one more bonus interesting view external batteries - they are built into backpacks. For example, the new ENERGI+ BACKPACK from TYLT with a 10,000 mAh battery and a well-thought-out cable system. Also interesting is the SunLabz Solar Charger Backpack - a backpack with a 10,000 mAh battery (charged using solar energy) and a 1.8 liter water capacity.
