XIAOMI POWER BANK 2 10,000MAH REVIEW

This is the lathử nghiệm offering of the Xiaongươi portable charger line, very similar to lớn the previous “Xiaomi Power nguồn Bank Pro” Model which also has a 10,000mAh battery. Key differences are the micro-USB instead of the USB-C port và the price. I’m a big bạn of Xiaomi portable chargers and I immediately pre-ordered mine when it appeared on BG. This is not a free-cống phẩm đánh giá as I paid full price for it

Specs from Xiaomi:Model: PLM02ZMMaterial: Aluminium AlloyCapacity: 10,000mAh 3.85V ( 38.5Wh )Product weight: 0.250 kg Dimensions: 130 * 71 * 14.1mmBattery Type: Lithium polymer batteryInput: 5.0V2.0A, 9V/12V18WOutput: 5.1V2.4A 9V/12V15W MAX

One of the reasons I love sầu Xiaomày power banks is because they state all the numbers in the spec, including the energy rating which is useful to measure efficiency. This version uses a 3.85V battery which gives it a slight advantage in energy as compared to lớn 3.6V & 3.7V chemistry. Higher nominal voltage và an extremely efficient conversion module gives the Xiaongươi 2 the almost unbelievable results in the discharge tests (See below).

Unboxing: It comes with a short USB cable và a brief instruction manual in Chinese (not pictured)

Build chất lượng & interface:

The Xiaongươi Power nguồn Bank 2 is very sleek & can easily be confused with a 5,000mAh power bank. Being made from an aluminium casing, build chất lượng is great and it feels very solid.

Operation & performance:-It has auto start when a device is connected-Will automatically turn off after 30 seconds if a load is not detected-One single button operates the power ngân hàng, it will turn on the output or restart it when pressed.-Double clichồng activates a low current mode, designed to charge/power low power devices such as bluetooth headphối, USB lamp, keychain flashlights, etc. These devices draws very small of current & in normal mode would not keep the power on. -Pass-through charge is possible but QC is disabled for both input and output.

“Real world” device compatibility test:When doing tests on a power ngân hàng it is much different to lớn use a USB load than a real device. Most of the times a dummy load will force the power ngân hàng to lớn put out certain power while in a real world situation it will not do the same with a phone or other devices. My devices for this thử nghiệm each have sầu certain characteristics when it comes to drawing power:

-iPhone 7: Charges up khổng lồ at 2A, but limited khổng lồ 1A if the coding is not correct.-YZXstudio 8th Gen powerbank: will automatically detect the output & switch lớn highest possible charging voltage (12V). -Aukey 30,000mAh powerbank: one of the few devices to lớn draw 2.4A, some chargers don’t provide Apple 2.4A coding or can’t handle this current & will trip.

Results:-iPhone7: Charged fine at 5.2V/2A -YZXstudio powerbank: Maximum charge rate detected was 12V/1.2A. The YZXpowerbank will draw as much current as possible until the voltage drops 0.5V. This is inline with the specs, 15W
12V Max.-Aukey powerbank: Charged fine at 5.1V/2.4A

The included USB cable is the flat type và measured 0.09 Ohm resistance at 5V 2A. This is good compared to my other short cables.

Charge test:-Maximum input đầu vào using a QC3.0 adapter was 9V/2A-From empty lớn full it only took 3hr 38min, impressively fast.-49.6Wh required to fully charge with an efficiency of 77%-After being fully charged it draws 33mA while idle-There is a current dip to 0 every ~10 minutes during the CC phase, this only lasts a couple seconds but it is enough for the graph to pick it up. I think this is how it tells the battery voltage without applying a charge. The dip is sightly visible in the voltage line because the Anker PowerPort+1 has voltage compensation when under load (lower current = lower voltage, as you can see towards the over of the charge). I will have sầu to test it again with another charger and see if this happens as well.

This is my new style of graph for my power bank Review, now includes the energy axis. That is a nice and sharp CC/CV drop.

*

Discharge tests:

5V/1A: output was completely flat, putting out 36.84Wh in 6:57 & achieved an amazing 95.6% efficiency. This is one of the highest of any power ngân hàng I’ve sầu ever seen, a very cthua thảm match lớn the YZXstudio 8th which is several times more expensive.

*

5V/2A: nice và flat output like in 1A chạy thử, slightly lower energy.

*

9V/1.5A: output remained above sầu 9V until 2:03 & started a slow drop, final reading was 7.01V at 2:25.

*

12V/1.5A: It wasn’t able lớn sustain 12V for long và started a slow drop from the 30 minutes mark. The specs says a maximum of 15W for both QC output & I was drawing 18W in my tests. This won’t be a problem when used with a điện thoại thông minh because in 30 minutes the current would have sầu already dropped from 1.5A.

The complete chart

Notes:-Spec shows 6,900mAh of output capathành phố at 5V : 1A rate & I got 6,959mAh. Not something you see everyday! -The internal battery is LiPo with a nominal voltage of 3.85V, so compared to lớn a 3.7V 18650 power ngân hàng of the same capacity there is a small energy increase.-Compared to the older Xiaongươi 10,000mAh (pictured above), I’m getting roughly 7Wh more at 5V : 1A which is a dramatic 23% increase. This is enough lớn give sầu an extra full charge lớn a smartphone with a ~1300mAh battery.

Final words…I’m overall very impressed with the performance of this power ngân hàng, given its compact kích cỡ và price I would say this is simply the best 10,000mAh power bank you can buy.

*

The good:-Sllặng, lightweight và great build quality.-Extremely high efficiency, out-performs most higher capađô thị & more expensive sầu power banks.-Strong output enough khổng lồ charge the most power hungry devices. Recharges very quickly as well.
