7000 mAh ADATA X7000 Power Bank Test

1, Apr 2019

We have picked up another power bank from ADATA, this time a smaller in size and capacity and fancier looking compared to the other models we have tested so far. The 7000 mAh ADATA X7000 comes with mostly aluminum case where the battery is and a smaller plastic part where the electronics is housed, a slim, light and good looking power bank for sure. It comes equipped with dual USB charging ports and can charge two devices simultaneously with a maximum combined charging current of 2.4A. The supported input current for charging the battery inside the power bank is 2.0A, so it can be charged faster and can charge devices faster with up to 2.4A max current. Not to mention that the price of the power bank is quite attractive, making it an interesting choice for lower capacity model with faster charging options.

7000 mAh ADATA X7000 Power Bank Specifications:
– Capacity: 7000mAh (Rechargeable Li-Polymer battery)
– Colors: Titanium/ Blue/ Red
– Dimensions (L x W x H): 148.2 x 73.9 x 12.3mm / 5.8 x 2.9 x 0.48″
– Weight: 210g / 7.4oz
– Input: DC 5V/2A (Micro USB)
– Output: DC 5V/2.4A max (USB-A)
– Accessory: Micro USB cable, User Manual
– Warranty: 1 year


We have tested the 7000 mAh ADATA X7000 Power Bank with 1.0A constant discharge current as the more often used as well as with 2.4A as the maximum supported by the power bank. In both cases we are seeing that the electronics of the power bank manages to provide pretty stable and high (close to 5V) output and a very good capacity levels in terms of mAh and as a result in Wh as well. The voltage cure is not straight line like we’ve seen with previous models from ADATA, but a jagged one very similar to that we’ve seen in our 5000 mAh GP Portable Power Bank (FP05M) Test.

The performance of the 7000 mAh ADATA X7000 Power Bank in our tests:

– 5035 mAh at 1.0A load
– 4700 mAh at 2.4A load

– 25.19 Wh at 1.0A load
– 23.24 Wh at 2.0A load

16750 mAh ADATA P16750 Power Bank Test

26, Mar 2019

The 16750 mAh ADATA P16750 Power Bank is another high-capacity mobile power bank from ADATA similar to the 20000 mAh P20000D model that we have recently tested, but not quite the same. The ADATA P16750 comes in a pretty compact size for its capacity, uses a nice-looking plastic case and comes with a power button and LED light indicator for the charge level. It has dual USB charging ports and can charge two devices simultaneously, but with a maximum total output of 2.1A for both ports. The input for charging the power bank is 5V/2.0A, so that the large battery capacity would not mean a day needed for a full charge at just 1.0A charge current, though you need to make sure you use a suitable power adapter. Just like its bigger brother the P20000D there is also a LED “flashlight” feature that we find useless, but other than that it seems like a really good power bank taking into account the specializations and features.

16750 mAh ADATA P16750 Power Bank Specifications:
– Capacity: 16750 mAh (Rechargeable Li-ion battery)
– Colors: Black / White
– Dimensions (L x W x H): 130.7 x 75.0 x 25.5mm / 5.1 x 2.9 x 1.0″
– Weight: 375g / 13.2oz
– Input: DC 5V/2.0A
– Output 1 & 2: DC 5V/2.1A max
– Accessories: Micro USB cable, user manual
– Warranty: 1 year


Let us take a look at the performance of the 16750 mAh ADATA P16750 Power Bank in our discharge tests trying to figure out what the usable capacity is. We see good and stable voltage curve during both 1.0A and 2.1A constant current loads with just a slight hitch at the end of the 2.1A discharge where we see a more significant drop for a bit before hitting the completely discharged state of the battery. In overall a good performance regarding the available capacity at both discharge currents we have tested, though it would’ve been better if the maximum combined output for the two charging USB ports was more than 2.1A for this high capacity power bank.

The performance of the 16750 mAh ADATA P16750 Power Bank in our tests:

– 11637 mAh at 1.0A load
– 10655 mAh at 2.1A load

– 55.33 Wh at 1.0A load
– 50.65 Wh at 2.1A load

20000 mAh ADATA P20000D Power Bank Test

18, Mar 2019

Here comes a big power bank with 20 Ah capacity in the form of the ADATA P20000D Power Bank, their largest capacity model which caught our attention precisely with its big capacity, though we are going to be testing other ADATA power banks as well with smaller capacity soon. The ADATA P20000D is pretty big and weights almost half kilogram, but this is the result of the high capacity battery cells inside. The power bank is available in multiple colors and the one we have tested was the black version, though apart from the color difference they are using the same plastic case (being advertised as extremely fire, shock, and impact resistant). It is matte color mostly, though around the edges there is a glossy part that looks nice when the power bank is new, but easily and quickly scratches, so we are not that big fans of that design. Another thing that we do not like that much is the presence of a small LED light being advertised as a flashlight… that power banks simply does not need it as it is a sort of useless, but hey, another key sell point for 2 extra cents. What we find very useful and like is the display that shows the remaining capacity in percentage, it has a backlight as well and also displays the active input and outputs.

20000 mAh ADATA P20000D Power Bank Specifications:
– Capacity: 20000mAh (Rechargeable Lithium-ion battery 72Wh)
– Colors: Black / White / Yellow / Gray / Blue / Dark Blue
– Dimensions (L x W x H): 163 x 80.6 x 23.3 mm / 6.4 x 3.1 x 0.9 in
– Weight: 450g / 15.8oz
– Input: DC 5V/2A (Micro USB)
– Output: DC 5V/2.1A max. (Type-A USB)
– Accessory: Micro USB Cable; User Manual
– Warranty: 1 year


The 20000 mAh ADATA P20000D Power Bank comes with high capacity and that high capacity needs faster charging, though here we have a 5V/2A input that can easily take over 10 hours for a full charge of the batteries inside the device. There are dual USB outputs available, meaning you can charge two devices at the same time, though the combined output is 5V/2.1A, so not dual device fast charging, but two at 1 Amp each or one with thee higher charge current. Looking at the test results we are seeing good and stable voltage discharge curves – 4.94V at 1.0A and 4.8V at 2.1A, though we kind of expected a bit more in terms of actual usable capacity from this 20 Ah power bank… the results we’ve got are pretty much the average you could expect from a decent power bank. The high capacity is nice to have, but the bulky size and big weight certainly do not make that particular power bank from ADATA the best choice to always carry around with you in your bag or backpack.

The performance of the 20000 mAh ADATA P20000D Power Bank in our tests:

– 13544 mAh at 1.0A load
– 12560 mAh at 2.1A load

– 66.94 Wh at 1.0A load
– 60.15 Wh at 2.1A load
