BlitzWolf was nice enough to send me a BlitzWolf BW-P3 on the day of release, so I could put it though the wringer and review it in this Power Bank Capacity Check, a series of powerbankreviews I've been doing for some time in Dutch, but wanted to try to do in English as well. So here we go, a first attempt at a review in English.
As you might have guessed from the model number, this is BlitzWolfs’ third powerbank, a successor to their BW-P1. With an upgrade to QC3.0 and the addition of a second (5V) USB-port I think this might be a worthy successor too.
Unfortunately, the first batch of production has an issue with the 5V/USB port. As one of the first ones to receive it, I kind of discovered this issue; the port stops output after some time, this can be 90 seconds, but it can also be 5 minutes. Pressing the button restarts output, but this keeps happening until the powerbank has reached a certain level, I guess. The QC-port does not have this issue.
At first we hoped this was a standalone issue, one bad unit, but after a couple of days I found some users that had the issue, and complaints were coming in at Banggood.
As an official BlitzWolf dealer, BangGood has told me that powerbanks that are shipping now do not have the issue.
Unboxing

A brown cardboard box bearing the BlitzWolf logo, with in it : a user manual, a warranty card, a micro-usb cable and the powerbank itself.
Top and bottom panel, with ports, powerbutton and specs…
The casing, in anodised and sandblasted dark purple aluminium is really impressive and makes this powerbank kind of a looker. No sharp edges or corners to hurt your hands and/or ruin your pocket.

Performance 5V
The first and only charging test in this edition of PBCC will be at 5V/USB, because this powerbank can only be charged via 5V/USB.It was done after discharging the powerbank right out of the box.
It took 5 hours and 52 minutes, reaching a capacity of 40,639Wh (7.916mAh @ 5V) which looked like it was a little on the low side.
The discharge test resulted in 31,454Wh (6.439mAh @ 5V).
Performance QC (12V)
Charging this powerbank using QC is not possible, it only accepts 5V/USB at 2A max as an input. Hence, the absence of a QC charge test.
Discharging the powerbank using a Xiaomi 20.000mAh powerbank as a load resulted in 28,505Wh (2421mAh @ 12V)
But, these results all seemed to be a little on the low side for me, so I retested the powerbank using a ZKETech EBD-USB+, with the following results :
Charge test 5V/USB : 39,94Wh (7.742mAh @ 5V)
Discharge test 5V/USB : 31,38Wh (6.419mAh @ 5V)
Discharge test 12V/QC : 28,94Wh
Not that much of a difference. After comparison of all results to another 3-cell 18650-based powerbank in the Google Sheet this powerbank performs a tad bit better than it’s competitor that does not have the addition of either QC or a second port.
If you’d like to compare the results of this PBCC this the results from my other tests, you can check out this Google Sheet.
The whole shebang…
Conclusion
This beautiful dark purple powerbank performs a little bit better than other powerbanks in that realm. When looking at the percentage of output over input, this even takes top ranking. All that, with the bonus of a second QC-enabled USB-port, makes this powerbank a winner in my opinion, certainly at that price.
This powerbank is for sale at BangGood.
