Adata PV100 4200mAh USB Battery Review

Performance

The short cable is just enough to have the battery sat behind your phone, meaning it is even possible to hold both the battery and the phone together while making a call without it feeling too clumsy.

Performance figures are one thing, but there really isn’t a huge amount to test on this device. From out of the box the PV100 was holding a 50% charge, more than enough to save the day should you pick one up at retail and be in need of instant power. After draining the battery via my smart phone, I left it to charge for a full cycle, which took just under 4 hours from my desktop PC standard USB 2.0 port.

With my battery on my mobile drained to 0%, to the point where the device would not power on at all, the PV100 immediately brought my phone back to life and had it charged to 100% in 40 minutes. It took around 10 minutes more to complete a full charge with the device powered on (standby mode).

In total I was able to get one full charge (0 to 100%) and one more 60% charge (0 to 60%) with the phone switched off. With the device powered on I was able to get one full charge (4% to 100%*) and a further charge to 52% (4% to 52%).

The PV100 was great at keeping my phone alive while using power-hungry applications, but of course these results would vary wildly dependant on the apps used. My phone dropped to 10% and I connected the battery, I was able to continue playing my game (Royale Revolt) on maximum brightness and the device still managed to reach a charge of over 90% before the PV100 ran out of power, the only downside being that my device was very warm from running the GPU and charging it at the same time.
