The Olala 10,500 battery bank is a 2 port portable charger that supports Quick Charge 3.0 output. I’ve owned many battery banks over the years and this stands out because of one killer feature: quick charge. It can make a significant difference in charging speed if your phone supports it. iPhones, might not notice the difference, Androids that support Qualcomm Quick Charge will see the biggest difference. The battery bank is wrapped in metal and has a fairly substantial weight to it. It requires a press of the power button to output charge, it will not automatically start charging with a USB cable plugged in. I used a voltage/amperage tester with this one to measure capacity, current, speed, etc. and the charger had a stable voltage while charging and an 83% efficiency (about average). One thing I wish it had though is quick charge for charging itself – seems silly that it recharges a lot slower than it charges other devices. Since it supports QC output it should support QC input too. It charges itself a little slower than some other battery banks I’ve used – expect about 7 – 10 hours for it to fully recharge itself. Overall, if you want a quick charge battery bank the build and style of this one is pretty nice and its charge speed is consistently quick.
