And the LED indicator will light up all the time to show you the current battery life. Will turn off by itself after no charging activity.
Wow… I was not expecting Romoss QS05 power bank can charge so fast with 1A output. Well, tests were done without USB voltmeter as it can’t accept micro USB as input. So I did the old way – manual calculation on my devices like Onda V820w tablet and Galaxy S4 smartphone which can accept up to 2A input. Romoss QS05 is able to charge 60% of Galaxy S4 battery (2600 mAh) in an hour. This mean that it is output around 1.5A there. And it almost able to fully charge Onda V820w (with effective 3700 mAh battery size, calculated with USB voltmeter) in 3 hours (note – device charge much slower when battery level is near full). Seriously? Does it really have 1A output only? It performs just like 2A charger here. With 5000 mAh, it can fully charge most of the smartphones in the market and some small tablets as long as they are below 3600 mAh. As for self-charging, it takes around 5 and a half hour to do so.
Note – This power bank had been gone through 5 charge and discharge cycles to get accurate data and prove its stability. Yup, it passed flawlessly…

Yeah… I like Romoss Q Series QS05 Power Bank due to compact size and ease to carry around. Able to charge as fast as 2A charger here.
