If the battery is C grade one, then explosion is possible to happen. But we are applying the safest li-polymer battery and imported Li-ion battery. And the PCBA has multi-protection: overcurrent protection,over voltage protection,short-circuit protection,battery protection(overcharge/Over discharge),temperature protection.
3. Can power bank charge all kinds of mobile phones?
Yes, it can charge all smart phones. Just different mobiles phones may need different adapters.
4. Why is power bank out of power after I charge my mobile phones once and twice?
It is something to do with the capacity of power bank, conversion efficiency and capacity of mobile phones. Normally the conversion efficiency is around 85%. And the voltage of battery is 3.7v, the capacity will be lesser after step-up into 5V during charging.
