Just released in March. This is my 5th power bank that I will use everyday. $32cad + shipping, definitely not cheap with single USB port. It says it could charge up Macbook Air, so fair enough.
My previous power banks.
1. Cheapo 5000mah (18600 battery) - RIP
2. Xiaomi 5200mah (18600 battery) - gave it to my sister
3. Aukey 12000mah (Li-Ion)
4. Xiaomi 5000mah (Li-Ion)
5. Xiaomi (Pro version) 10000mah (Li-Ion)
vs LG V10
vs Xiaomi 5000mah
vs Aukey 12000mah QC2.0
old Xiaomi USB vs new USB Type-C charging cable. Not quite sure why type-C hasn't get popular these days.
Charging LG G4 is around 11.2watt, the voltage isn't quite stable for unknown reason. I haven't figured out why, it jumps +/-1watt
Charging iPad Air 2 only gets 1.3A = 7watt
At last, using my QC2.0 12V charger at home, it reaches 0.63-0.67A = 8W (the label shows it could reach 1.5A)
