Unboxing, features and real capacity testing

Specs:
- 3 outputs (2x USB-A + 1x USB-C)
- 3 inputs (micro USB, USB-C, Apple lightning) can be used for power bank charging
- 5V/3A total
- 80% energy conversion
- capacity 30000mAh / 111Wh (lithium polymer battery)

Discharge capacity tests:
- each port is able to provide 15W / 3A at 5V (not 1 or 2.1A as specified)
- measured capacity is 100.2Wh - very decent result, it seems that boost converter has better efficiency (more than 90%) or little better lithium cells were used

Power bank recharging:
- 134Wh, took 13h at 1.8-2.2A

Pros:
- good price (paid about $15 in Poland)
- real high capacity 100Wh at 5V
- 15W/3A from any output
- inputs in 3 convenient standards, almost any cable can be used for recharging
- pass through / UPS works ok

Cons:
- heavy - 600g
- slow recharging - only at 2.1A max - takes 13h from empty to full
- no real QC / PD, only 5V
