Only apply to the power bank manufactured by Jiehua Technology.
Li-Polymer, height:65mm Diameter:18mm Capacity:2200mAh
Length 94(mm) × width 23(mm) × Thickness 23 (mm ), Net weight:74g
Use electronic load meter,DC,figure oscillograph to test under temperature+5°C~30°C,humidity40%~60% R.H
Ripple and noise
Use computer USB cherge this battery
500mA CC discharge
Static power consumption
5. Mechanism performance test
To press x,y,z 3 directions after full charge,each direction up, at
10HZ~30HZ to scan cyclely 30min.
Vibration frequency 10HZ~30HZ displacement amplitude (single amplitude of vibration 2mm)
The electric performances are OK after vibration.
After full charge, drop it from 1000mm height to positive and negative of total 6 directions of X,Y,Z, make it drop on the 18mm-20mm wooded board. 6 directions each.
The electric performances are OK after drop freely.
6. Safety performance test
Test method and condition
Over-charge protection test
Charge it 180 hours continuously with charger
Each cell voltage is 4.15V±0.05V
Over-discharge protection test
Discharge it 24 hours continuous with 500mA current.
Each cell voltage 3V±0.1V
Make the output port short-circuit .
Stop short-ciruit, recharge ,every electric performance are OK
Discharge over-current test
Make the electronic load meter at CC mode 2A.
The output voltage ≤3V
Cv pattern test
Make the electronic load meter at CV mode 4.2V.
The output current 800mA±20mA
Low consumption - static power consumption is low
Pocket size - easy to take on the go
LED flashlight - 2 in 1 ( power bank and flashlight)
Free visual for capacity - intelligent capacity indication, press showing
Safe protection - over-charge, over-discharge, over-current, short-circuit protection etc
1 LED on: 5%-30% capacity
2 LEDs on: 30%-55% capacity
3 LEDs on: 55%-80% capacity
all LEDs on: 80%-99% capacity
All LEDs out: less than 5% capacity
