■ Cold Weather Usage
Cold temperatures (below freezing) can impact the battery capacity of the portable power supply.
If you are living in sub-zero conditions, the portable power supply is not able to deliver 400wh.
NEVER charge it in the sub-zero conditions, which will damage the lithium-ion battery and battery
capacity may not be recovered.
Low Temperature Charging Protection: In the sub-zero condition,the portable power supply will
stop charging automatically. It starts being charged again when temperature is over 5 °C.
Low Temperature Discharging Protection:
In an environment which temperature is -20 °C, it
would stop AC and DC output, then shut itself down in 15 seconds automatically; and it can only
output again when the temperature is over -15°C.
■ Storage and Downtime Maintenance
Failure to maintain your portable power supply by following steps can result in battery damage
which will void the product warranty.
1. Please charge your portable power supply at least to a level of 70% before storage and recharge
it every 3 months. Store it in a cool, dry place.
2. If the main power supply shuts down automatically because of lower battery capacity (10%),
please recharge it in 2 weeks. Otherwise, there is the risk that the battery capacity won’t be
recovered.
