Frequently Asked Questions - SLIGEN2200 SereneLife
How do I charge the SLIGEN2200 power bank?
Connect the included USB-C cable to a wall charger with at least 5V/2A output. The LED indicators will display the charging progress. A full charge typically takes 6-8 hours.
Can I charge two devices at the same time?
Yes, the power bank features two USB-A output ports for simultaneous charging. The total output is capped at 5V/2.4A, so each device may charge a bit slower when both are connected.
What devices are compatible with this power bank?
It can charge any USB-powered device, including smartphones, tablets, Bluetooth earphones, and handheld consoles. It is not intended for high-power devices like laptops.
How do I check the remaining battery level?
Press the side button to activate the 4-level LED indicator. Each LED represents approximately 25% of remaining capacity. When only one LED is on, recharge soon.
Is it safe to leave the power bank charging overnight?
Yes, the built-in protection circuitry prevents overcharging, overcurrent, and short circuits. However, unplugging it once fully charged is recommended for energy savings.
Can I carry this power bank on a plane?
Yes, it has a capacity of 81Wh (< 100Wh), so it’s generally allowed in carry-on luggage. Always check your airline’s policy for power banks.
How should I clean and maintain the power bank?
Wipe the exterior with a soft, dry cloth. Avoid liquids and cleaning agents, and keep the ports free from dust and moisture.
How long does the battery last?
The rechargeable lithium-ion battery supports roughly 500 charge cycles before noticeable capacity loss. Storing it in a cool, dry place helps extend its lifespan.
Can I use the power bank while it is being charged?
Yes, pass-through charging is supported, allowing you to charge the power bank and connected devices at the same time. Note that this may slow down the power bank’s own charging.
What should I do if the power bank becomes hot during use?
Stop using it immediately and let it cool down in a well-ventilated area. If overheating persists, discontinue use and contact customer support.
