Why is this power bank heavier and larger than others with similar capacity?

Because we use premium batteries that deliver true 40000mAh capacity with no false claims - every gram counts for real power!

Is it normal for the power bank to get slightly warm during use?

Slight heating due to efficiency losses in the conversion circuit is normal. The temperature of this Romoss Power Bank meets the temperature limits of the IEC62368 certification standard.

Why does the battery drain so quickly?

When the Settings selection screen is always on, both the screen and MCU are working, so it is normal that the battery drains quickly.It uses 15% of the battery in about 24 hours. We recommend turning off the display screen when not in use.

Why does charging stop at 80%?

Your iPhone may automatically stop charging at 80% to protect its battery from overheating, as part of iOS 17's thermal management strategy. Charging will resume once the device cools down. Moving it to a cooler spot can help speed up this process.

How can I keep my power bank in the best possible condition?

Charge your power bank regularly. Even if you don't use the power bank for a long time, remember to charge it every six months to keep the battery level around 50%. This is because power banks can discharge even when not in use.
