Which devices support wireless charging with this magnetic power bank?
NVUU slim battery pack is magnetically compatible with MagSafe cases and iPhone 17/16/15/14/13/12 series
Why does the portable charger deliver fewer charges than expected?
A:Due to a 35% to 45% capacity los from battery cell and circuit inefficiencies during charging, a fuly charged 5000mAh Power Bank effectively provides about 2750mAh to 3250mAh of usable power to your devices.
Why does my phone heat up when it's charging?
Slight warmth in power banks during use is normal. Key note: Keep charging temperature below 104°F (aided by the aluminum alloy casing’s great thermal conductivity and heat dissipation). If overheating, remove and rest 1-2 minutes to cool.
What do the different colors of the power bank's indicator lights mean?
A:The red indicator light means the power bank is fast charging at 20W, while the blue indicator light means it is wirelessly magnetically charging.
Why does charging stop at 80%?
Your iPhone might charge more slowly once it reaches 80%—this is to protect the battery. It can also occur if the phone gets too warm while charging, as part of iOS 17’s thermal management. Charging will pick back up once the device cools.
