FAQ

Good questions, answered.

Which devices do the built-in cables work with?
The four on-board connectors — Lightning, USB-C, Micro-USB and USB-A — cover iPhone 16/15 and earlier, Samsung Galaxy, Google Pixel, iPad, AirPods and most Android phones and accessories.
How fast does it charge?
Up to 22.5W over USB-C (20W for iOS devices) — roughly 3× faster than a standard 5W charger. The LED shows a fast-charge indicator when high-speed charging is active.
Can I take it on a plane?
Yes. At 20,000mAh (74Wh) it sits within the 100Wh limit airlines allow in carry-on baggage. Always keep power banks in your carry-on, never checked luggage.
How many devices can it charge at once?
With 5 outputs you can power several devices simultaneously — for example a phone on a built-in cable and a second device via the USB-C or USB-A port at the same time.
What's covered by the warranty?
Every RONEGN power bank is backed by a 12-month limited warranty against manufacturing defects. Reach us any time at Service@ronegn.com and we'll make it right.

Power that goes where you do.

Slim enough to forget it's there, capable enough to get you through the day. That's RONEGN.
