ROMOSS Powerbank 30000mAh

Q: What conditions are needed for fast charging a phone with the power bank?

For fast charging via a power bank, ensure your phone, data cable, and power bank all support and are compatible with fast charging protocols, and connect to a fast charging port; note that charging multiple devices may disable fast charging.

Q: What is low-current mode for the power bank and how do I enter it?

Low-current mode is used for charging low-power devices like earphones; press the button twice to enter (indicators will flash) and press once to exit.

Q: 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.

Constant quality

I started buying these when they didn't know how good they are and were cheap. Now they cost more but I don't want to switch to anything else. This model made about 15000 km of cycling with me. I trust it.
