- What components are attached to an power bank?
It depends on the product model. Every power bank at least comes along with an instruction guiding you how to use it and a micro USB cable which helps connect your mobile device to a power bank. We suggest you refer to product instruction before buying it.
- How to maintain the battery?
- Please charge its power to over 30% of capacity if you're not going to use it for a long time. We suggest you keep it at -10-40 ℃ in a dry environment so as to maintain the battery best performance. Please don't use up all power. It will present precharging status in the next selfcharging if you use up all power, and the charging time would require 2 or 3 hours more. So in this case, the selfcharging time slows down, and even the service life of battery may be shortened.
- What should we be aware of when using ROMOSS car charger?
We suggest you should avoid charging and talking at the same time because the mobile phone releases high radiation during charging. If the car charger is not in use for a long time, please unplug it.
