A:AnswerI'm not sure about harming it. I can tell you that when covid hit - business travel stopped for me. It sits in my small carry on suitcase and I just pulled it out (has been sitting idle for 8+ months) for upcoming travel and the battery was still 2/3rds charged and works just fine.
A:AnswerTheir is a small button on the side , push it and lights will come on. The # of lights will tell you if the battery is low or full. Max is four lights
A:AnswerWhen this is fully charged, it completely charged my iPhone 11 in a little over 2 hours. It’s lightweight and easy to carry with you when you’re away from an outlet. I tried charging another phone after it finished charging mine and it was still able to get that phone to about 75% before I needed to recharge the battery pack.
A:AnswerYes, charges it many times, even if you are on the iPad. This battery brings it to fully charged, then shuts off. When the iPad battery shows 30% just push the button again. Works Very Well. Feels great in your hand. Top Quality.
A:AnswerI just used the cord that came with it to plug into the power bank and then the other end into a USB port or either attached an outlet adapter and plugged into a regular outlet.
