Really love this usb c charger because I can directly plug it to my phone cordless. Surprisingly, it holds charge for a relative long time when not in use. I don’t use it very often, but charge it twice every month to maintain functionality. This pocket juice portable charger is super small, I would say as slim as lipstick. Throw it into pocket or bag, you can barely feel it. And save you from cord power bank any more. Just pull off the cover and plug to your phone. This portable charger is not for those who think they can walk around and use the phone at the same time!!! This is really good for the moments that your phone is actually dead and need charge until you can make it to a plug. It has 4500MAH meaning this won’t keep your phone charge for more than than 1 hour and if your like some of the people in the review section that don’t read the description you will have a disappointing time.
