Charges all at one time. They arrived and first I was highly impressed by the quality. I bought this for my travel trailer, but the pictures show it at my house where I set it up to test it before installing it in the trailer. I purchased them in light pink and they look great. Runs a little big but I like the oversized look for pjs (for reference wearing a large, 5?5? 170lb). Its a phone, its running the latest version of Android but thats about it. The pieces arrived wrinkled and distorted. Bought a black pair 3 years ago along with navy blue & bought a black pair again from Amazon. This is the solution for using a trunk rack. All of this applies to this purchase.
