Comes precharged, and ready to go! So far I've had no problems out of it, it charges pretty quickly.

Just bought, not used yet but like design and it works! Purchased another brand previously, didn’t work and can’t get in touch with company to return.

Easy to use. Nice quality and easy to take with you when you are on the go. Have it charge and ready should your power go out.

You can charge two phones at once ! Needed it because we are about to get a storm and needed a back up if our power goes out.
