    Hmmm I’m not as impressed with this size one as I was the older smaller version. It won’t stay on to charge my headphones for some reason. Shuts off after like 30-60 seconds as if it’s not reading that something is plugged in to be charged. Jury still out if I like how it works on my phone as well.

    No, I would not recommend this to a friend
