### ⭐⭐⭐⭐⭐ Review
*by J***K on 21 June 2020*

Recently purchased an electric Scooter (think electric MoPed). My second trip out I ran short on battery power and had to make a stop at a friend's home to charge up for a couple hours. Discovered when I got home that the outlet I used was a GFI plug that had been tripped and thus did not charge the batteries the previous night. This would have allowed me to check that condition. I intend to carry it with me to check outlets I can charge from when away from home.
