Review on Trackmategps Heavy Duty Waterproof Weatherproof Magnetic by Samuel Nguyen

I have this to plug in my Amcrest GPS so I can charge it all the time. This one is a bit bigger than their standard case, big enough for a 90* USB connector, and then I used a soldering iron to melt a tiny hole between the clamshells for the wire. Worked fantastic and now my tracker works all the time. The magnet is just as good as a double magnet, don't worry about it falling off.
