Review on Thlevel Charger Voltmeter Waterproof Motorcycle by Dave Cavazos

The previous model was bought last year and died of wetness in the first heavy rain in Florida. The USB ports were plugged in, but there was no on/off switch on this model, while this update has it all covered. Very easy to install and can be used with or without a balance bike - just turn it off to keep the battery from draining. Charges devices very quickly and the digital voltage display is a nice improvement over the old LED chart. The only gripe is that the blue LED display is very bright at night and can't be dimmed when you're charging. My solution was to cover the readings with dark tape through which the numbers can still be seen but much darker.
