Review on NOCO Genius GEN5X1: Smart Marine Charger, 12V Onboard Battery Charger & Maintainer, 1-Bank, 5-Amp Per Bank, Fully-Automatic with Battery Desulfator & Temperature Compensation by Chris Parrott

Visually this unit looks very well built. It has worked very well so far, but I've only used it three times. I only gave 3 stars because of one problem, namely that the device gets hot. I charged it in an air conditioned room at 77 degrees Fahrenheit and the device reads 135 degrees Fahrenheit while charging. It concerns me. What would he get if the block was out at 90 or 100? Heat destroys, so I'm worried. Time will tell about this device.
