Review on Enhanced Akozon Solar Charge Controller: LCD Display MPPT Solar Panel Controller for Lithium Battery Optimization by Avishai Menon

Photo shows a typical solar panel or battery power cable and device connector. They are commonly known as solar wire, usually 10 AWG. As shown, the connectors are too small to accommodate 10 AWG wire. Reducing the wire gauge would be grossly inefficient, and efficiency is the key when choosing a more expensive PWM solar controller. Luckily, Revain has a good returns policy. The unit appeared to be well built, such a shame they downsized the cable connections.
