Review on πŸ”‹ OptiMATE 4 CAN-bus 8/9-step 12V 1A Battery Charger-Tester-Maintainer - Ultimate Solution for Battery Saving by Tim Rushing

Revainrating 3 out of 5

Is working. but. in jump starters, chargers and portable power packs

It works but I have to trust it to do what it's supposed to because with all the lights and flashing I don't understand what it's doing or how to do it "reasonable" changes settings if necessary. I'm an IT professional with over 35 years in the technology industry and this is the ONLY device I've come across that doesn't make any intuitive sense. Put an ugly screen on it and use English for god's sake. we don't speak the language of flickering, flickering, light. Close it to change settings. INDEED!?! Put a physical switch on it. who designed this thing?

Pros
  • GOLS certified
Cons
  • Functionality
