Display not bright enough at perpendicular view. I have to look at 20 degrees or greater to see bright screen.

It works great, priced right. Easy to use overall a nice piece of machinery

BEST BATTERY CHARGER I HAVE USED IN MY 20 PLUS YEAR AUTOMOTIVE CAREER. THE DESULFATION MODE HAS RESTORED SOME, NOT ALL, BAD BATTERIES THAT OTHER CHARGERS WOULD NOT BRING BACK! I HAVE ORDERED 4 OF THESE CHARGERS NOW. THE OPERATION SEQUENCE FOR WHAT MODE TOOK ME A MINUTE TO GET USED TO. IF YOU AREN'T ON THE DESIRED MODE YOU WANTED AND ALREADY STARTED THE CHARGE CYCLE, UNPLUG AND PLUG BACK IN. START OVER WITH SELECTING THE DESIRED MODE.

This small charger can really do a lot. Easy to use, easy to read screen. It has actual buttons, old style that have a positive click and can be operated with gloves on. I really put it to the test by charging two 300ah batteries for 30 hours at 20 amp. The unit has a fan with variable speeds but did get pretty warm, so I turned it up on its side to expose the bottom to air and it cooled down. Very happy with this item!

Great

Great project, easy to use and keeps a nice even charge. I have been using it as a maintenance charger but it also charged a low battery all the way to 100%

I have only used it once so far on a couple 6-volt batteries connected to give 12 volts. They have been sitting for a couple of years and the desulfurize feature did its thing and brought them back to life where another charger could not. I have a couple more batteries that I hope it will do the same for.

This is a very versatile unit that can handle both lithium and lead acid batteries. It is relatively light weight for the amps it can put out. The auto and manual modes work well. The 35 amp setting made it possible to get my diesel truck running when we had a deep cold snap.

Does everything I need it to do!

Works well. Instructions lacking detail simple enough for an old country boy; thus, 4 vice 5 stars. Worked well, and did actually recover one of two duramax batteries just replaced!! Took a couple of days, but checks good and will be great for the clay thrower, so it paid for itself already! Have yet to be disappointed by Vevor!!
