This automatic onboard battery charger is a high output portable charger, is completely automatic, and great for professional mechanics as they can be used for deep cycle batteries. Its 75-amps helps engines for emergency starting and the 12-amp fast charge helps to charge a battery in 2-5 hours. The 2-amp trickle charge charges a small 12-volt battery in 2-12 hours. It includes 2 LEDs which light up when the battery is fully charged and a 6 function rotary switch prevents overcharging of batteries.

I’m impressed by this product. I’ve used other jumpstarterdeals battery chargers before but the SE-1275A is the best ever. The things I like best are: Wide-mouthed alligator clips that clamp on easily and don’t slip off, automatic shutoff when a battery is fully charged, the rugged steel cabinet and overall quality construction.

If I could change anything about it, I would suggest adding readable instructions to the back of the cabinet, a longer electrical supply cord (one or two extra feet would be perfect), and a larger analog meter.

I have only used the charger in the 2A charge mode. It has fully met my need to recharge the battery in an auto that is used infrequently. I do wish that the instruction manual described more fully the changes that occur in the display as the charging progresses. They quickly sent another without any return needed, and the rep sounded like he was Po’d at his company for allowing so much junk to go out the door. Now I have two working and one dead for spare parts, and even after the hassle these are still the most for the กระเป๋า least on the market. You only other option is sears, and they appear to be made by Schumaker also, or harbor freight which should send its electric stuff with a death certificate.

Does the job. Well. It is not a mobile battery, it is a 3 speed charger. You need to be near an electric outlet. The 50 amp setting will not start a totally dead car, but leaving the charger on 10 amps for just a few minutes and then switching to 50 amp will. Do not leave the charger on 50 amps to charge the battery as this would be dangerous. I bought this to charge my Mom’s car battery which we used several other chargers on that didn’t work. This one got it started. I used the 10 amp setting for about an hour then used the 50 amp for a couple of minutes and it started right up. I have the same brand charger that I received about 20 years ago and it still works great. I hope this one lasts as long. It’s made of metal and seems pretty sturdy. My only critism is that on my Schumacher charger, there is an on/off setting and on this newer one there is not. Once you plug it in, there’s electricity going to the clamps. Make sure you have it connected to the battery before plugging it in.
