Schumacher SE-1250 Manual Operation 10 and 30 Amp Charger with 50 Amp Emergency Engine Start

• 10 amp output recharges auto size lead acid batteries in 3 to 5 hours, 12 volts fast charge booster
• Will charge conventional, maintenance-free, deep cycle and low maintenance 12-volt batteries
• 30 amp fast charge increases battery power quickly
• Output increases from 30 to 50 amps when cranking engine
• Rocker switch with off position for safe, easy use

This battery charges is simple and does the job. It will put out 30 amps or 10 amps of current. I did not try the 50 jump start option, but I don't see why that would not work.

I am using this to charge batteries attached to a solar system, so I did not need a smart charger. I can charge the batteries when they get low with this and let the solar charge controller do all the fancy smart charging.

The device seems to be well build.

Update. I lowered the rating to 3 stars as I discovered that the charger will only put out 30 amps for 8 minutes or so. The good news is that there is a thermal switch that will turn it off, so nothing gets hurt, but this is not a 30 amp charger. It is a 10 Amp that can put out burts of 30 amps and 50 amps for a limited time.

When I got this item in the mail and opened the package, it looked like it had been thrown down a flight of stairs. The case was warped, the face plate barely held on, and the bottom was so bowed out that the unit wouldn't sit flat on my shop counter. The box was in pristine condition. Somebody bought this item, demolished it, and sent it back in for a refund. Obviously nobody checked it when it came back in...2 seconds would have told them it was probably broken. And it was. I was using it for anodising, and it totally ruined the parts I was working on because it only put out 10 amps instead of 30 (on both settings), and stopped working completely after 40 minutes.

One thing I will say about Amazon is that they did give me a full refund, which I appreciated...but there should have been someone checking the returns! How many other people are going to get sent this same charger? When does it stop being "NEW IN BOX"?
