Dynacharge DY-1420 Manual Wheel Battery Charger with Engine Start

good price and delivery have used twice once to charge and once to jump start worked great

seems to charge well, one thing I didn't see in the advertisement was the fact that you can only run it on 2 amp or 20 amp continuously, the 55-140 (not separate settings btw) amp setting will run 30 seconds @ 55 and 3 seconds @ 140, after which both require a 600 second (10 min) off time.140 amps @ 3 seconds to me is pretty much useless, as is 55 @ 30 seconds, no battery is gonna charge up enough to start a car in 29 seconds lol. oh well, ive paid 40 - 60 for the small chargers rated at 15 amps that don't seem to get anywhere near that rating on output. This charger does for sure, @ 20 amps charge voltage reads 14.8, @ 55 amps reads 15.7, definitely working, and that's on an oversized tractor battery.UPDATE: the clamps you connect to the battery leave a little to be desired, for the money though wouldn't take much to upgrade them.

Good product

Awesome charger, I have 2 trailers and their batteries can need charging after only a short while. This charger does the trick and they are charged within a couple of hours.

Received a product that was previously been returned to them by another customer. The product was dented and there’s a wire hanging inside that can be seen from the little holes in the back. Returned the product. I will try to order again.

The switches broke after the first few uses so I stuck it in the corner for a couple of years. Replaced the switches will some better ones then the low amp funcions stopped working after a short while. Used it strictly as a booster for ATVS and mowers and it worked fine for that until the batteries were all but dead on my diesel pickup. I tried boosting it and it kept tripping the internal breaker. Finally the batteries charged enough to start the pickup. Next time I used it to crank a generator and the transformer went up on smoke. I'd recommend a 200A minimum if planning on using one for vehicles. The cables are also too light gauge wire and the clamps are weak

If you're looking for a full size charger for $100 or less. This is the best you will get. Has limited duty cycles on the high amp scales. But does the job just fine even on my diesel vehicles.

Love this charger!
