I've been using this charger to charge 3 go kart batteries so far. It works great as far as charging them to 13V and slow trickle charge them over 13V. I like the fact that trickle charging is safe and no need to disconnect immediately after fully charged. So far so good. The device is small and easy to use. I believe it's worth the cost of having a safe charger that you can depend on.

Super fast shipping and delivery. Thr trickle charger I was using failed so I replaced it with this one. I haven't used it nuch yet but it was easy to use and the instructions were excellent. And it works just fine. My purpose in using it is to extend battery life.

Works as advertised, great especially for price. The fittings were the right size to connect to my battery. Now easy to charge by just plugging in. No longer have to take trunk apart to get to battery to charge. Thank you!

Update 22 June 2024: five down to three was too harsh. It was extremely inexpensive and served well for four years. After searching (endlessly) for an appropriate replacement, I ended up buying another MotoPower unit - their 1.5a version. I figure a device with a little more heft probably won't generate as much heat as this one did, so may last even longer; and it was barely more than what I paid for the first one!Update 19 June 2024: After almost exactly four years in service, The charger died. Wife smelled the acrid scent of burnt out electronics and alerted me to it. It was in use daily for all four years. A while after the narrative below, I had set up a Raspberry Pi to monitor the battery voltage and turn this on when it reached a certain threshold - the backend story is the 2018 Honda Accord has a nasty parasitic draw problem, so it was necessary to alway have it monitored and charged cyclicly. So it was powered on and off from a few times to maybe ten times a day. However, a charger like this is _not_ a complex device; exactly four years of service strikes me as 'planned obsolescence'. So I'm dropping the rating from five stars to three stars. It is not hard to build simple electronics to last decades. There's just no good excuse for a short life - other than to 'encourage' a new purchase.Here's my tale:After a couple of months of driving my car barely once a week during the COVID-19 isolation orders, my 2018 Honda Accord wouldn't start. Tried a jump start from wife's 2002 Honda Civic - still no go. yikes! Got out the decent quality multi-meter I have - less than 8 volts, from a 12V battery. Double yikes! Checked the electrolyte - whoa, one of the six cells had exposed plates. Well, that fairly well explains the very low volts. Topped it up to the line, then tried jump start again...yep, triple yikes.Well, I had plenty of time on my hands being furloughed, so I ordered this little unit. Inexpensive, but it made appropriate promises for what it can do, for what it costs. Ratings good. Some horrible though. Took the chance.At 800mA, this is not going to charge a 500Ah car battery quickly. I hooked it up and monitored the voltage for several days. Weather was rather warm, 80's to 90's F, and I noticed this little device getting pretty darned hot - too hot, in fact.Disconnected it and took off the back plate. Board very hot to touch, capacitor and transformer too hot to touch. Bad design! This thing needs to either be potted with a non-conductive heat sink material for full contact with the inside of the case, or the case needs vents. Period. That much heat will toast those components over time. True - I was asking the device for all it had - to charge a pretty deeply discharged 12V high amp capacity battery. Which isn't _per se_ its intended function. Still though.I decided to DIY. Took a drill and drilled four holes in the back plate, and two holes on each side, see photos. Pretty? Not on your life. Crude but fairly effective? Yes indeed, at least, it allowed _some_ of that heat to dissipate.Eventually there was enough charge to start the car, took it for a long drive, then hooked it up again to see if it would complete the full cycle - which it did after another day. It eventually hit the couple of voltage marks to go into absorption mode, then into float mode. Highly accurate too - 14.19v - still absorption mode. 14.20v - boom, float mode. Repeatable.For twenty bucks, it did what I wanted - and most importantly, what I _expected_ - unlike some of the reviews that complain it took days to charge their battery...well duh! It puts out less than an amp, expecting a fast charge from a slow charge device is just....dumb.That said - please guys - make the 'slotted' sides into real slots, to let some air flow through it. I realize it adds a little to the manufacturing costs, but people will get a longer life out of their (admittedly tiny) investment in this - and maybe fewer will die out in the field, eliciting bad reviews.As for me, I'm very happy with it - because it met my expectations.

When the product first arrived, it got here very quickly and arrived in a small box, after I opened it up, I realized how little it was and how convenient that would be to keep the batteries charged over the winter on TinderThe unit works automatically and flawlessly key notes to considerCompactEasy to useWorks on most batteriesUses little electricityHas a long cord to reach hard to get two places

Excellent product. Fully charged my dead battery. Charger is much better than I expected. Very well built. Fast shipping and great price.

I've grown up with Battery chargers that are basically the size of, well.....car batteries. After the last one went bad, I decided to try the new high tech world. This one is about the size of a the battery block on your laptop charger. And it actually worked great. It might take a little longer to charge, I'm not sure. But In my case, and time I'm charging a battery I'm always doing it over night, so it works great in that scenario. And it takes up so little space!

Initially the charger wouldn’t work. I unplugged it and plugged it back in and it started working and has continued to work. It keeps my battery on my atv ready to go. Size isn’t everything!

Son totalmente originales, funcionan muy bien para hacer una carga lenta a alguna bateria, lo cual puede ayudar a mantener la salud de la bateria, y como mantenedor de baterias funciona muy bien, siendo compacto no ocupa espacio y permite tener bien si se almacenan las baterias.Muy recomendable calidad precio

I charged the battery once , battery fully charged and then when i want to charge the battery again, the charger didn’t work :(

great

Es un buen producto, es compartible con el cargador original que traen las motos Harley Turing.

Easy to use and works as expectes
