I bought 2 of these and liked them so much I bought 2 more for my other cars. I have several cars, and they do not all get driven enough to stay charged, especially in the winter. These little trickle chargers allow me to keep the batteries topped up so that they are all ready to go whenever needed. These come with the option to hard wire to the battery terminals or use alligator clips. The charging unit stays very cool, so no worries about keeping them plugged in for weeks at a time. Great quality for the price.

This is my second purchase I love these chargers for my adventure bikes when not in use they're durable long-lasting and affordable safe to leave on full-time never let your batteries go bad again

Somewhere, someone actually wanted to build a very good battery charger AND maintainer, and they actually did it. First: this is not a "jump start" high current charger. Second: if your battery needs a miracle, take it to church, because this wont fix it. Third: This is the best battery charger I have ever seen, especially for the price. I rarely write reviews. I am also equally rarely impressed with low cost made-in-China consumer goods. When I got this charger, I did not expect to be impressed. For fun I put a voltmeter and a current meter on it expecting to be unimpressed and to hate on it... To my shock and amazement, a pleasant surprise. They got this charger EXACTLY right. in short: In the video's above you can see the charger applying constant current of ~900mA then backing off and measuring voltage, all the way up to 14.5 volts-offo-the-charger, and then switching to 33mA of constant current. (note that if this were used in a car with large capacitors attached to the battery it may go in to the trickle charge mode a bit early, but this is not likely with most farm / atv / classic cars, and would certainly be avoided by pulling the battery terminal when you charge it) A few days ago, after throwing away my 3rd Harbor-Freight "trickle charger", (They last about 1 year then then seem to die, and their internals are is nothing more than a poorly regulated 14.5 volt constant voltage source with very little current) I started asking myself, "why don't you just go ahead and build your own charger... If i had the time, THIS charger would have been what I would have spent hundreds of hours perfecting. This charger is a smart charger that is actually smart. When you attach it to the battery, it measures the voltage on the battery, and if it is below 14.5 volts, this charger then applies about 0.9 Amps ( constant current mode, NOT dependent on battery voltage) for 10 seconds, then dis-connects the charge for 1 second, re-measures the battery voltage, and if it's disconnect-voltage is under 14.5 volts, it starts this cycle over and over again. This is an excellent way of truly top-off charging the battery, (1 Amp is not too shabby if you have more than a few hours). Once the 14.5 volt threshold has been crossed, the charger then goes in to a mode where it switches to constant-current of 35 Mili Amps, and stays in the 35MA mode until the next time that the charger is dis-connected from the battery. I know this is a bit technical for most non-battery nerds, but suffice to say, if you have a car / tractor / ATV that sits a lot more than you use it, this is the charger you want for it. It -WILL- charge a discharged battery fairly quickly (5-20 hours depending on battery size and how dead it is). It charges at a rate of 1-am-hour, so take your battery size and do the math.. It will not kill your battery with over voltage, and it will not kill your battery by completely disconnecting the charge from it, leaving it to slowly die offline. If I were to build a charger, this is what I would have come up with. Update: Left it charging over night, It is still testing the battery ever 10 seconds, and keeping 35mA going in to it. I also unplugged the charger, and measured to see if the charger itself would present a parasitic load on to the battery, which (in the case of the Harbor Freight charger) will kill the battery in the case of a long-term power outage. GOOD NEWS: this charger has ZERO parasitic load if the main power fails, so it will not kill a good battery in the case of long-term power outages. Again, this is an excellent charger.

Recently purchased, so no real feedback available on function just yet. Unit was packed well and appeared to be functioning normally when plugged in and connected to battery. Appreciate the different options available for connecting to end devices.

I live in Japan. Long Story Short Version - After WWII, Japan received help from both the USA and England in rebuilding their electrical power infrastructure. The result is that parts of the country run on 50 Hz while other parts run on 60 Hz. I happen to live in the 50 Hz zone, so when I import electric-powered goods, it's hit and miss what will work. Case in point, my Chamberlain garage door opener. It sat for 6 years without being used because it never worked properly. I went through everything I could think of (including days on the phone with Chamberlain [warranty voided automatically]) but could never make it work. A few months ago, at a friend's house, he opens the garage door with a Chamberlain! His house is almost 100% off-grid. What he discovered was ... when he switches over to grid-power, he opener also doesn't work. The answer was in his main power, with was run by an inverter that outputs 110V@60 Hz. NOTE:I also tried a step-up converter to go from 100V to 120V, but that didn't do anything. My solution was to buy an inverter (120V@60Hz) and hook it up the same way my friend did, which worked. The final piece of the puzzle was 'how to keep the battery fully charged'. Ideally I could run the trickle charger from the inverter and have the electric charger equivalent of a perpetual motion machine, however ... it doesn't work. So, I'm running both a solar panel charger (during the day) and the trickle charger (at night) and it works brilliantly. SIDENOTE: With the inverter running 24/7, it draws down just enough power overnight that the inverter will not work in the morning. (For anyone who's interested, the REAL problem is my battery doesn't have enough Ah. At only 28 - the smallest battery I could find - it's not enough. If I double the Ah [which I did for a test - wife was gone for the weekend, so I pulled the battery out of the Honda Fit and connected it to the inverter battery with jumper cables] it lasts for 3 days without a charge. And I'll bet I cycled the opener at least 10 times a day.) I bought this charger figuring that I wasn't losing much $$ if it didn't work correctly, and if it DID work, but the charger burned out quickly I would just buy another, stronger charger. So far, no complaints at all. It's a great value and with the ring connectors, it was a snap to hook up to my system.

Perfect way to main maintain your battery during the cold months

Excelente producto, lo compré para revisar un par de baterías que no cargaban

simple to use, no bells and wistles, down and dirty charger., I liked it but it died after a few months

It's not charging at all....seems some problem in the product ...
