If you are getting shocked off this item your circuit is improperly grounded or ungrounded.

I gave this five stars because it has basically been my power supply / charger for my (usually) 23’ off grid camper. That’s hard use and it’s been doing it over a month now and doing it well. Once fall arrived with shortening sun hours and many cloudy days in a row my solar and batteries started struggling to keep up. I needed just enough extra power to keep the furnace running 24/7 without dragging down the batteries. It consumes very little power. I measured 1.94A at 120V (232W) while it was charging 14.9V at 9.4A (132W) for about 60% efficiency. Both the amps and the volts are adjustable with rotary knobs. This is convenient for many applications. If you were just holding a battery over winter, for example, you probably wouldn’t want to charge it to 13.8 volts, you’d just want to maintain the 12.8V full charge at say, 1A. This unit can do that! In my case, with the furnace or other items are consuming power, I want to charge at 13.2 or 13.4. If it’s cloudy I could charge at/to 14.4 to 14.6 and get some absorption charge (granted I get great solar charging on sunny days, so I don’t need a big battery charger. However, FYI 10A is too small to charge 300Ah or 600Ah of batteries. That’s not what this is made to do.) Right now it is set to 13.2V and 10A. As the battery reaches the set voltage the amps automatically reduce. The unit is displaying 13.2V and 1.2A and the fan speed is reduced. And yes, the fan is variable speed. If the unit is inactive because the battery has reached the set voltage the fan is stopped and the amps are zero. As the battery voltage declines, due to load or self discharge, the amps begin to rise and the fan begins to run. Turn the volts all the way up and the fan will go to max speed. The charger never has gotten hot, and the fan output has never felt warm. While the alligator clips and their wires also stay cool, I do have a complaint with the wire size- very thin and likely to be damaged. A 10ga wire would be a great improvement. Or at least something thicker and more flexible. Yes I’m using it for an unintended purpose but it’s been great. It’s living up to its price point. Great little charger! PS: all the poor reviews because people don’t know how to charge a battery? Pretty foolish to leave a bad review when the product is fine and the reviewers don’t know what they are doing. I’d buy again and recommend to others as well.

UPDATE: the company reached out to me after my initial review. the sent me a replacement. i updated my review because when this charger works it is great the review would have been higher if it didn't take a poor review to get their attention, I tried to reach out to them before I left the review as seen below. Hope this is the last update I have on this charger. I have it hooked up to a low battery now. received this to charge a battery, worked great for that battery. I didn't need it for about 7 months. hooked it up to the dead battery same as instructions say to do it. lights and gauge flickered and then it stopped working. reached out to the manufacture thru their website to see if they offer any type of warranty on their product. well that was a month ago and still no reply from them. I did purchase another charger as I need a charged battery and this time I spent 1/4 the amount and got my battery charged.

It's a TOY, Works great and accurate but don't try to do anything other than trickle charge a small battery 2 amps or less or it dies!!! It died charging my motorcycle battery that was at 12.4 volts and it died before getting it charged fully to 12.6 or so.

This charger is so tiny! It almost feels strange and criminal that it can do what it can actually do. I needed a charger for an electric scooter which uses two 12V batteries in series. I wanted to be able to charge either both batteries together at 24V but with the option to charge each battery individually if I needed to do so. To make things even more complicated, I could be faced with 7, 9, 10, 12 and 15Ah capacities! That means that for optimal charging and battery life, I would want to be charging from 0.7 to 1.5A, respectively for all of those different battery options. I couldn't find another charger that could give me all of those exact options! The fact that this charger was only about $20-30 more than the "fast charger" that is standard for this scooter, it was a literal no-brainer. Also, reading some of these Amazon reviews where the charger was "not working," some of them may have been simple problems, like the Amp setting being set to zero when starting the charging process, or having both clamps connected too early, or by simply not using the recommended value of 14V+ for charging a 12V battery. (...try 14.3 or 14.4V) THIS CHARGER ROCKS Edit: Now that I've been using this charger for a while, it's even more impressive now. I had a 12V 10Ah battery that I'd completely left for dead; nothing I threw at it would do anything to the battery. I decided to connect it to this charger, and set it to 17.5V @ 2.5A and in less than a minute, the battery started to take a charge! Very impressive. I backed down the voltage after about 10 minutes and the battery started slowly taking a charge.
