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.

I love the manual controls of the voltage mainly and the amperage. The auto features are recognizable and proper. Using 2 at the same time works well also unlike other fully auto chargers. I wish these were around years ago would have prevented alot of failures. They are working great for final float absorption charging a 9 batt lead acid bank for off grid. They run properly with a small genny saving alot of Ga$. Thank you, I even shopped India marketplace for this style in the past with virtual no responses. 5 stars

positives are Works on AC power that comes from a generator. I have a battery bank of 6 volt batteries wired for 12 volts. With this charger it will charge the batteries to the desired volts and won't cut off at 12 volts like most chargers do. I was able to get the battery bank up to 12.7 volts according to my mppt solar charge controller. at the same time a multimeter said the battery's where at 12.5 and the charger it self said 13 volts. either way it got the bank up to around 80 % charge fairly well and this was charging at around 10 or 11 amps. very happy with this purchase so far but its only been one night of charging. Negatives The unit stays powered up when hooked up to battery bank when generator is off. this wouldn't be a problem except the fan element in the charger runs even when it is not charging.

This product is nice. It's very easy to use and upon preliminary testing it works well

Quality control is terrible. The red connector cable fell out of the back of the charger and the black connector cable was stuck into the back through the fan vent between two fan blades. When I took the housing cover off, I found that neither cable was connected! The cables had been cut (and very cleanly)! It arrived inoperable and I never knew it. I spent $180 buying a new battery for my boat because this machine couldn’t charge my old battery (or so I thought). Turns out, this company just ships broken chargers. DO NOT BUY! And yes, I did reconnect the wires myself and was able to make the charger work. Not the point. What if I hadn’t opened it up and looked inside to see the cut cables? This isn’t a DIY kit and I shouldn’t have to fix defective products. EDIT: After reading my review, the seller reached out and offered a full refund. I commend their team for trying to make things right. I will also repeat that I was able to use the charger (once the cut wires were reattached) to bring a completely dead battery back to full charge. I am happy with its capabilities.
