Works as advertised/ easy to use
This charger actually puts out the 20 amps as advertised. (Or really close to it). It can be manually switched to charge lifepo4, lithium, and a variety of lead acid batteries.The common complaint of too short of a cord seems to have been resolved as this unit has a 10’ power cord and 3’ leads to the clamps. I tested all 3 power levels and each performed within 0.4 amps of the power that was selected.The fan is loud but it’s doing it’s job.Unfortunately there is no provision to mount the unit to a wall but it does come with ring terminals if you want to hard wire it to your battery or bus bar.All in all I was quite happy with the way it functions.Hopefully a true 25a - 30a charger will be available soon as this 20a is a bit small for charging 100-200ah batteries.

5.0 out of 5 stars A good value for what it can deliver
Reviewed in Canada on April 18, 2024
Size: 20 AmpVerified Purchase
Easy to use - select a type of battery to charge and you are good to go. Works well with my 12V 100aH LifePO4 battery, it takes about 5 hours from 0% to full charge. It does deliver 20Amp but the amperage will fluctuate depending of the battery's SOC. The charger and the charging cables don't get hot. But, the fan is loud when kicks in - it will eventually stop when the battery is almost full.

One thing you should be aware is that the display will say "OFF" if you unplug and plug the charger to an outlet after the battery is fully charged. Apparently, this is normal according to the seller. I thought something was wrong with the charger when I see it at first.

It’s a smart charger. I had a new battery but something was wrong with it I knew it wasn’t old or sitting in a corner for a long time so I bought this and it had battery take a full charge then I put it on repair mode and it fixed my issue of not enough power to start vehicle. Now it’s starting every time again. I’m so glad to have bought this as a replacement battery when it’s new wasn’t a route I wanted to take right away. What a product!! It’s like I have a Brand New Battery now. Would recommend to my friends and family as well as anyone else interested.

5.0 out of 5 stars very good charger when you read the instructions
Reviewed in Canada on April 4, 2024
Size: 20A ProVerified Purchase
Initially I could not get significant amps but pressing the button took it from 5A to 10A to 15+A. Another press takes it to pulse charging to recover a sulphated dead battery.

I bought this to charge a large lifepo4 (840AH) 12V battery bank on my boat. It will add about 350AH per day which is what I wanted.

I am now a happy camper!

4.0 out of 5 stars Works as described. Fan runs a bit noisy.
Reviewed in Canada on April 6, 2024
Size: 20A ProVerified Purchase
Got it earlier than my new LiFePo4 battery. started charging at HIGH option. it recogonized as 12v and started charging at 20A then gradually went down to about 15A. It could stop charging at FULL. While when I measured the voltage, it is about 13.7v, not knowing how much AH the battery would have. Fan sounded a bit louder, but seems normal. Temperrature increased to no more than 39c and Display is clear and easy to read. Weight is said to be 1200g in manual. Would check how long the battery would run next week.

Not a bad product, does it's job. Only thing I don't like is when you hook the battery up it just charges right away and you can't just check voltage before charging. Other then that it does tell you charge status while running and it's for about every battery made

5.0 out of 5 stars Great charger for 6V/12V lead acid batteries

The media could not be loaded.
 I was referred by a battery technician to buy a charger like this since the one I needed to “break in” my lawn mower and generator batteries, and when I take them out for winter time, use the charger to maintain the batteries.

I bought one and it is more than I expected. Very simple to use and it works great. It charged my riding lawnmower in less than an hour.

As per the specs this charger is designed to charge 6V/12V lead-acid batteries, that have 2 Amp Current max, also has a big nice LCD digital display, easy to read the voltage and charging process.

I looked at other chargers but this is a great value and works really well. Don’t hesitate and buy one!

4.0 out of 5 stars If you consider it a 15 amp charger, it's great. 20 amps is unrealistic
Reviewed in the United States on January 13, 2024
Size: 20 AmpVerified Purchase
This works really well on Lithium Iron Phosphate batteries. BUT you only get 20 amps out of it for a very short time, then it gets warm & throttles back to 15 amps. It's the same if I charge 1 battery or two in parallel, so it's not an acceptance limitation on the part of the batteries. It's a characteristic of the charger.

This charger has some great features. It shows percentage charge & amp hours delivered. Unfortunately, once the charge is complete, the amp hour display disappears. I wish they made other versions that were bigger.
