NEXPEAK NC201 10-Amp Battery Charger, Smart Trickle Charger 12V 24V Car Battery Charger Fully Automatic Maintainer Desulfator w/Temp Compensation for Car Truck Lawn Mower Boat Marine Batteries

Worked great! The repair mode worked exactly as advertised; left it on overnight & the next morning, my 5 year-old 12V SLA battery worked fine, for powering up my DuroMax generator. Pretty good deal for only $28; a new battery would cost twice that. Minor downside - the short cord lengths: 32" for the AC cord and 24" for the charger cables. I messed up & didn't properly plan for this Winter storm; the stores were sold out of new batteries. I found this on Amazon, with same-day delivery, and figured this was my best option. Worked out just fine.

I can’t put into words how valuable this little >$30 tool is. It’s saved over 3 batteries for myself and friends with its “Repair” function. It can take a while for the cycle to be complete maybe an over night thing (it may even take a day) when you’re trying to revive a bad battery but hey, it beats having to pay over $200 for a new one. It works perfectly, easy plug and play. Display is easy to read, I do recommend at least skimming over the manual to avoid any issues.

When hooked to a battery that may have a small load on it the charger will detect a reduced voltage and start charging again and keep the battery topped up. This is not the case for many which simply shut off and require either a disconnect and reconnect or a power cycle in order to start charging again. The first of these I have put in service has been in continuous use since December of 2024. The load on the battery is about 1 amp. It has a fan which only runs when the charger is charging.

I purchased this battery charger specifically to charge my AGM starter/accessory battery on my boat. I have a NOCO dual charger to charge the two batteries for the trolling motor, but wanted to be able to simultaneously charge the boat battery during multi-day fishing trips. My requirement was good quality, low cost, and 10A charging capability. This fits the requirements. I modified the battery cables to remove the clamps and install an SAE power connector for quick attachment to my battery from outside the boat. The wire diameter seems to be on the small side for 10A, but it should not be an issue due to the relatively short length of the cable. Compared to the NOCO charger, the wire diameter is much thinner and the cable is much shorter, which makes it a little inconvenient, but it is still (barely) long enough for my application. The AC power cable is also quite short, but an extension cord fixes this deficiency. I like the feature that it will indicate voltage and state of charge when you connect it to the battery, even without connecting it to AC power. This is useful for a quick evaluation of the battery state. Overall, I like the size, functionality, and 10A charging capability. The short cables are not an issue for my specific application, but may be too short for other applications.

Works great. Have been using it for awhile now and always works

Good trickle charger for maintaining a charge on a battery that is being stored for a period of time. Keeps it ready to go. I use it for my generator, tractor and vehicle batteries.

A small unit that does a great job. Was having issues with the car battery losing charge. Wouldn’t hold charge for more than 2 days. Used the trickle charger and has helped a great deal. Car starts every time now.

This unit has a handy screen which shows useful info like Amps and Volts. This unit is unsuitable for my application due the design issue of putting 21" clamp cables on it. The cables are too short for me to place the unit inside my engine under the hood and charge the battery. The unit ends up being right on top of the battery upside down to get the clamps to reach. I pinged Nexpeak and was told the unit was not meant to be outside in variable environmental conditions. It is designed to be in a climate controlled environment, such as a closed in garage. I live in GA. We don't have many garages. Most houses have carports, like I do. Its the same as being outside, and merely keeps the rain off you until you can get into your vehicle. Heat / humidity fluctuates which will eventually cause the unit to fail. I will have to hook up the unit and run it 24-72 hrs to top off the battery, then unhook and bring the unit inside out of the weather. Its below freezing right now at night, so this, and probably most other units will not last long outside. Since this is a 10A unit, it has a fan, probably because it gets hot running at 10A. This simply is too limiting and will not work for me. Its being returned. I will look for longer cables and easy detach so I can move the unit inside and out, and close the hood. Painful and not what I was looking for. You cannot plug this unit in and leave it all winter like the description states.

Al conectarlo se ha puesto en modo error y no deja camabiar a ningún otro modo de carga, es más, el botón mode como si no existiera. Y no es la primera vez que uso este tipo de cargadores. Totalmentre decepcionado y una pérdida de tiempo total. Lo he devuelto.

Very easy to use and does the job.

Not the best, but it does the job for sure. Wish the cables were longer.

Does the job. After 4 months of my car sitting idle, I could not turn it on. I used this charger to charge my car battery, and after an hour my car was able to start. Amazing product. The setup was simple—it's literally plug and play, DIY with no mechanic needed. The wire length is short, though, so you might need to use your own extension cable, but it's not a big dealbreaker, to be honest. To my surprise, it charged pretty fast. I wish I had found it sooner. A must-have product for people with cars that sit in the garage a lot.
