NEXPEAK NC215 15-Amp Battery Charger, 12V 24V LiFePO4 Lead Acid Portable Car Battery Charger 9-Stage Trickle Charger Smart Battery Maintainer w/Temp Compensation for Car Truck Lawn Mower Boat Marine

I’ve been using this charger to keep my 12Ah LiFePO4 battery, which powers my HAM radio setup, topped off, and I’m really impressed with its performance. The 15-amp output is more than enough to charge the battery quickly and efficiently, even when I’ve drained it quite a bit. I love how it handles the charge process smoothly and without issues, ensuring the battery stays in great shape.What stands out is how versatile it is—it's designed to charge both 12V and 24V batteries, so I know I’ll be set if I upgrade in the future. The charging process is fast but safe, with clear LED indicators showing the progress, which I find really helpful. The charger has several built-in safety features, including overcharge protection, which is a big plus for me because I don’t have to worry about damaging the battery while charging overnight.The build quality feels solid, and it has been reliable through multiple uses. It’s also surprisingly compact for how much power it delivers, which makes it easy to store and use even in a tight space. If you're using a LiFePO4 battery for your HAM radio or similar projects, this charger is a great choice. It’s efficient, easy to use, and gives you confidence that your battery will last longer. Highly recommend this for anyone looking for a dependable charging solution!

I've only used it a few times so far but I don't understand why some of these chargers cost 5 or 6x the price. I just bought this one for $25 shipped. It's fan runs all the time, but it sounds like a quiet white nose machine, hardly offensive.Display is very bright and easy to read. Watching the voltage and amp behaviors as it charges and gets near the end of the charge (volts go up, amps drop) everything seems just fine. Charges steadily at 15.5 amp until the last little bit (12v 100ah lifepo4 battery).Unit doesn't get hot, the cables get slightly warm to the touch but they're a little on the small side. I cut off the VERY cheap feeling clamps and replaced them with Anderson connectors into my diy battery station.My battery came with it's own 7A charger, plugs into the side with a 3 pin aviation plug. Marketing info indicated I could charge with that and charge with the top terminals at the same time and it absolutely does work. So now I'm charging at 22A for the low price of $25, crazy good deal.

For an inexpensive battery charger, it seems well made and works well. I have used it on both lithium and lead acid batteries successfully. It does take a few hours to fully charge a car battery.

Works great! Really like that is shows me voltage and current readings :-)My only complaint is how noisy the fan is. I intend to use this in my bedroom for my cpap battery.Good news, the fan does shut off once it goes into FUL mode.

I've been using this NexPeak 15amp charger for a week or so and I am very happy with it so far. I live off grid in northern VT (12yrs) and have many different batteries, various battery banks that need charging more so when the solar panels are covered in snowy winter conditions. Really can't beat this charger's very affordable price with it's 15 amp charging, large clear info screen, winter summer modes, etc. Also like that it's compact. The overall feel of quality is somewhat light weight & isn't super premium but again it serves it's purpose well & it's well priced IMO. Just ordered a second one.

I needed a new charger for my "many" batteries I have laying in my garage. I have used this charger on multiple batteries and it works very well. No issues and I would definitely recommend this charger. I would also buy this again if I needed another one. Its super easy to use and I like the colorful and bright display. God bless.

This little puppy really worked!!Got an old 2003 f150 runs perfect got new battery - still won’t start after sitting 5 days- worse in cold! Spent too much trying to find problem. It jump starts immediately - but want thr battery to stay fully charged. This said “FULL” when I hooked up - but then went to “TKL” trickle. I really didn’t know how to do it - I’m a grandma! - so left on overnight and the truck started up like brand new this morning!! It is plug in (my jumper is battery)- so I’m thrilled!Such a great price too!Highly suggest!! Trickle to get battery up instead of letting it drain then jumping!!

I was very happy with this charger the first few times I used it. The price, size, weight, graphics, speed, ease of use were all perfect. Until, one day after using this unit, the digital clock in my truck was off by 5+ hours. Didn't think too much about it. Just reset the clock and went on my way. Then one day I found this tidbit buried in the middle of a section of the instruction manual: "Charging the batteries with vehicles connected is not suggested, it may have potential damage to the car electronics during the desulphation stage". Logistically, it is not feasible for me to remove the battery to charge it. So, this product basically turned into a glorified paper weight overnight. So my review went from an enthusiastic 5-star, to a mediocre 3-star, to one star since I will not be using this charger again. What a shame. Hopefully Nexpeak can fix this issue. A Noco or Battery Tender charger is in my future.
