    5.0 out of 5 stars Lots of technology for the money.
    Reviewed in the United States on December 5, 2024
    I bought these to maintain the battery on a propane fueled generator. The generator is back up power for a water well pump that is remote from our home. These little devices will maintenance charge, cycle and charge either 12 volt or 6 volt batteries. It come with two attaching cables. One with alligator clips the other has ring terminals. Both connect with a polarized molded connector. Both of good quality. The electronics are enclosed in a molded plastic case with lighted indicators for which mode it's in. It also has a meter to show percentage of charge. All and all an impressive piece of gear for the money. I don't know about longevity but function is quite good.

    5.0 out of 5 stars Love my new Automatic Battery Charger/Maintainer
    Reviewed in the United States on December 10, 2024
    I bought 4 of these for keeping my batteries in tip top condition during winter storage and they work great! I love that it has a charging mode as well as a maintaining mode, and both run on a preprogrammed smart system. It has a mode button to select the charging style, and a nice blue backlight to make it easy to display the charging current and voltage. I think these will keep my 12 VDC car and lawn tractor batteries in great shape when they are just sitting during the winter months.

    5.0 out of 5 stars No More Dead Batteries
    Reviewed in the United States on May 17, 2024
    I bought this 2-pack of NEXPEAK chargers specifically for my 2004 Honda Element, a weekend warrior that kept suffering from a dead battery. Let me tell you, these chargers have been a lifesaver!

    Now, I can confidently park my Element for weeks without worrying about a jump start every time I need to make a quick run. It's a huge relief!

    The STD mode with automatic shut-off after a full charge is fantastic for everyday maintenance. But what really impressed me is the trickle charge mode. It keeps my battery voltage at a perfect 13.6V, ideal for long-term storage.

    This charger isn't just for cars! It's become my go-to for reviving my portable generator battery too. Power outages are no match for me now!

    The price is unbeatable, especially considering the features. Plus, it's incredibly user-friendly. The display is clear and bright, and it comes with all the necessary accessories for different battery types.

    If you're tired of dealing with dead batteries, the NEXPEAK charger is a fantastic solution. It's versatile, easy to use, and very affordable. I highly recommend it!

    5.0 out of 5 stars Worked great on both 12v and 6v
    Reviewed in the United States on December 19, 2024
    I bought multiple of these for my collection, they worked great on my 12v vehicles, including the ones with dual batteries. I also hooked it up to a vehicle with a 6v positive ground. These recognized each battery toes and started maintaining their charge. Works great on both my gas and diesel vehicles

    5.0 out of 5 stars Reliable and easy to use
    Reviewed in the United States on November 17, 2023
    These tenders are super user friendly and do a great job. I have them hooked up to two banks of two deep cycle six volt batteries (hooked up parallel to make 12 volts) for my motorhome as well as my boat's deep cycle batteries. For the price they do just as well as my NOCO battery tender that are easily twice the price. Would definitely buy again if I ever need another tender. They even do a decent job charging, they just take a long time as they're low amperage and not really designed to legit charge a battery but they'll do it. I also like the screen that even works in really cold weather.
