Rexing - Master 1.5A Smart Battery Charger – 6V/12V Automatic Maintainer & Trickle Charger – Lead-Acid & Lithium

Ordered the Rexing N1 trickle charger on September 16th, 2026, and had Best Buy deliver it to my house. I reviewed all the modes and tried it on my 2026 F-150, which has an AGM battery. The instructions were understandable, and the unit attached without any problems. I like the fact that it has different modes (12V, 12V AGM, 12V Lithium, and 4V however, I doubt I will ever use the 4V or 12V Lithium because I don’t have those batteries). Newer vehicles have AGM batteries; this thing is a lifesaver! If I had any recommendations, it would be to have a power cord on the unit., Without it, you must plug it into an extension cord if you don’t have an electrical outlet close to the point of use.

One of the best features of this charger is the cord that is over 8' long. It makes it convenient to charge a vehicle without putting the charger under the hood or leaving it exposed to the elements. I only gave it 4 stars since while the battery clips are removable there is no terminal lugged pigtail to permanently connect it to a battery included with the charger. When I attempted to use the charger with an existing pigtail that I have on one of my cars the connector is backwards from the common pigtails for this purpose. The hot (positive) lead on the pigtaiI would stick out without being shrouded by the connector. I did like the versatility of the charger and that it can also be switched to charge Lithium batteries as long as the battery has a charge controller and can be used to charge 6 Volt and AGM batteries. This will be great for charging up my outdoor power equipment where I clip the charger directly to the battery or giving my vehicle a quick charge by pulling up to my garage door and clipping the charger to the battery.

I have bought rexing dashcam and jump starters before and their quality amazes me. They are far better than other generic brands. This battery charger is priced reasonably and useful for charging auto and other similar batteries. You will not have to go to auto zone and leave the battery there overnight to charge. Very compact in size and easy to use.

It is easy to use and works great. The included clamps connect easily to the battery terminals, and the clear LED indicator lights let me know exactly what’s happening at a glance. It’s great for keeping my car battery going, especially when they sit unused for a while. Overall, a simple and convenient battery maintainer that does the job well.

I own a number of different brands of battery chargers and maintainers and use them quite often. When I tried this Rexing unit for the first time, I connected it to an auto battery that had not been charged for quite awhile. I anticipated it would struggle with it but the next day, it was fully charged. The battery continues to be maintained very well since then. This automatically detects the battery status, adjusts for output due to the battery condition and goes into a maintenance mode and prevents overcharging. It also will work for 6Volt and 12Volt Batteries and has a selector for different types of batteries whether they are AGM, SLA, lead-acid, or lithium. It will also work for motorcycle and lawn tractor batteries too. I really recommend this nice unit!
