Does everything that battery tender does and more. Including having an led screen and better spring clamps.

I’ve had this for a couple of weeks and seems to be working well. Easy hookup, LCD works well in the cold (some don’t). The charge is slow so don’t expect a quick charge. The only real small gripe is that the ring cable to put on the battery is rather short, on my Subaru it won’t reach to come out the grill so I need to pop the hood to attach/detach (might be able to find another route once it warms up).

My car has a short someplace and the battery seems to loose it charge a few days of not driving it. This little tiny device keeps my battery going and hasn't failed me yet!!! So glad I got this and so happy it works amazingly keeping my battery charged!

this 4 Amp Battery Charge work excellent it maintainer the battery 100% all the time I very very happy

Purchased it to charge vehicle that has been sitting in the garage for several weeks at a time and used for short driving distances. Took nearly 18 hr to fully charge car battery, which I had more or less expected after a recent stall prior to purchasing it. Car starts up normally, without hesitation now.

Very nice Battery Charger. Really like the terminal rings that can be put on battery and left there for future charging purpose. Saves the hassle of uncovering the battery and attaching clamps. Charged my battery to 100%, reconditioned it and then went into "trickle-maintain" state. Excellent.

Everything worked as advertised. It was very easy to hook up, it recognized the 12 v batteries, it went through the different stages, and charged four car batteries each taking 6-8 hours. I showed my daughter how to use it in the first one, and she used it on the others on her own.

Got this for my father-in-law and he really likes it

I purchased this to keep my 1926 Model T's 6 volt battery maintained the winter in storage. So far it has work great.

With Covid my car was spending more time in the garage as we weren't getting out as much. Worked great to keep my automobile battery in good shape.

Got this on deal of the day for half the price. Wish I would of bought more. Use them on my atv boats and cars

I use this to keep my camper battery charged over the winter. Works great and the battery is ready to go when I need it.

Love this charger---we use it to keep our RV batter topped off and it's excellent

WORKS AS ADVERTISED NO COMPLAINTS FROM ME. ABSOLUTELY

It's been working great. I have it on an old tractor that sits outside. I only use it for snow removal in Minnesota. The battery typically dies in the below zero weather. With this I haven't had any issues and it fires right up.

Simple to use and it works great. I wall mounted the charger in the garage and attached the wires to the battery and zip tied the wires in place under the hood.

Nice product to have to keep your batteries Charged and ready to go when you need them

Charger has not been used yet. It was purchased proactively for use when eventually required.

A new style to me,but easy to use and does the job

Works good on my dad's dodge truck. And fairly quick.
