If you ever get worried about your car battery dying, having a weak charge or just acting kinda funny, this two-in-one emergency device will calm your mind. It can charge your car, boat, motorcycle, trailer or lawn mower battery in hours or maintain its power levels just by clamping wires and pressing a few buttons. One reviewer says, “It’s smarter than most mechanics.” Plus it’s loaded with safety features— one user says you can even touch the clamps together and nothing will happen, though we don’t recommend testing that theory — has an easy-to-read screen, and right now, it’s nearly 50% off. That’s a steal for something that can save your butt from getting stranded in a random parking lot or a chilly battery making you late for work.

This compact battery charger plugs into a wall outlet for power and only requires connecting the red and black clamps to the appropriate battery nodes. After that, you just press some buttons. Its LCD lets you view your battery’s voltage or current percentage, and it has two buttons to automatically juice your battery, depending on if it’s a 3A (for power sports vehicles and lawnmowers) or 15A (cars and boats). The device won’t overcharge, and lights on its corner indicate whether it’s charging, maintaining a power level or if your clamps have been placed in reverse order.

Note that this device isn’t used to jumpstart cars — you’ll still need cables for that. It can still revive a dead car battery, though it’ll take longer than a jumpstart.

Emergencies aside, this is a nifty preventative tool, too. You can keep it on hand or in your garage to charge a battery overnight if it’s low or use it to check your current battery level. You can also charge a battery at a specific voltage, so if you’ve got a battery that’s had a jumpstart, you can charge it to 50% life, so you won’t need a second jumpstart later. It can also “maintain” a battery you don’t often use, like a car you don’t drive that hasn’t been turned on in a while. And furthermore, cold weather drains batteries, so using this product as a battery maintainer ensures yours won’t drop in power level if it’s too frosty outside. Because of its auto shut-off feature, the device won’t overcharge once it’s to capacity, and you can leave it connected to your car battery indefinitely.

If you’re looking for a handy device to add to an emergency kit, consider this battery maintainer/charger while it’s at a deep discount. Read on for promising reviews from reviewers who’ve had their battery woes solved by this device.

I let my batteries go to zero on my travel trailer, so I removed them and hooked them up to this charger and in 24 hours they were back to 100% and the charger went from charging to float… never trust the ac at a storage facility… this charger is light weight and simple to use and user friendly….” — Patricia Sherffius

“Size and portability. Easy to use to charge a car, truck, tractor or ATV battery. A great value for your money.” — Linda

“I have a 2007 4-door Jeep Wrangler that doesn’t get driven much at all anymore since I have a newer one, so the battery drained down to about 4.2V, which was barely enough to give some lights/status, but wouldn’t start the Jeep of course. I connected that battery in parallel with a lower-than-spec 12V lawnmower battery, and was able to get them both up to spec with no difficulties. Charger has easy to read status indicators so I could quickly see where the charging process stood. Wouldn’t hesitate to buy this again if I needed one.” — Julio Santos

If you don’t drive your car very often. Especially In the winter. This Is the thing to get. Always keeps your battery fully charged. It’s a charger and a Maintainer. Worth the money.” — Gary

Hooked it up to a paddle boat with a small electric motor with battery. I charged it for 6 hours. It also has a safety light instructing if you hooked the cables backwards. Thats good if you never did it before. It also has a full charge indicator.” — Fran

“Hi – I have been using this charger for a few years to charge a 35AH SLA battery. I charge it up whenever bad weather is coming, so I have something to charge cell phones and run over-the-air TV so I can get weather – like in a hurricane. I also take this battery on weekend camping trips so I can charge cell phones and run my laptop. The charger works reliably, and gets the battery – an ex pert pow er – to its full capacity. This charger does the fancy stuff. It will not overcharge. If you accidentally touch the clamps to each other, nothing happens. It is fairly fast, at 6a – so, the 35ah gets topped off in a few hours. 6 x 4 = 24.” — P.J. Rowan

“Easy to use. Charged my car in about 5 hours” — pamela ladd
