Nothing’s worse than having a low car battery and figuring out how to take your ride to the mechanic. (Actually, something is worse: tow truck fees.) Rather than tinkering with that low or potentially dead battery, take a preventative measure instead. This smart battery charger, for example, can juice your battery up as needed — just charge the device, clamp it to your vehicle battery and it’ll automatically adjust your battery power. Perfect for emergencies, this compact tool can fit in your car or charge up in your garage so you can adjust (not jump!) your battery when you need it. And right now, at Walmart, you can nab one at a deep discount for just $19. That’s 62% off its regular price of $49.99!

This battery charger maintains your current charge by auto-adjusting according to temperature and voltage as needed. That means in winter, it’ll give your battery a boost when it’s cold out, and in summer, it’ll prevent it from overloading. It has a memory function, so it’ll default to the previous charge setting when it was last powered on, so you won’t have to fumble with its options. It also has an LCD screen to show you your current battery status, charge voltage and charge current, plus a winter and summer mode to increase or decrease charge as needed. Numerous reviewers also say they’ve used this little device for lawn mower batteries, bikes and motorcycles.

“I had a car whose battery died,” says a reviewer named mahes, “[and] instead of taking it to auto shop, I just [charged it] at home!”
