TOPDON Jump Starter and Battery Teste

There's nothing worse than getting stuck with a dead car battery, especially if you're busy and on a schedule. You can't always rely on someone nearby having jumper cables, either. And you definitely don't want to spend the money to get a professional if you can help it. That's why being self-reliant and getting your own portable jump starter is so important. As soon as your car battery dies, you can get it up and running almost as quickly with a jump starter. After browsing through the bazillion models available on Amazon, I went for the Topton JS3000, which looked like something substantial that can have enough power to start my old F-150. And, I wasn’t disappointed. The jumper comes in a very nice hard shell style transportation/storage case, and contain everything needed to be ready to use it. Even the USB power block, which is often missing on other models. Talking about USB, this battery jumper devices have USB ports as well, and we often use this in our garage as an oversized battery bank as well when not used to jump start anything, to charge phones and the like, so it’s very useful in all sorts of emergencies. Using the device was very easy really. After being sure it has a full charge, I just plugged it to my truck’s battery, and it immediately detected it and turned one automatically. All I had to do was crank the engine, et voilà, the truck started right at the first try! Once fully charged, I can store this device in my truck, and forget about it for six months or more, until the next time it’s needed. They do however need topping up occasionally, especially if they get very cold or very hot repeatedly. So, something to keep in mind to avoid having a battery jumper that will have a depleted battery, just at the most needed moment. There are other little details that make the JS3000 easier to use. It turns on with a single short press to the power button, as does the embedded flashlight, which cycles through multiple on and emergency flashing cycles. Other units I owned in the past required assorted long and confusing sequences of presses, which might protect against turning on accidentally, but was a hassle when I actually needed to use it. Like every other lithium jump starter, it has of course a reverse polarity detection, alerting you if you connect the clamps to the wrong battery terminals. Keep in mind that the best time to think about shopping for a portable jump starter is not when you’re stuck by the side of the road with a dead battery. Compact, affordable, and easy to use, the latest lithium-ion chargers like this one could be a life saver, and are also small enough to fit in a glove compartment or under the seat, yet it can start your car (or truck) without jumper cables or waiting for help. Definitely a recommended purchase, which I am happy with.
