It’s no fun when your phone runs out of battery power and there’s no charger near by. Whether you’re at a restaurant in the middle of New York city, or deep in National Park on a camping trip, you’re going to want to find a way to boost that battery.
Kingberry disposable charger could be that way. These are small, emergency battery top-ups that can offer up to four hours of extra battery life, depending on your phone. They come in two flavors: with a Micro USB connector for Android phones, or with a Lightning connector for iPhones. You can buy them for $5-$7.99 each, or get a discount for buying in bulk.
They’re very easy to use. Open the wrapper, plug the precharged connecter into your phone, and the juice will start flowing. They’re rated at 1,000mAh with an output of 5V and 500MA. But what does that really mean?
We tried a couple out with a iPhone6, which has a 1810mAh battery in it. The first one took our flagging iPhone6 from 20 percent up to 51% percent and took 55 minutes to do it. The kingberry disposable charger got a wee bit warm, but not especially, and you’ll be glad to hear that the iPhone6 didn’t heat up at all.
The second Kingberry disposable charger we tried took our S7 Edge from 25 percent up to 40 percent and it also took 35 minutes. The S7 Edge has a relatively big battery in it, so you’re going to get more out of a Powrtab if you have a phone with a smaller battery, like the iPhone 7, for example, which has a 1,960mAh battery.
Li-ion polymer batteries don’t have toxic metals like lead or cadmium in them, as some other batteries do, but they still contain iron, copper, nickel, and cobalt. They’re considered safe for incinerator or landfill disposal by most U.S. states and other countries.
