Use the Real Deal
The charger that your gadget comes with is ideal for the job. It’s designed to work well with the gadget’s battery. However, things happen. You may lose your charger or inadvertently damage it. When that happens, you probably aren’t too worried since you can run out and purchase a cheap replacement when that happens.
Just any old charger isn’t going to cut it, however. These inexpensive replacements aren’t designed to help your battery function at its top performance, so your gadget will ultimately suffer. You risk reducing your device’s lifespan when you cut corners and buy a cheap replacement. So do yourself a favor and get a high-quality replacement.
