What to look for in a battery case

You might think that choosing the right battery case for your phone is to choose the battery case with the maximum capacity, but it’s too big to fit in your pocket and you always go home It’s a surefire way to do it. Choosing the right charging case results in the right balance between battery capacity, size, and price.

If you’re just looking for a battery case to put in your bag when you need it, you might want to get a portable charger. If you can’t put it in the charging case, it doesn’t make sense to buy one that’s molded to fit your cell phone. Otherwise, there will be space left that could have been used to install more energy cells. With that in mind, find a battery case that actually fits in your pocket without adding too much weight.

Another problem when choosing a maximum capacity battery is that it is often the only feature. All of the largest battery cases we’ve seen sacrifice fast charging and Qi charging capabilities to store more energy. The latter feature is useful when you want to keep track of your phone’s charge and charge both your phone and battery case wirelessly at the same time.
