What to Look For in the Best Portable Battery

When it comes to portable batteries, you have to be really selective since you do not want to get one that charges your devices really slow, or even worse, that does not charge it at all. That is why you have to make sure you buy a high quality one that works whenever you need it.

Battery Charger

That being said, take a look at the following features to determine the most important aspects a portable battery should have.


The first thing you want to look at is the compatibility. Not all portable batteries are going to work for all devices. If your device is not compatible with the battery, then it will not work.

You also have to know how much power your device needs to be fully charged. If the battery cannot completely charge your device, it is not really going to do much good. So, make sure you get a battery that has at least enough power for a single full charge.

Compatibility of batteries

Another aspect of compatibility is having the right connectors for your devices. If your battery does not have a cable that connects to your phone or tablet, you could be in the same position, anyway.


Another important aspect is how durable your battery is. You have to make sure that it is going to last a long time even under strenuous use. Think about the circumstances where you will probably to use your device and make sure you choose something that is going to be okay under those conditions.

Durable portable battery

You have to buy one that will not break easily if you drop it, for example. You also have to make sure it is going to stand up to a lot of recharges. Just like anything else you plug in, your battery is only going to work for a period of time. Make sure that is a long time.

Size And Weight

You should select something compact and easy to carry, and not every battery pack is small and fits in your pocket. Some of them are much larger and may require carrying them in your backpack. In order to make the right decision, just choose a small and lightweight battery that matches with the devices you will charge.

Additional Features

While you might not think about them, there are actually some additional features associated with battery packs.

Pocket chargers

A few of them come with different connectors to be attached to different devices; some others have different currents available. A couple of them have a flashlight or a hand warmer; and some others even let you know how much battery power is left with little level indicators.
