Some portable chargers also have a flashlight function that’s useful in case of emergency, but remember that using the flashlight will use stored power.

Most people usually have some kind of battery-operated technology at their fingertips, but there aren't always outlets within easy reach. Whether you're trying to stay connected on a camping trip or can't find an empty plug in a crowded airport terminal, a portable charger will provide you with the juice to revive your electronic device. Charge your portable charger like you would your phone and, depending on its capacity, it will provide you with at least enough power to top up your phone's battery. The following is a brief guide to finding the right portable charger for your needs.

Considerations when choosing portable chargers

Who can benefit from this electronic accessory?

People who can benefit from investing in a portable charger include frequent travelers, people who are always on their phones or laptops, lovers of the outdoors who want to phone access at all times, people in emergency situations where recharging via an outlet is impossible, and people who own old devices with quick-draining batteries.

What devices do you need to charge?

What do you carry around most often that seems to run out of battery? Laptops and smartphones require different amounts of juice to recharge. If you've got a slew of power-hungry electronics in your backpack or briefcase, you'll need a high-capacity charger.

How long will you be away from a traditional power source?

If you're heading out for an extended camping trip or have a phone with a quick-draining battery, you should consider a portable charger that can store a lot of power.

Portable charger features

Capacity: The capacity of a portable charger is listed in milliamperes per hour (mAh). A larger number means the device is capable of storing more battery life. Greater capacity allows for more charges of a single device or the ability to charge bigger electronics, such as a laptop.

Size and weight: Most portable chargers are small enough to stuff into a purse or backpack, and some units are compact enough to slip into a pocket. Choose a charger that you find comfortable to carry around.

Charging time: There are two charging times to consider: the time it takes to charge the portable charger itself and the time it takes to charge your electronic devices with the charger. Charging times for the units themselves vary somewhat, but most portable chargers restore the battery life of other devices quickly.

Ports: Some portable chargers have two or more USB ports so you can charge multiple electronics at once.

Battery indicator: Most portable chargers have an indicator that displays how much power is left in the device. When charging your device, the indicator lets you know when it's fully charged and ready to use.

Pass-through charging: If you need to charge your portable charger and your devices at the same time, you'll need a unit that's capable of pass-through charging. Not all chargers are equipped with this ability, however, but it's a nice feature that will most definitely come in handy at some point.
