Buying a Portable Charger

When you need to charge your phone without an outlet, a portable charger is the best solution.phone portable charger Power banks, as they're sometimes called, are batteries that supply a regulated voltage to your device through a USB port. You plug the USB end of your cable into the power bank, then the lightning end into your phone. The power bank will then charge your phone at a rate that depends on its capacity and the power needs of the device itself.

Portable chargers come in all shapes and sizes, from small sticks with a few hundred mAh to heavyweight battery powerhouses with 20,000mAh or more.phone portable charger They can also differ in how fast they charge and whether or not they have multiple USB ports.

The most important factor to consider is the charger's capacity, which is usually written as a four- or five-digit number with mAh (milliamp hours) following it.phone portable charger The higher the number, the more recharges you'll be able to get out of it before it runs out of juice.

A good guideline is to find a power bank that can charge your phone at least twice before running out of energy. But if you need to charge other devices, such as tablets or GoPro cameras, you'll want to look for a bigger number.

Besides the size and charging speed, other factors to consider are whether the power bank has more than one USB port and what kind of output each of them will have. Most have two ports, and the most popular have fixed outputs of 2 x 2.4A for smartphones or 1 x 2.4A for tablets. This means that if you're using two smartphones at the same time, each will get a full charge in about three hours.

You might also want to think about getting a portable charger with a flashlight, which can come in handy when you're trying to use your smartphone in the dark or when it's raining outside. And some models have extra features, such as a built-in fan that will cool the device down when it's being charged.

There are few things more frustrating than arriving at an airport or other unfamiliar location and finding that your phone has run out of power. It can be difficult to navigate the area to find an outlet, and if you're lucky enough to find one, you might have to wait while others take their turn. A phone portable charger will give you the freedom to explore and get around in places where there are few outlets, or simply when you're away from home and can't easily charge your device.

Our top pick is the INIU 10000 mAh portable charger, which beat out our previous top pick, the Anker PowerCore Slim 10000, in part because it has two USB-A output ports compared to the Anker's single port. We found that the INIU's charging times and speeds were close to the Anker model, but the second port gives you the flexibility to charge a tablet while charging your phone or even power another device while you're at it.
