Buying a Portable Charger For Smartphones

A portable charger for smartphones can help you keep your phone, tablet and other gadgets going when you're out of reach of a power outlet.portable charger for smartphones Some have the power to recharge your smartphone multiple times and are small enough to fit in your pocket, while others are a bit bigger and have more ports so you can charge multiple devices at once. Some also support fast wireless charging, which is a big selling point for some people.

Capacity, shown as milliamp hours (mAh), is the best indicator of how much power a battery pack will have and how many charges it can deliver.portable charger for smartphones If you want to make sure your phone will always have enough power to last through a night out, look for one with at least a 10,000mAh rating. If you need to charge more than a single device and can spare the bulk, try a 20,000mAh power bank that will recharge most recent phones several times.

Many power packs include connecting cables, and you'll find some have a built-in USB-C port so you can use your own cable if necessary. Some also show your remaining power level on a screen. If you have an iPhone, it's worth checking whether the connector in the package is MFI certified, so it will work with your phone.

Some of the most popular models on the market are small, lightweight and easy to carry in your bag or briefcase. We like the Anker PowerCore Slim for its Goldilocks size and capacity: It's not too small to be unwieldy, but it has enough juice to fully recharge most smartphones twice. Some of the more advanced options feature a USB-C port that supports fast charging, so you can top up your laptop or phone at up to 20 watts.

We also recommend the Baseus Magnetic power bank, which has the second highest power-to-weight ratio of our top picks. It's also a bit more attractive than some of the other options and has a flat shape that fits nicely in most handbags. It has a 10,000mAh battery inside and can recharge an iPhone 15 just short of two full charges, or a Galaxy S23 Ultra three-and-a-half times.

The Mophie MagSafe Battery Pack is another big-name option, but it's a bit more expensive than the Anker model we recommended above and its magnetic attachment doesn't work with all MagSafe-enabled cases or Android phones. It does, however, come with a "snap adapter" that sticks to the back of your phone and allows it to charge wirelessly at speeds up to 7.5 watts, and an extra USB-C port that you can plug in your own cable for faster charging. It also has a small LED indicator that lets you know when the battery is almost empty. It's available in a range of colors and finishes. It's also the only power bank on this list that can charge an Apple Watch.
