Get straight to the top tech—no junk, just the best.

Smartphones are becoming larger and more powerful, and their batteries have also increased in capacity, with some of the best models now exceeding 6,000mAh. Most users can get through a full day of use on a single charge, although intensive use may shorten that time. If you're having a particularly busy day, you might find yourself needing to recharge your phone, either by plugging it in or placing it on a wireless charging pad.

However, finding a charging outlet isn’t always feasible, especially if you're on the go or far from any power source. This is where a portable charger, battery pack, or power bank becomes invaluable. By connecting your phone to a portable charger, you can recharge your device without being tied to one location. Whether you prefer a large, robust charger that can power your phone for days or a slim power bank that easily fits in your bag for a quick charge, there’s a suitable option for you. Here are some of the best portable chargers we've discovered.

Frequently Asked Questions

Are portable chargers worth it?

The answer generally depends on how often you travel. If you're a frequent traveler (or heavy commuter) and tend to go for relatively long spells between visits to a normal charger, portable chargers definitely are worth it. While some of the heftier chargers can be fairly pricey, they're still a good purchase if you really need to be on your phone while away from a wall socket. At the same time, many portable chargers with smaller capacities are available for reasonable prices, so even infrequent voyagers may find they're worthwhile.

What is a good capacity for a portable charger?

The answer to this question depends on how many devices you intend to power while you're away from a wall charger. If you're using a phone and a tablet, then a portable charger with 10,000mAh or more may be worthwhile. Some people need portable chargers that offer at least 100% of their smartphone's battery, while others need even more or less. It's best to find out the battery size of your device and choose accordingly. For some people, even a smaller portable charger that offers 2,000mAh (around 50% of the average flagship smartphone) is enough, while some people who travel extensively will need at least 5,000mAh, 10,000mAh, or even more.

How long do portable chargers last?

Most good portable chargers should last for at least a few hundred charges before beginning to deteriorate. Longevity varies among devices, so it's best to do your research and check with a charger's manufacturer (or seller) before making a purchase.

Can you bring a portable charger on a plane?

You can bring your portable charger onto an airplane. However, remember that any portable chargers must be taken as carry-on luggage, and should not be checked in with your larger suitcases and stored in the hold of the plane. This holds for the vast majority of airlines operating today. If in doubt, call your airline's customer service number to confirm their policies beforehand.

Where can I buy a portable charger?

You can buy portable chargers from pretty much the same outlets as smartphones, tablets, and other devices. Apple and Samsung's official websites stock a number of portable chargers, while you can also find plenty from online retailers such as Amazon, Walmart, and Best Buy.
