If your smartphone is constantly running out of battery, a portable power bank (also referred to as a ‘portable charger’ or a ‘portable battery’) is pretty much your only solution short of getting a new one. There are a zillion different options out there, but if you want to charge your smartphone we suggest buying one that is small enough to fit in your pocket. Check out our top picks below.

This PowerCore Sim checks most of our boxes. It’s super thin and can easily fit in your pocket. Two, it has a fast and powerful 20W USB-C port that’s capable of charging your iPhone 12 to about 50-percent in 30 minutes. And it’s 10,000mAh capacity is enough to charge whichever smartphone you have several times over (and it’s actually more than many other super slim portable batteries on this list). This is a great universal portable battery, however, if you have an iPhone you might want to look at something with an integrated Lightning cable like Mophie’s powerstation plus mini (below).

The best thing about the powerstation plus mini is its integrated charging cable with Lightning and micro-USB connections. It means that you don’t have to remember to bring a charging cable, which is the biggest hassle and the thing that’s most likely to get lost or broken. Throw in the fact that for some reason Amazon is selling it for under $10, and it’s a no brainer buy. The only downside is that its 4,000mAh is barely enough to get any smartphone back to 100 percent.

Mophie makes a wide variety of portable power banks and this powerstation with PD is one of its best all-around options. Its 10,000mAh capacity is enough to completely charge your smartphone twice over and it charges via USB-C, which is the same connection as most new-age laptops and Android smartphones. It also has a 18W USB-C output port with Power Deliver (PD) so it’s able to fast charge your smartphone.

The PowerCore Slim is a 10,000mAh portable battery that’s capable of charging most of the latest smartphones tw0-and-a-half times over. It has two input charging ports, micro-USB and USB-C, so it’s versatile in the way you can recharge it. Its only output port is a USB-A 2.0. The catch is that it only comes with a micro-USB charging cable — no USB-C cable or wall adapter — which is why it’s so affordable.

The powerstation plus is a larger version of the powerstation plus mini, which is our “best budget” pick. It’s a 6,040mAh portable battery (compared to the mini’s 4,000mAh) and holds enough to charge your iPhone a little more than once over. It also has two color features that are specific to iPhone users. One, it has an integrated Lightning cable that hides nicely into its side. And two, it charges via Lightning, too, which is convenient. Normally $80, you can get this for significantly less right now.

RavPower 1000mAh Compact Portable Charger

RavPower is another one of our favorite makers of portable chargers. This pocket-sized option is nice because it supports Power Delivery (PD) and can charge most smartphones faster than other power banks. It also has 20-watt USB-C input that supports PD, so you can recharge it really fast, too. It comes with a USB-C to USB-C cable, but no wall adapter.

The Charge Stream Powerstation Wireless is unique because it’s portable power bank and wireless charging pad. It has a 10,000mAh capacity that’s similar to many other options on this list, but it can wireless charge any smartphone that supports Qi-wireless charging. So you don’t even have to fuss with a cable if you don’t want to. It has an additional USB-A port if you want to use a charging cable.

The PowerCore+ Mini is a lipstick-shaped portable charger. It only has a 3,350mAh capacity, which isn’t enough to fully recharge most smartphones, but it’s a good option for people looking for a cheap and really pocketable charger. It needs a micro-USB to charge.

Belkin’s 10,000mAh portable charger has a built-in stand that’s perfect for people who like to watch videos on their smartphone while it charges. And since the stand is retractable, it doesn’t make the charge any bulkier. There are two out ports, one USB-C and USB-A, so it’s capable of charging two devices at the same time.
