The Best Power Banks for Your Phone, Your Laptop and Your Next Flight

This is the power bank to leave in a bag and forget about until you need it. Its 10,000mAh is the size that covers a long day: EcoFlow says it charges an iPhone 17 to half in 19 minutes, and by the 0.65 rule of thumb it holds close to two full phone charges. It weighs no more than 230 grams (8.1 ounces) and measures 3.5 by 2 by 1.5 inches.

The cable is why it beat the other 10K banks we looked at. A 2.3-foot USB-C cord pulls out of the body and winds back in, so there is no cable to forget at home and none to untangle. That cord and the bank's two ports make three outputs, and the strongest gives 45W, enough to fast-charge any current phone and to keep a tablet going. A display shows the charge left as a number rather than four dots.

The near-twin is Anker's Nano Power Bank (10K, 45W) with the same retractable-cable idea, the same 45W and the same 30W recharging. Anker's is a little smaller and lists for about 40 percent more. Against the INIU SnapGo Air below, you give up magnetic charging for a cable that works with any phone, earbuds case or tablet.

If you carry an iPhone 12 or later, a magnetic bank is the easiest kind to live with: it snaps onto the back of the phone and charges it with no cable at all. The SnapGo Air is the one to get. It supports Qi2.2, the newest version of the wireless charging standard, which lets an iPhone 16 or 17 take 25W without a wire.

It is half an inch thick and weighs 6.9 ounces, lighter than the EcoFlow above with the same 10,000mAh. When you want speed, the short USB-C cord attached to the bank gives 45W, and its two USB-C ports let it charge three things at once: the phone on its back and two more by cable. A small display shows the charge left.

Read INIU's fine print before you buy. The 25W rate needs an iPhone 16 or later updated to iOS 26, and leaves out the 16e and 17e; older iPhones charge from it at the slower speed they support. Wireless charging also loses more energy than a cable, so expect fewer refills when the phone rides on the magnet. Anker's MagGo Power Bank 2 Pro does the same 25W job with a cooling fan, a stand and a bigger screen, at twice the list price.

Half the capacity buys a bank you stop noticing. The Nano 5K is 0.34 inch (8.6 mm) thick and weighs 4.3 ounces, a little over a third of an inch on the back of an iPhone. Its 5,000mAh is roughly one top-up for a current phone by the 0.65 rule: enough to get from a dead afternoon to bedtime, not enough for a weekend away.

It charges magnetically at up to 15W, the Qi2 rate, and by its single USB-C port at up to 20W in either direction. Anker says it keeps the case below 104°F while it works, which matters for something pressed against the back of a phone in a pocket.

Pick it over the SnapGo Air when size matters more than capacity. It is 2.6 ounces lighter and about a third thinner, but it holds half as much and charges an iPhone 16 or 17 at 15W rather than 25W.

A laptop changes what a power bank has to do. It needs 65W or more through a single port and several times a phone's battery, and the RAPID 25K covers both: 100W from a single output and 90 Wh inside, which EcoFlow says is one full charge for a MacBook Pro or four to five phone charges.

Those outputs are two USB-C ports and two USB-C cables built into the body: a 26-inch (67 cm) cord that retracts and a 10-inch one that doubles as the carrying strap. With two in use the total is 170W, enough for a laptop at full speed and a phone beside it. The 100W input matters as much. With a 100W charger it refills to half in 26 minutes and to full in 80, so a layover is long enough to win most of it back. A color screen shows the charge, what each port is drawing, temperature and battery health.

At 580 grams (1.28 pounds) it is a bag item, not a pocket one. Anker's Laptop Power Bank (25K, 165W) is the same design down to the two cables and the 100W input, at about the same list price; it is 15 grams heavier and adds a USB-A port, which the EcoFlow lacks. Buy the Anker if you still charge anything with a USB-A cable.

This one is for people who work from a 14- or 16-inch laptop on the road and want as much power as the rules allow in a single bank. Its 26,250mAh is 99.75 Wh, a quarter of a watt-hour under the 100 Wh line above which the FAA requires your airline's approval. Anker says it holds 0.8 of a full charge for a MacBook Pro (M4).

Each USB-C port gives up to 140W, and the total across both and the USB-A port is 300W, which Anker says keeps two MacBook Pros running at full speed. Anker says it charges a MacBook Pro (M4 Pro) to half in 27 minutes. Recharging is the other headline: through both USB-C ports at once it takes 250W and reaches half in 13 minutes, provided you carry chargers that can supply that much. A screen and Anker's app show what each port is doing and let you cap the output.

At 600 grams (1.32 pounds) and 6.3 by 2.5 by 1.5 inches, it takes up a little less room than the EcoFlow RAPID 25K and holds about 11 percent more energy, but it lists for almost twice as much and has no built-in cable. Buy it only if 100W is not enough. A MacBook Air, or any laptop that came with a 65W or 100W charger, gets its full speed from the EcoFlow.
