Who this guide is for

Portable chargers for phones, tablets and laptops, chosen for real capacity, charging speed and size. We focus on what each pick does best, what it typically costs and who should skip it.

How we chose

We compared manufacturer specifications, documentation, warranty terms and typical US prices, then gave each product a clear Buy, Consider or Skip verdict. Our verdicts are based on this research, not on lab testing.

What to look for

  • Capacity: 10,000 mAh fills most phones about twice; 20,000 mAh or more suits laptops and long trips.
  • Output: phones need 20W to 30W, while laptops usually need 45W to 100W over USB-C.
  • Airline rules: the FAA allows power banks up to 100 Wh in carry-on bags, never in checked luggage.
  • Size and weight: a bank you leave at home because it is heavy does not help.

Buying tips for smart shoppers

Buy power banks from the brand’s official Amazon store or listings sold by Amazon, because counterfeit chargers are common. Check the watt-hour rating if you fly, and look for UL or similar safety certification.

Frequently asked questions

How many times will a 10,000 mAh power bank charge my phone?

Usually about twice for a modern phone, because some energy is lost as heat and battery conversion.

Can I take a power bank on a plane?

Yes, in your carry-on. The FAA allows lithium power banks up to 100 Wh without approval, and they are not allowed in checked bags.

Is it safe to leave a power bank charging overnight?

Quality power banks from reputable brands have protection circuits, but it is still best to charge them on a hard surface and unplug when full.

Best power bank: what to know before you buy

The best power bank depends on what you charge. In 2026, the Anker 737 Power Bank is our pick for laptops thanks to its 140W output, the Anker Nano Power Bank with a built-in cable is the best everyday carry, and the INIU 10000mAh is a reliable backup for under $25.

Think in watts and watt-hours, not just milliamp-hours. Watts tell you how fast a power bank charges, and watt-hours tell you how much energy it holds and whether it can fly. A 10,000 mAh bank holds about 37 Wh, while a 24,000 mAh bank holds about 86 Wh, which is still under the 100 Wh limit for carry-on bags.

Phones charge happily at 20W to 30W, so any modern USB-C power bank works. Laptops are pickier. A MacBook Air or a Windows ultrabook usually wants 45W to 65W, and bigger laptops want 100W or more. If your power bank cannot deliver enough, the laptop will charge slowly or only slow its drain.

Skip no-name bargains with huge capacity claims. Fake ratings, missing safety circuits and counterfeit listings are common with power banks. Anker, INIU, UGREEN and Belkin all sell through official Amazon storefronts, and a power bank from a known brand costs only a few dollars more.

Across the power banks we cover, typical prices run from $17 to $149. Store prices change often, so treat these as typical ranges and check the current price before you buy.

Capacity: 10,000 mAh fills most phones about twice; 20,000 mAh or more suits laptops and long trips. Output: phones need 20W to 30W, while laptops usually need 45W to 100W over USB-C. Airline rules: the FAA allows power banks up to 100 Wh in carry-on bags, never in checked luggage.

Also worth a look is the Anker MagGo Power Bank, usually $59–$89, which is best for iPhone MagSafe users. Its standout feature is snap-on Qi2 wireless charging; the main trade-off is wireless charging wastes some energy as heat. The INIU Portable Charger 10000mAh 22.5W typically costs $17–$25 and earns a Buy verdict. Buy it if you want an inexpensive backup battery for a phone in a bag or glovebox. Skip it if you want fast laptop charging or a premium build.
