What to look for in a portable battery pack

Battery type

Nearly all rechargeable power banks use lithium‑ion technology, which offers high energy density and no memory effect. Energy density has improved eight‑fold over the past 14 years.

Flying with portable batteries

TSA allows external batteries up to 100Wh in carry‑on luggage only. Some airlines now require power banks to be kept in clear view while in use. Check airline policies before traveling.

Capacity

Capacity is measured in milliamp hours (mAh). A 5,000mAh bank can partially charge a phone (50–75%), while 25,000mAh+ units can charge laptops and provide multiple phone refills. Real‑world efficiency averages around 60% due to heat loss and voltage conversion. For example, a 10,000mAh bank delivers roughly 5,800mAh to a device; 20,000mAh gives about 11,250mAh; 25,000mAh gives about 16,200mAh.

Wireless

Qi2‑certified wireless power banks provide up to 15W speeds with magnetic alignment. They are less efficient than wired charging but offer convenience. Newer Qi2 25W standard supports faster charging on iPhone 17 and Pixel 10 Pro XL. MagSafe and Pixel Snap technologies enable magnetic attachment.

Ports

USB‑C ports deliver faster charging than USB‑A. Larger banks often have multiple USB‑C ports with varying wattages, labeled in tiny print. In/out ports can both charge the bank and power devices. Always use a cable rated for the wattage you need. Built‑in cables are increasingly common and help avoid forgetting a cord.

How we test power banks

Each battery is tested by charging iPhones (11, 14 Plus, 15, 16), Samsung Galaxy S23 Ultra, iPad Air, and MacBook Pro from near‑dead to full (or until the bank dies). Devices are drained to between 0–5% before each test. Battery capacities of test devices are recorded for reference. This guide is updated regularly as new products are released.

Other power banks we tested

Selected alternatives that didn't make the final cut:

• Belkin Stage PowerGrip: 9,300mAh with a MagSafe wireless pad and Bluetooth shutter for photography. Slow charging but unique design.
• Anker MagGo for Apple Watch: 10,000mAh with built‑in USB‑C cable and pop‑up Apple Watch charger. Handy for Watch users.
• HyperJuice 245W: 27,000mAh, four USB‑C ports, fast charging. Similar performance and price to our laptop pick but fewer ports.
• EcoFlow Rapid magnetic power bank: 5,000mAh Qi2 magnetic charger with attached cable. Slower than Anker MagGo.
• Mophie Snap+ Powerstation Mini: 5,000mAh, premium build, but only half the capacity of the Anker MagGo for a similar price.

Power bank FAQs

What's the difference between a portable power bank and a portable charger?

The terms are interchangeable. All refer to a lithium‑ion battery that stores charge to refill smartphones, tablets, earbuds, laptops, etc. Power stations are larger units not allowed on airplanes.

Does fast charging ruin your battery?

Heat is the main enemy of battery longevity. Fast charging generates heat, but modern phones include heat shields, heat sinks, and software that slows charging when temperatures rise. EV studies show slight capacity loss from exclusive fast charging, but ambient temperature plays a bigger role. In practice, today's safeguards make any effect minimal.

Can you use a power bank for all your devices?

Yes, if the bank's capacity and ports are compatible. A 5,000mAh bank won't charge a laptop, but 20,000mAh+ can give a partial laptop charge. Devices with USB ports easily connect; devices with unique DC or AC ports may require special adapters or larger power stations.
