Our Picks
1. Anker 737 Power Bank, best overall
The 737 is the power bank that does it all. Around 24,000mAh of capacity, high wattage output that charges laptops, phones, and earbuds at the same time, and a smart digital display showing exact battery percentage and charge speed. Owners love that it replaces multiple chargers on trips. It stays under the 100Wh airline limit, so it flies in your carry on.
Pros: charges laptops and phones together, huge capacity for its size, informative smart display, airline friendly. Cons: heavier than pocket banks, premium price, the display is small to read in bright light.

2. Anker Nano Power Bank 10K, best pocket power bank
The Nano 10K is the bank for people who hate carrying things. About 10,000mAh in a package not much bigger than a lipstick, with a built in USB C cable so there is nothing extra to pack. It fast charges phones at up to 45W, which is rare at this size. Owners buy it for daily carry and short trips where every ounce counts.
Pros: tiny and genuinely pocketable, built in cable, fast 45W charging, great for daily carry. Cons: 10,000mAh means about two phone charges, not enough for laptops, the built in cable is short.

3. INIU Portable Charger 20000mAh, best value
INIU has built a reputation for giving you a lot of milliamp hours for the money, and this 20,000mAh bank is the sweet spot. It charges two devices at once, supports fast charging protocols, and owners consistently praise its reliability at a price well under the big brands. For travelers who want capacity without the premium, this is the one.
Pros: excellent price per milliamp hour, dual device charging, slim enough for a day bag, reliable brand reputation. Cons: slower top speed than flagship banks, no smart display, the finish shows fingerprints.

4. Baseus Blade 100W Power Bank, best slim design
The Blade is shaped like no other power bank, a flat slab that slides into a laptop sleeve or document pocket. With 20,000mAh and 100W output it charges laptops properly while staying thin enough to disappear in a bag. Owners who travel with a laptop and hate bulky bricks love this form factor.
Pros: unique flat shape packs beautifully, 100W output for laptops, digital battery display, premium feel. Cons: the flat shape is awkward in a pocket, pricier than boxy rivals, 100W needs the right cable.

5. Anker MagGo Power Bank 10K Slim, best for iPhone
If you carry an iPhone with MagSafe, the MagGo snaps onto the back magnetically and charges wirelessly while you use the phone. No cables, no fumbling. The 10,000mAh slim version also charges wired through USB C at up to 30W. Owners call it the most convenient way to top up on the move.
Pros: magnetic snap on charging, doubles as a phone grip, also charges wired, slim profile. Cons: iPhone only for the magnetic feature, wireless charging is slower than wired, magnets add a little weight.

How to Choose
Start with capacity. About 10,000mAh covers a phone for a day or two, while 20,000mAh and up handles multi device trips and laptops. If you travel with a laptop, look for 60W or higher USB C output. Everything under 100Wh is airline approved for carry on, which covers all five picks here. Built in cables are a small luxury that saves real packing hassle.
The Verdict
For most travelers, the Anker 737 is worth it. It is the only bank here that truly replaces your wall chargers on a trip, charging a laptop, phone, and earbuds at once with capacity to spare. If you travel light and just need your phone alive, the Anker Nano 10K disappears into a pocket and costs far less.
Frequently Asked Questions
Can I take a power bank on a plane?
Yes, in carry on luggage only. Power banks are banned from checked bags. Anything under 100Wh is approved, which includes every bank in this guide.
How many phone charges is 10,000mAh?
Roughly two full charges for a modern phone, after conversion losses. A 20,000mAh bank gives about four to five.
What does 100W output mean?
It means the bank can fast charge power hungry devices like laptops through USB C. Phones need far less, usually 20 to 30W.
Do power banks lose charge sitting unused?
Slowly, yes. Top yours up the night before a trip, and recharge it every few months if it sits in a drawer.
