Best Portable Chargers of 2026: Power Banks That Keep Up With You

Capacity vs. Portability

Portable charger selection comes down to one trade-off: capacity versus size. A 10,000mAh power bank fits in a jacket pocket and charges an iPhone 16 Pro Max twice. A 26,800mAh bank will charge a laptop but weighs nearly a kilogram. For most travellers, 10,000–20,000mAh hits the sweet spot. The other critical spec in 2026 is maximum output wattage — 30W charges phones quickly but won't charge a laptop; 100W handles phones, tablets, and most USB-C laptops.

Best Overall: Anker 737 Power Bank (PowerCore 26K)

The Anker 737 at $99 is the most versatile power bank we've tested. Its 140W maximum output charges a MacBook Pro at full speed via the 140W USB-C port, while simultaneously charging two additional devices via the 30W USB-C port and USB-A port. The 26,800mAh capacity provides 3–4 full charges for a smartphone or 1.5 charges for a 14-inch laptop. The digital display showing exact remaining capacity is a small but genuinely useful addition.

Best Slim: Belkin BoostCharge 10K

At 22mm thick and 182g, the Belkin BoostCharge 10K slides into the same pocket as your phone. It charges at 15W via USB-C, which is fast enough for a full iPhone charge in about 2.5 hours. For travellers who carry light, this is the power bank that disappears into your bag until you need it.

Best for iPhone: Anker MagGo 10K

The Anker MagGo 10K attaches magnetically to the back of any MagSafe-compatible iPhone, providing a clean, cable-free charging experience. At 7.5W wireless output and 15W USB-C wired, it's not the fastest charger, but the convenience of snapping it on and forgetting about it makes it the best commuter companion for iPhone users.

Pros

  • 140W output charges MacBook Pro at full speed
  • 26,800mAh handles phones and laptops
  • Digital display shows exact remaining capacity
  • Charges three devices simultaneously

Cons

  • Heavy at 668g — not a pocket power bank
  • Charging itself takes 3 hours at 140W
  • Large size may not fit in some laptop bags

Our Verdict

The Anker 737 is the best all-round power bank for travellers who need to keep laptops, tablets, and phones charged. The 140W output is genuinely laptop-grade.

Frequently Asked Questions

Can I take a 26,800mAh power bank on a plane?
Yes, power banks up to 100Wh (approximately 27,000mAh) are permitted in carry-on luggage on most airlines. They must go in your carry-on, not checked baggage. Check your specific airline's policy as some have stricter limits.
How many phone charges does 10,000mAh provide?
A 10,000mAh power bank delivers approximately 1.8–2.2 full charges for a modern smartphone (iPhone 16 Pro Max has a 4,685mAh battery, Galaxy S25 Ultra has 5,000mAh). Real-world capacity is slightly lower due to conversion inefficiency.
