⚡ Quick Answer
The Anker PowerCore 10000 (~$26) is the best power bank for most travelers. 10,000mAh, TSA-approved, charges an iPhone 2.5x, and fits in any pocket. Want USB-C PD fast charging? Step up to the Anker PowerCore III 10000 USB-C (~$26).
Why a Power Bank Is Non-Negotiable for Travel
A dead phone in an unfamiliar city is a genuine problem — no maps, no translation, no hotel confirmation, no way to call for help. Airport outlets are scarce and usually occupied. The solution costs $26 and fits in your pocket.
The Anker PowerCore 10000 ($26) charges an iPhone 2.5 times from zero. That's two full days of heavy travel use. At 6.2oz it fits in a jeans pocket. Anker has been the dominant power bank brand for a decade because they just work — over 100,000 Amazon reviews don't lie.
How to Choose Power Bank Capacity for Travel
mAh = milliamp hours = how much charge the bank holds. Here's what the numbers mean in practice:
- 5,000 mAh — charges iPhone 15 once. Pocket-sized. Good for day trips or as a backup.
- 10,000 mAh — charges iPhone 2.5x, Android 2–3x. The sweet spot for most travel.
- 20,000 mAh — charges phone 5x or charges a tablet. For long-haul travel with multiple devices.
USB-C vs. USB-A: if you have modern devices (iPhone 15+, any recent Android, newer laptops), get a USB-C power bank with Power Delivery — it charges significantly faster. The Anker PowerCore III 10000 USB-C ($26) handles this.
TSA Rules for Power Banks
Power banks must go in carry-on luggage — never checked bags. TSA limit is 100Wh (about 27,000mAh). Most travel power banks are well under this. The Anker PowerCore 10000 is 36Wh — no issues.
mAh — What You Actually Need

| 20,000mAh | ~5x | Long-haul, multiple devices |
| 26,800mAh | ~7x | Max TSA-allowed; heavy use |
