Frequently Asked Questions

What is the best power bank for laptops?

The Anker 737 PowerCore 24K and Anker Prime 20000 are our top picks for laptop charging. The 737 offers 140W output and 24,000mAh capacity, while the Prime 20000 delivers up to 200W for the fastest laptop charging in a compact form. Both support MacBook Pro and most Windows laptops.

How much capacity do I need in a power bank?

For phones only: 10,000mAh gives 2–3 full charges. For phones + tablets: 20,000mAh is ideal. For laptops: 24,000mAh or more. Note that actual usable capacity is typically 85–92% of the rated mAh due to conversion losses.

Can I bring a power bank on a plane?

Yes, but with limits. FAA allows power banks under 100Wh in carry-on (no limit on quantity). 100–160Wh requires airline approval. Over 160Wh is generally prohibited. Most power banks under 27,000mAh at 3.7V fall under 100Wh. The EcoFlow River 2 (256Wh) cannot be carried on flights.
