Our Methodology

We drain-test each power bank from 100% to 0% while charging devices to verify actual capacity vs rated. We measure charging speeds with USB power meters, test passthrough charging, and evaluate build quality and portability. No manufacturer has editorial influence.

Frequently Asked Questions

How do you test power bank capacity?
We fully charge each power bank, then drain it from 100% to 0% while charging a known device (or resistive load). We measure actual energy delivered and compare to the rated capacity. Typical real-world results are 85–92% of the manufacturer's mAh rating.
What's the difference between mAh and Wh?
mAh (milliamp-hours) is capacity at a specific voltage—usually 3.7V for internal cells. Wh (watt-hours) = mAh × voltage ÷ 1000. Wh is more accurate for comparing different chemistries. A 20,000mAh at 3.7V ≈ 74Wh. FAA limits use Wh (100Wh max for easy carry-on).
Is passthrough charging safe?
Yes, when implemented correctly. Passthrough lets you charge the power bank while it charges your devices. We test for thermal behavior and stability. Anker, UGREEN, Baseus, and Shargeek models we recommend handle passthrough well. Avoid cheap no-name brands for passthrough.
Which power bank charges the fastest?
For output speed: Anker Prime 20000 (200W) and Anker 737 (140W) lead. For recharging the power bank itself: EcoFlow River 2 reaches full in ~1 hour via AC. Most power banks take 2–4 hours to recharge at their max input.
