Anker Nano Power Bank (30W, 10K, Built-In USB-C Cable) vs UGREEN Nexode 145W 25000mAh 3-Port Power Bank
Which should you buy? Our verdict on both, pulled from our full The Power Banks Worth Buying (and the 'Mega-mAh' One to Skip) comparison.
For most people the Anker Nano's built-in cable, accurate display, and pocket size make it the easy default. Step up to the UGREEN 25K only if you need to charge a laptop or multiple devices on the road.

Anker Nano Power Bank (30W, 10K, Built-In USB-C Cable)
Buy itThe best everyday carry: a pocketable 10,000mAh pack with its own cable and a screen that never lies to you.
- Built-in USB-C cable, plus a second USB-C port and a USB-A port, so you never dig for a cord
- Color display shows battery percentage at a glance
- Refills itself to 50% in about 45 minutes and is pocket-sized
- 10,000mAh is roughly 1.5-2 phone charges, not a multi-day pack
- The secondary USB-A port tops out slower at 22.5W

UGREEN Nexode 145W 25000mAh 3-Port Power Bank
Buy itA do-everything travel brick that fast-charges a laptop and two phones at once.
- 25,000mAh with 145W output can meaningfully charge a MacBook Air, not just phones
- Three ports (dual USB-C + USB-A) power a laptop and phones at once
- UGREEN labels it airline-friendly (25,000mAh works out to roughly 90Wh, under the 100Wh carry-on cap), and a TFT display shows remaining charge, voltage and current
- Heavy and bulky compared to a 10K pocket pack
- No built-in cable, and it's overkill if you only ever charge a phone
