Building a one-cable travel kit? I pulled together the essentials here: Best USB‑C Rechargeable Travel Essentials (2026).
Quick take: If you want a travel-friendly power bank that can actually run (and fast-charge) a USB‑C laptop, the Anker 737 Power Bank (PowerCore 24K) is one of the most sensible “big-but-carryable” choices in 2026.

Most power banks are designed for phones first. The moment you try to top up a MacBook, Surface, or USB‑C gaming handheld, you find the limits fast: not enough wattage, not enough ports, or an output profile that’s “technically USB‑C” but painfully slow.
The Anker 737 Power Bank (PowerCore 24K) is the opposite: it’s built to deliver laptop-class USB‑C power (up to 140W max total output) while still being something you can throw in a bag. It’s not tiny. But it’s practical.
What it is (and who it’s for)
- For: frequent travelers, commuters, creators, and anyone who regularly drains a laptop + phone in the same day.
- Not for: minimalist EDC setups where you only need one emergency phone charge.
Key specs that matter in real life
- Ports: 1× USB‑C input/output, 1× USB‑C output, 1× USB‑A output.
- Total output: up to 140W max (USB PD 3.1 class power).
- Size/weight: 155.8 × 54.5 × 48.8 mm; 607 g.
Why this matters: 140W-class USB‑C means you can meaningfully charge many laptops (and do it quickly) instead of “maintaining battery percentage while working.”
The best part: the smart display
The on-device display isn’t a gimmick. It’s the difference between “I think I’m charging?” and “I know exactly what’s happening.” You can see input/output power and make quick decisions—swap a cable, change ports, or stop wasting time with a weak wall brick.
What to watch out for (the stuff that annoys people)
- It’s heavy. ~600 g is normal for this class, but you feel it in a sling bag.
- You need the right cable. To hit high wattage, use a 5A USB‑C cable (many cheap cables top out far lower).
- Airline rules vary. Large power banks can trigger airline scrutiny. Always check your carrier’s current battery policy.
Is it worth it in 2026?
If your week includes airports, coworking, classes, or long days away from outlets, yes—this is one of the few power banks that feels like it’s actually designed for modern USB‑C laptop life.
Amazon reality check: On Amazon US, the Anker 737 Power Bank listing shows 4.4/5 stars with roughly 16,482 reviews (snapshot taken today from the product page).
