Short answer — it depends on what you need. Below are the best power-bank picks (by use case) in 2025, why each is good, and the key buying rules you should know.

Top picks (by category)

• Best all‑round (phones + laptops): Anker 737 Power Bank (PowerCore 24K) — 24,000 mAh, up to 140 W total output (two USB‑C + USB‑A), smart display, fast recharge. Great if you want one pack that can reliably fast‑charge phones and high‑power USB‑C laptops. (anker.com)

• Best for multi‑device pros / high‑capacity laptop use: Zendure SuperTank Pro — ~26,800 mAh (≈96 Wh), up to 100 W per USB‑C and high total output, OLED display and firmware upgrades. Good if you frequently power a MacBook Pro or multiple devices for long periods. (powerbank.zendure.com)

• Best if you need an AC outlet: Mophie Powerstation Pro AC (or similar packs with an AC inverter) — large capacity (≈27,000 mAh) with a built‑in AC outlet for non‑USB gear; heavier but useful when you need to run small AC devices. (Reviews and roundup testing highlighted this class.) (engadget.com)

• Best compact / pocketable (daily carry): Anker Nano / PowerCore Slim (5,000–10,000 mAh options) — very small, light, and quick for one–two phone top‑ups; some models include a built‑in USB‑C connector or MagSafe style magnetic pad. Ideal for commuters. (anker.com)

• Best for iPhone users (magnetic): Anker MagGo / MagSafe power banks (10,000 mAh variants) — magnetic alignment, up to 15 W magnetic wireless (MagSafe) + USB‑C wired output. Convenient for cable‑free charging on iPhone 12+ series. (anker.com)

• Best budget / value laptop pack: Baseus Blade 100 W / similar 20,000 mAh 100 W banks — good balance of price, size, and laptop‑capable PD output if you don’t need 140 W. (Mentioned in recent laptop power‑bank roundups.) (engadget.com)

Important things to look for (quick buying checklist)

• Capacity (mAh vs Wh): mAh alone can be misleading. If you travel by air, check watt‑hours (Wh). Many ~25,000–27,000 mAh banks are right around 100 Wh — the usual airline cutoff. The FAA/TSA rules allow batteries up to 100 Wh in carry‑on without airline approval; 101–160 Wh may be allowed with airline approval; >160 Wh is generally prohibited. Always pack power banks in carry‑on, not checked baggage. (faa.gov)

• Output wattage and charging protocol: For fast charging laptops you want USB‑C Power Delivery (PD). New PD3.1 (28 V / up to 140 W) requires a PD3.1‑rated cable to reach advertised top speeds — otherwise you’ll be limited (common with 140 W bricks). Check device compatibility (some laptops don’t accept extremely high PD voltages). (anker.com)

• Ports and simultaneous output: If you’ll charge multiple devices at once, check total simultaneous output (not just per‑port). Some banks advertise very high per‑port numbers but limit combined wattage.

• Weight/size vs capacity: Higher capacity and higher output mean heavier bricks. A 20–27k mAh laptop bank typically weighs 400–900 g; pocketable 5–10k mAh banks are usually 100–250 g.

• Safety & airline compliance: Look for reputable brands with good safety features (cell management, overheat/overcurrent protection) and clear Wh labeling if you travel. Recent airline rule changes and several airlines restricting in‑flight use/placement of power banks make checking your carrier’s policy a good idea. (cnn.com)

Short recommendations by typical user

• Just need a daily top‑off for a phone/earbuds: 10,000 mAh slim bank (Anker PowerCore Slim or Anker Nano).
• Travel & multiple devices but want to stay TSA‑safe: 20,000–27,000 mAh, ≤100 Wh (e.g., Zendure SuperTank Pro ≈96 Wh / Anker 24k) — gives laptop and phone charges while being airline friendly.
• Need fastest laptop charging on the go: Anker 737 (140 W PD) if your laptop supports PD3.1 and you use a proper PD3.1 cable. If you need an AC outlet, get a larger “AC” power bank (Mophie or similar). (anker.com)
