The best power bank for iPhone 18 Pro and Pro Max is the BMX SolidSafe Air 10K ($79.99). It gives the phone its full 25W wireless speed, holds 10,000mAh, and does it in a 13mm titanium body slim enough that you actually carry it.
You bought a phone that takes 25W wireless. Most of the 10,000mAh magnetic packs in this guide are 18 to 21mm thick, and a pack that thick ends up in a drawer. A power bank in a drawer charges nothing.
Three tests decide the best iPhone 18 Pro power bank
Three tests, in this order. A pack that fails the first one can't win.
- It has to charge at 25W. The iPhone 18 Pro and Pro Max take up to 25W over MagSafe and Qi2. An iPhone 15 Pro took 15W. A 15W pack still snaps onto an 18 Pro and charges, at 15W: whichever is slower sets the speed, and on an 18 Pro the slow one is the pack. On the box, look for Qi2.2 or Qi2 25W; a pack that just says Qi2 or MagSafe-compatible may top out at 15W.
- It has to fit the phone. The 18 Pro is 71.9mm wide and the Pro Max is 78.0mm. A pack wider than the phone hangs off the sides, which you feel every time you pick it up.
- It has to be thin enough to carry. 10,000mAh is about two phone charges, the right amount for a Pro used hard. Thickness and weight decide whether those charges are with you at 4 p.m.

Why the Air 10K wins on an iPhone 18 Pro
The Air 10K fits 10,000mAh into 13mm, about the thickness of a Sharpie, at 191.3g. It is 69.6mm wide, so it sits inside the 18 Pro's 71.9mm edges and leaves about 4mm of phone showing on each side of a Pro Max.
Why titanium? It keeps a case that thin light and tough, and it helps spread heat, which matters for something pressed against a charging phone for an hour.
Why semi-solid-state? Liquid electrolyte is the flammable part of a conventional lithium-ion cell. SolidSafe cells use significantly less of it, which helps reduce fire risk in a pack that lives on your phone all day.

The other BMX packs do different jobs
Want a screen that shows live watts and a USB-C cable built into the pack? The SolidSafe 10K ($79.99) does that at 15W magnetic. Want the lightest thing that snaps on? The SolidSafe Air 5K ($59.99) is 6.8mm of titanium and 5,000mAh at 15W. For the full 25W, it's the Air 10K.
The wall charger is the other thing the box leaves out
Open the box and you get the phone and a 1-meter USB-C cable. No adapter. Apple's fastest wired result, up to 50 percent in around 15 minutes, is written around a 60W-capable adapter with Adjustable Voltage Supply. Our iPhone 18 Pro charger guide explains what that means for the charger you already own.
Want both in one order? The pair below adds the BMX GaNSta 70W wall charger.
What people ask about iPhone 18 Pro power banks
Will my MagSafe power bank from my last iPhone work on the 18 Pro?
Yes. It snaps on and charges, at whatever rate it was built for. A 15W pack stays a 15W pack; the 18 Pro's 25W only shows up with a 25W pack.
Is 5,000mAh enough for iPhone 18 Pro Max?
For one top-up, yes. Apple hasn't published the Pro Max battery in mAh, so treat 5,000mAh as about one charge and 10,000mAh as about two. If you run the Pro Max hard all day, get the 10,000mAh.
Can I take the Air 10K on a plane?
Yes, in your carry-on. It is 38.5Wh, under the 100Wh carry-on limit. Keep it out of checked bags.
What if it does not fit my case, or I change my mind?
