The Momax Airbox is a 10,000 milliamp-hour (mAh) power bank with three wireless charging spots, and in 2026 it remains a clever travel companion for Apple users, though newer magnetic power banks charge faster. It charges an iPhone, an Apple Watch, and AirPods at the same time, folds open like a clamshell, stores an Apple Pencil and AirPods inside, and adds a wired Universal Serial Bus Type-C (USB-C) port for a fourth device. This Momax Airbox review explains how it works, what independent testers found, where it falls short, whether you can still buy it, and which current alternatives on Amazon make sense.
Quick verdict: The Airbox is a clever travel companion for Apple users, especially because its built-in Apple Watch charger means you can leave Apple’s puck at home. Testers found slower recharging than Momax claims, the total output tops out at 20 watts (W), and its real-world capacity covers roughly one full iPhone charge plus top-ups for your watch and earbuds. Newer magnetic power banks charge faster, so buy the Airbox only at a good price. Check the Momax Airbox price on Amazon.
Key takeaways
- What it is: A foldable 10,000mAh power bank, introduced in late 2020, that wirelessly charges an iPhone, an Apple Watch, and AirPods at once and adds a 20W USB-C port.
- Who it’s for: Apple users who travel often, wear an Apple Watch, and want one case that charges and stores everything.
- Price: It sold for $107.99 with a discount code when Make Tech Easier reviewed it; as of November 2026, anything well below $100 counts as a fair deal. Prices change often.
- Main weaknesses: Total output caps at 20W, real-world capacity covers about one full iPhone charge, and the phone pad has no magnetic alignment.
- Successor: Momax’s Airbox Go (model MA02) keeps the 10,000mAh battery but adds magnetic charging at up to 15W for iPhones and raises total output to 25W.

Is the Momax Airbox still available?
Momax still lists the Airbox on its Hong Kong website, but US stock has thinned out over the years. You’ll mostly find it through third-party sellers on Amazon and eBay, and prices vary. When Make Tech Easier reviewed it, the Airbox sold for $107.99 with a discount code, so anything well below $100 today counts as a fair deal for a product of this age.
Momax’s follow-up, the Airbox Go (model MA02), keeps the 10,000mAh battery and the Apple Watch and AirPods charging but adds magnetic MagSafe-style charging at up to 15W for iPhones and raises total output to 25W. It listed for HK$1,520 (about $195) on Momax’s Hong Kong store. Other brands, including Anker, now sell magnetic Qi2 power banks that charge iPhones at 15W, which makes the original Airbox look dated if you mostly need phone power.
Design and build
Closed, the Airbox looks like a thick glasses case. Open it, and you’ll find the phone pad on one half and the Apple Watch and AirPods spots on the other. The compartments hold your AirPods and Apple Pencil in place, which helps keep a travel bag organized. Momax lists the Airbox in black, and it measures about 7.2 inches long and 1.3 inches thick.
Make Tech Easier found it too bulky for a pocket but fine for a purse, backpack, or carry-on. At 38Wh, it falls well under the 100Wh limit that the Transportation Security Administration (TSA) and most airlines set for batteries in carry-on bags. Remember that spare power banks must go in your carry-on, not your checked luggage.
Charging performance: what testers found
ChargerLAB measured about 19.4W from the USB-C port when charging an iPhone 13 Pro Max, which matches Momax’s 20W claim and fast-charges recent iPhones. The site also confirmed that the Airbox charges an iPhone, AirPods Pro, and Apple Watch wirelessly at the same time and supports pass-through charging, so you can recharge the Airbox while it powers your devices.
Wireless charging is slower. iPhones typically charge at up to 7.5W on standard Qi pads, and the Airbox’s watch and earbud spots run at 5W each. ChargerLAB also measured relatively low efficiency (about 64% at 15W), which explains why Momax rates usable capacity at 6,000mAh rather than 10,000mAh. In practice, expect about one full charge of a modern iPhone, plus some extra for your watch and AirPods, rather than the two full phone charges some listings suggest.
Recharging the Airbox itself took about 2 hours and 10 minutes at roughly 18W in ChargerLAB’s test, but Make Tech Easier reported a full recharge closer to six hours with its setup and found wireless recharging even slower. Use a 20W or faster USB-C Power Delivery wall charger for the quickest results. ChargerLAB also recorded surface temperatures above 60 degrees Celsius (140 degrees Fahrenheit) during a 20W stress test, so don’t leave it charging under a pillow or in a hot car.
Ease of use
Four lights show the remaining battery level in 25% steps, and three mode lights show whether fast charging (green) or 10W or 5W wireless charging (orange) is active. The Airbox shuts off automatically once your devices fill up. Make Tech Easier noted two annoyances: there’s no indicator light for the Apple Watch, and sometimes you can’t add a device while another one is charging without turning the Airbox off and on again. Like any Qi pad, the phone spot also needs your iPhone centered properly, and thick cases can slow or stop charging.
Momax lists Apple Watch support from the first generation through Series 6 and SE, so check compatibility if you own a newer watch. You can also charge an iPad or a MacBook Air over USB-C, but at 20W the Airbox only slowly tops up a laptop and will drain quickly doing it.

- Momax Airbox Go: The closest replacement, with magnets that snap your iPhone into place and higher total output. See the Momax Airbox Go on Amazon.
- Anker MagGo Power Bank (10K): It charges iPhones faster with magnetic Qi2, but you’ll need a separate charger for your Apple Watch.

Who should buy the Momax Airbox?
The Airbox suits Apple users who travel often, wear an Apple Watch, and want one case that charges and stores everything. Rideshare drivers and commuters can keep it in a bag for daily top-ups. Skip it if you mainly need to keep a phone alive, since a magnetic Qi2 power bank charges faster and weighs less, or if you own a newer Apple Watch that Momax doesn’t list.

Frequently asked questions
How many times can the Momax Airbox charge an iPhone?
The Momax Airbox can fully charge a recent iPhone about once. Momax rates the battery’s usable output at 6,000mAh, and wireless charging loses energy as heat, so wired USB-C charging gets you a little more.
Can I take the Momax Airbox on a plane?
Yes, you can take the Momax Airbox on a plane. Its 38Wh battery falls under the 100Wh carry-on limit. Pack it in your carry-on bag, since airlines don’t allow spare power banks in checked luggage.
Does the Momax Airbox charge the Apple Pencil?
No, the Momax Airbox doesn’t charge the Apple Pencil. It has a slot to store a second-generation Apple Pencil, but the Pencil charges on your iPad.
Can the Momax Airbox charge a MacBook?
The Momax Airbox can charge a MacBook, but only slowly. Its 20W USB-C port can top up a MacBook Air, but it can’t keep up with a laptop in heavy use, and it will drain the battery quickly.
Final verdict
The Momax Airbox remains one of the few power banks that charges an iPhone, Apple Watch, and AirPods together while storing them in one tidy case. Its 20W output cap, modest real-world capacity, slow recharging, and lack of magnetic alignment show its age next to newer Qi2 power banks and Momax’s own Airbox Go. Buy it at a discount if the all-in-one design fits your travel routine. Check the current Momax Airbox price on Amazon.
