Portable multi-device chargers are a must-have for frequent travelers. They keep your iPhone, Apple Watch, AirPods, and even other devices powered up when you’re away from home. Alogic’s newly launched Roam 21,000mAh 6-in-1 Power Bank takes things a step further by combining all these charging needs into one sleek unit, helping you stay charged even without a fixed power source.
I’ve been testing the Roam for a few weeks now, including during a week-long, multi-stop trip across the U.S., and I’ve found it to be a handy travel companion—though it does come with a few trade-offs.
A Power Bank with Serious Versatility
Consisting of a 77Wh (21,000mAh) powerhouse, the Roam provides several charging surfaces, ports, plus a built-in USB-C cable. All of this helps keep nearly any device you’re carrying charged up while on the move.
While it folds into a relatively compact rectangular form, once opened for use, the Qi2 magnetic phone charging pad and the Apple Watch charger swing up into position. There’s also a recessed Qi charging surface for your AirPods. For charging devices like an iPad or Mac, there’s a short built-in USB-C cable on the side, plus two additional USB-C ports on the back.
Design and Build
The body is made of matte black plastic with an aluminum strip around the edges, which gives it a premium look—but it does tend to pick up fingerprints over time.
The phone charger is a MagSafe-compatible Qi2 charger that supports up to 15W of power for most newer iPhones. It’s not quite as fast as the 25W MagSafe charging found on the iPhone 16 series, but it gets the job done. In my testing, it was able to charge the iPhone 16 Pro Max to 50% in under an hour, which is on par with other Qi2 chargers.
The folding pad can be set at various angles—from flat against the power bank to nearly 90 degrees—making it easy to charge your phone in either portrait or landscape mode using StandBy.
AirPods and Apple Watch Charging
Lifting the Qi2 pad reveals a simple 5W Qi pad for your AirPods. It doesn’t have magnetic alignment, but it charges wireless-capable AirPods cases just fine.
The Apple Watch charger flips out from the back and matches the matte black finish of the Roam—a nice change from the usual white puck. The design supports Nightstand Mode, though its placement behind the Qi2 charger means you may not be able to view the watch while it’s charging. That said, the iPhone’s StandBy display is generally more useful at night.
One major downside to that: the Apple Watch charger isn’t necessarily fast. It merely charges at 2W of power, or in my case, after testing it for an hour, I found that the Apple Watch Ultra 2 only charged by 25%. A fast charger would’ve delivered around 80% in the same time. So if you’re someone who likes to charge your watch quickly before bed (rather than overnight), this could be a limitation.
USB-C Charging Power
The Roam includes a built-in ~5-inch USB-C cable that supports up to 100W of power delivery, along with two USB-C ports on the back—one supports up to 100W and the other up to 18W. Just note that the Roam can only output a combined maximum of 100W, so if you’re using multiple ports, that power is shared.
For input charging, the Roam supports up to 65W either through the built-in cable or one of the USB-C ports. Charging from 25% to 90% took about 90 minutes, with the remaining charge taking a bit longer—reaching 97% after 2 hours. If you’re using the 100W USB-C port to charge the Roam, pass-through charging is supported (so you can charge other devices while charging the power bank), but this doesn’t work if you’re using the built-in cable.
Battery Monitoring and Controls
To help monitor battery status, the Roam includes a small LCD on the side showing the current battery level, plus some green icons that display charging input/output information. There’s a power button on the back to turn the device on or off, and to activate pass-through charging. The Roam also automatically powers down after some idle time to save battery.
Travel-Ready but a Bit Heavy
The 21,000mAh battery (77Wh) is within airline limits, so it’s safe to bring on flights. However, it does have some heft. The Roam weighs 606 grams (around 1.3 pounds). It’s not too much to carry in a bag, backpack, or carry-on, but you’ll definitely notice the weight if you’re traveling light.
Its dimensions are 158mm x 82mm x 35mm (roughly 6.2″ x 3.2″ x 1.4″), so it’s about the size of a Pro Max iPhone but significantly thicker and almost three times as heavy.
That size and weight are the price you pay for carrying a good chunk of battery power with you—but how much do you really get from 21,000mAh? Alogic claims it can charge the iPhone 16 up to four times, and my real-world use with the iPhone 16 Pro Max aligns with about three full charges. The iPhone 16 Pro Max has a 4,685mAh battery, so theoretically, it could get four charges, but due to energy transfer inefficiencies, three is a more realistic number.
AirPods and the Apple Watch don’t draw much power, but if you start charging larger devices like an iPad or MacBook, the battery will drain much faster. You could fully charge a 13-inch MacBook Air once, but not a 15-inch model, and certainly not a MacBook Pro—especially if you’re also charging your iPhone and other devices.
The Bottom Line
The Roam 6-in-1 Power Bank is ideal for weekend trips off the grid, where you only need to charge smaller devices a few times. It’s not powerful enough to keep a full lineup of Apple gear (iPhone, iPad, MacBook, Apple Watch, AirPods) going for multiple days, but that’s more of a limitation of battery tech than the device itself.
Its biggest strengths—convenience and all-in-one design—do come with added size, weight, and cost. If you’re looking for a simple, barebones power bank in the same capacity range, you can find cheaper and lighter options. But you’d need separate cables for each device, and you likely wouldn’t be able to charge as many things at once.
Alogic Roam is a premium product, built for travelers who value simplicity and are willing to pay (and carry a bit more) for that convenience. The Roam 21,000mAh 6-in-1 Power Bank is available on Alogic’s website, normally priced at $197.99, but currently on Easter sale for $158.39 (20% off).
