Why You Need a 2-in-1 Power Bank for Your Apple Watch and iPhone
Last week, I found myself in a crowded airport lounge, desperately hunting for two separate charging cables while my iPhone was at 12% and my Apple Watch had died somewhere over the Atlantic. I had my usual tangle of wires, a bulky power bank, and zero patience. It was that exact moment I realised my “travel charging system” was actually just organised chaos.
That’s when I started looking for something smarter. I didn’t want another brick in my bag; I wanted one compact gadget that could handle both my phone and my watch without me having to play plug-socket roulette. The NexTECH® Mini Capsule Power Bank with Wireless Watch Charger (£37.9) caught my eye because it promised to solve precisely this problem—and honestly, it’s been a game-changer for my daily routine ever since.
Design and Portability: The Capsule Form Factor
The first time I held this little thing, I actually laughed. It’s genuinely the size of a lipstick or a small capsule, which makes the “mini capsule power bank” name feel spot on. It slips into the tiny front pocket of my jeans, and I often forget it’s even there until I need it.
But the best part? The built-in wireless watch charger pops out neatly from the top, so I don’t have to carry a separate Apple Watch travel charger anymore. It’s a solid, premium-feeling device—not cheap plastic—and the digital display on the side shows me exactly how much juice I have left, which is far more useful than I expected. I’ve stopped guessing if my power bank is dead; I just glance at the screen.
Charging Speeds and Compatibility (iPhone & Apple Watch)
I was a bit sceptical about whether such a small device could actually deliver decent power, but I’ve been pleasantly surprised. When I’m at my desk and my iPhone is draining fast, I just pop the Capsule on the back (it works as a MagSafe power bank small enough to not feel bulky) and it starts juicing up wirelessly. It’s perfect for a quick boost before a meeting, not a full overnight charge.
For my Apple Watch, it’s even simpler—I snap the watch onto the integrated puck and it charges while I’m working or reading. It’s fully compatible with my Series 8, and I’ve also tested it with a friend’s Ultra; no issues at all. The charging speeds aren’t lightning-fast, but they’re completely reasonable for a device this size, and the convenience far outweighs any need for speed.
How It Compares to Other Mini Power Banks in 2025
I’ve tried a few other portable charger with watch charger options over the years, and most of them are either too heavy or require you to carry separate cables. Some “2-in-1” gadgets I’ve tested have a flimsy pop-out watch charger that feels like it will snap off after a week. The NexTECH capsule feels robust, and the magnetic alignment is strong—my watch clicks on with a satisfying snap.
Compared to other mini power banks on the market, this one wins on pure form factor. Many competitors are small but don’t have the integrated watch charger, meaning I’d still need a cable. Others have the watch charger but are twice the size. At £37.9, it’s also reasonably priced—I’ve seen less capable products for more money. This is the first one that truly feels like a complete solution rather than a compromise.
Real-World Use Cases: Travel, Gym, and Daily Commute
On my last weekend trip, I ditched my usual charging pouch entirely. I just threw the Capsule into my dopp kit, and that was it. At the airport, I charged my AirPods and iPhone without ever finding a wall outlet. In the hotel, I used it to top up my watch overnight while the phone charged from the mains. It genuinely replaced three separate chargers.
I’ve also started taking it to the gym. I used to dread my watch dying mid-workout, but now I just clip the Capsule to my gym bag and give my watch a quick boost between sets. And on my daily commute, when my phone drops below 20% by 5pm, I just attach the Capsule to the back for a wireless top-up on the train. It’s become one of those things I don’t leave home without.
Who Should Buy the NexTECH Mini Capsule Power Bank?
If you’re someone who carries an iPhone and an Apple Watch and hates the idea of carrying a separate charger for each, this is for you. It’s perfect for frequent travellers, gym-goers, and anyone who’s tired of cable chaos. If you primarily use a non-MagSafe Android phone, you might still benefit from the watch charger and USB-C output, but you won’t get the same magnetic convenience.
However, if you need to fully charge your iPhone from zero to 100% multiple times a day, this isn’t that—it’s a top-up device, not a power station. But for 90% of my daily life, it’s more than enough. I’d recommend it to anyone who values minimalism and practicality over raw capacity.
Final Verdict: Is It Worth It?
Honestly, yes. After two weeks of using the NexTECH® Mini Capsule Power Bank, I can’t imagine going back to my old setup. It’s solved a problem I didn’t even realise was annoying me until it was gone. The fact that it charges both my iPhone and Apple Watch in such a tiny package feels like magic, and the £37.9 price tag feels like a steal for the convenience it brings.
If you’re on the fence, just think about the last time you were stuck with a dead watch or phone and no cable in sight. This little capsule would have saved you. I’ve already ordered a second one for my partner, and I’m seriously considering one for my desk and one for my travel bag. It’s rare that a gadget lives up to its hype, but this one genuinely does.
