I recently picked up the Nitecore NB Air Power Bank, and I’ve been impressed by how useful it is for something so small. It’s not a big or complicated piece of gear, but it makes life easier on camping trips, road trips with kids, and even day-to-day errands. This little power bank has quickly earned a spot in my backpack and my truck’s center console.
What It Is the Nitecore NB Air Power Bank
The NB Air is a pocket-sized power bank that delivers 5,000 mAh of battery power in a sleek, lightweight design. It weighs just 89 g (about 3.14 oz) and measures around 112 mm by 48 mm by 9.7 mm (roughly 4.4″ × 1.9″ × 0.4″).

It offers up to 18 W output via a single USB-C port (also used for input) and has a carbon-fiber reinforced build with an IPX7 waterproof rating—so it can even handle being submerged briefly.
- Capacity: 5,000mAh
- Input/Output: USB-C, up to 18W max
- IP Rating: IPX7 waterproof
- Price: $39.95
Compact and Pocket Friendly
The first thing that stood out to me is how tiny this power bank is. It’s slimmer than my phone and weighs almost nothing. I can slip it into any pocket, jacket, or backpack pouch and forget it’s there until I need it. The rounded edges make it comfortable to carry, and it never feels bulky.
Camping Use
When I’m camping, space is always tight. I don’t want to haul around heavy gear, and every ounce counts. The NB Air takes up no room at all but gives me the peace of mind of having backup power for small electronics. Whether it’s recharging my phone to check maps or topping off a headlamp, it’s nice to know I can keep the basics running without dragging along something bulky.

It’s also built tough, so I don’t worry about tossing it in my pack or using it outdoors. If the weather turns, I know it can handle a splash or two.
Car Trips With Kids
Long car rides with kids always mean charging battles. Phones, tablets, and handheld games all need power. Normally, that means cords running everywhere and kids fighting over who gets to plug in. The NB Air makes things easier. One kid can plug in, get a decent charge, and then the next gets a turn. Because it charges quickly, the system works and I don’t have to look at a mess of cords.
Everyday Use of the Nitecore NB Air Power Bank

Outside of camping or travel, I use the Nitecore NB Air Power Bank all the time because it’s so convenient. I slip it into my pocket when I’m out running errands, and I don’t have to worry about my phone dying. The battery indicator lights are easy to read, so I always know how much charge is left.
Since the NB Air doesn’t include a cable, I paired it with the Nitecore NLink10, a short, magnetic USB-C charging cable. It’s quick to attach, easy to stash in a pocket, and keeps me from carrying long cords around.

I also keep a pack of Nitecore NH2400 rechargeable AA batteries on hand. These power things like flashlights, lanterns, and even the kids’ toys on trips. They recharge via USB-C with the included cable, so I don’t need to carry a separate charger.

Nitecore NB Air Power Bank Highlights – What I Love
- NB Air is extremely lightweight and compact
- Durable enough for outdoor trips
- Charges phones and small devices quickly
- Reduces cord clutter in the car
- Truly pocket-sized and easy to carry anywhere
- NLink10 cable makes charging cleaner and easier
- NH2400 batteries save me from buying disposables

Considerations – What’s Missing
The NB Air has just one USB-C port, so I can only charge one device at a time, and there’s no pass-through charging. Since it doesn’t come with a cable, I recommend picking up the NLink10 or another short USB-C cable.
Final Thoughts
I enjoy using the Nitecore NB Air Power Bank because it’s simple, reliable, and easy to carry. It’s not the most powerful battery on the market, but it doesn’t need to be. For camping, car trips, or everyday use, it has proven itself useful time and again. Paired with the NLink10 cable and NH2400 batteries, I have a small, dependable charging setup that keeps my phone and gear ready without adding clutter.
