3 things you'll notice the first time you use the POCKET 5.
IT JUST SNAPS ON AND WORKS - Pull the integrated cable out of its storage slot, snap the power bank magnetically to the back of your phone, and plug in. That's it. One hand, one motion, and you're charging while you keep walking, texting, or navigating.
YOU ACTUALLY FORGET IT'S THERE - This sits flush against your phone like a slim case rather than a bulky battery pack. The metal body dissipates heat efficiently, so it stays comfortable even during fast charging output.
YOUR PHONE CHARGES FAST - Wired USB-C delivery means you're getting meaningful charge quickly. Plug your phone in at 15% before heading into a meeting, and you'll have a usable charge by the time you walk out.
TWO DEVICES, ONE POWER BANK - The USB-C port and the integrated cable both deliver fast charging individually. Plug a friend's phone into the port while yours charges from the cable.
PASS-THROUGH KEEPS EVERYTHING TOPPED UP - Plug the POCKET 5 into a wall adapter and it recharges itself while continuing to charge your connected device. Great for overnight on a nightstand or at a café when you only have one outlet.
IT HANDLES RAIN AND SPLASHES - Waterproof rated, so getting caught in a downpour or setting it down near a wet sink isn't an issue. Multiple layers of protection cover both internal components and external seams.
WHY THE POCKET 5 STANDS OUT
Higher Energy Density
The 3.87V high-voltage cell delivers 154.8mWh/g energy density and 3,400mAh rated energy at 5V - approximately 21% more usable power than the 2,800mAh average from standard 5,000mAh magnetic power banks.
V0 Flame-Retardant + 9 Protection Systems
Housing rated V0 (the highest UL 94 flammability class), backed by an MCU and dual NTC thermistors managing overcurrent, thermal, short-circuit, overvoltage, and five additional protection layers.
Wired Charging, Magnetic Attachment
Most magnetic power banks rely on wireless charging, which loses significant energy as heat. The POCKET 5 delivers wired USB-C speed with magnetic convenience - faster charging, cooler operation, more energy reaching your phone.
UN38.3 Flight Certified
Tested and certified to UN38.3 transport safety standards. At 19.35Wh, the POCKET 5 is well under the 100Wh carry-on limit for commercial flights - one less thing to worry about at airport security.
102mm x 70mm x 9mm. Smaller than a deck of cards, thinner than most phone cases.
The POCKET 5 slides into a front jeans pocket and disappears. At 9mm (0.35") thick, it adds barely any bulk when magnetically attached to your phone - close to the profile of a slim case rather than an external battery.
The aluminum alloy housing serves double duty: it gives the POCKET 5 a premium bare-metal feel while actively pulling heat away from the battery cell during charging. The surface stays comfortable to hold against your phone or in your hand, even under sustained fast-charge output.
Dimensions: 102mm x 70mm x 9mm (4.02" x 2.76" x 0.35"). Weight: 125g ± 5g (4.41 oz ± 0.1 oz).
Two USB-C outputs. 22.5W each. PD, QC3.0, and SCP support.
Both the built-in USB-C cable (C2) and the USB-C port (C1) support 22.5W max output individually, with PD, QC3.0, and SCP fast charge protocols. Connect one device to each for simultaneous charging at up to 15W total output.
The 3.87V high-voltage cell packs 154.8mWh/g energy density - about 21% more rated energy than standard 5,000mAh magnetic power banks running at typical 3.7V. That means more of the stored energy actually reaches your phone rather than being lost to voltage conversion.
Input runs at 18W max through either USB-C connection point, so you can recharge the POCKET 5 itself using the built-in cable plugged into a wall adapter, or through the USB-C port with any standard cable.
Pass-through charging lets you recharge the POCKET 5 and power your device at the same time - useful when you're at a desk with one available outlet and two devices that need power.
Magnetic grip exceeding 10N - strong enough to hold approximately 5 smartphones.
The POCKET 5 snaps to the back of your phone instantly and stays locked in place. In Nitecore Lab testing using an iPhone 17 (177g / 6.24 oz) as reference, the magnetic grip held approximately 1,000g (35.27 oz) - roughly equivalent to 5.6 iPhones stacked together.
The magnetic attachment requires zero alignment. Bring the POCKET 5 near the back of your phone and it snaps into the right position on its own, making one-handed attachment effortless.
iPhone users: Works directly with any MagSafe-compatible iPhone, or with a MagSafe case. No adapter needed.
Android users: Requires a magnetic case for attachment. A magnetic ring is included in the box for phones and cases that need it.
Note: "Magnetic" refers to physical attachment only. The POCKET 5 does not support wireless charging - all power delivery is through wired USB-C, which is faster and more efficient.
IPX7 waterproof, V0 flame-retardant, built for daily reality.
The POCKET 5 handles the kind of conditions that would kill most power banks. IPX7 waterproof rating means heavy rain, accidental puddle drops, and damp backpack pockets are all handled. Multiple layers of waterproof protection cover both the internal components and external seams.
The housing uses V0 flame-retardant material - the highest UL 94 rating for resistance to ignition. Combined with the multi-layer waterproof sealing, this power bank is built to take everyday bumps, moisture, and temperature variation in stride.
Note: The POCKET 5 is not designed for underwater use. Dry thoroughly before use if it's been submerged accidentally.
MCU + dual NTC thermistors with 9 built-in protection systems.
A dedicated microcontroller unit monitors the POCKET 5's charging and discharging in real time, paired with dual NTC thermistors for precise temperature sensing. Together, they manage nine layers of protection:
Overcurrent protection, intelligent thermal protection, optimized charge/discharge efficiency, short-circuit protection, over-discharge protection, button protection, overcharge protection, accurate power indication, and overvoltage protection.
The 4-LED power indicator system gives you a clear read on remaining capacity: all 4 lit means 75-100%, down to 1 flashing LED when you're below 10% and it's time to recharge.
Operating temperature range: -10°C to 35°C (14°F to 95°F). UN38.3 certified for safe air travel - you can pack the POCKET 5 in your carry-on bag with confidence.

Does the POCKET 5 support wireless charging?
The POCKET 5 does not support wireless charging. "Magnetic" refers to the physical snap-on attachment only. All charging is delivered through wired USB-C - which is significantly faster and more efficient than wireless alternatives.
Can I bring the POCKET 5 on a plane?
Yes. The POCKET 5 is UN38.3 certified and its 19.35Wh capacity is well under the 100Wh limit for carry-on lithium batteries on commercial flights. Pack it in your carry-on bag (not checked luggage, per airline regulations for lithium batteries).
Will it work with my Android phone?
Yes, with a magnetic case. iPhones with MagSafe work directly (with or without a MagSafe case). For Android phones, you'll need a magnetic case - or you can attach the included magnetic ring to your existing case to enable snap-on attachment.
Can I charge the POCKET 5 through the built-in cable?
Yes. You can recharge the POCKET 5 by connecting the built-in USB-C cable to any USB-C power adapter, or by connecting a separate cable to the USB-C port. Both inputs accept up to 18W.
How do I check the remaining battery level?
Short press the Power Button. The 4 LED indicators light up to show the remaining charge: 4 LEDs = 75-100%, 3 LEDs = 50-75%, 2 LEDs = 25-50%, 1 LED = 10-25%, 1 flashing LED = below 10%. During charging, all 4 LEDs stay solid when fully charged.
