INIU SnapGo Air review: fast charging in a compact magnetic pack
INIU SnapGo Air fits snugly on the back of MagSafe-compatible devices

The INIU SnapGo Air Magnetic Power Bank 10000mAh (P781) holds close to its full rated capacity, recharges quickly, and stays cool even after sustained heavy use – results strong enough to earn it Techlicious Certified status in our portable battery charger testing. A magnetic Qi2 panel on the back lets it snap onto a MagSafe-compatible phone and charge wirelessly, while a pair of USB-C ports handle wired charging at up to 45 watts.
Design and portability
The power bank ships with an integrated braided cable that tucks into a small protective cap when not in use, so there's no separate cord to track down or lose. That cable forms a loop at the end, letting you thread it through a backpack strap or belt loop the way you'd use a carabiner.
The braided USB-C cable is conveniently stored on the SnapGo Air and doubles as a clip or handle.

Packaging is minimal cardboard, and the bank comes out of the box without needing scissors or a knife to cut through seals or plastic.
At 7.1 ounces and roughly the footprint of a deck of cards (though much thinner at only 0.5 inches), it's built to disappear into a purse or pocket, and its capacity to weight ratio of about 5.6 watt-hours per ounce puts it well ahead of most banks in its class. INIU sells it in six colors, including the space gray we tested, along with midnight navy, sunset orange, soft lilac, metallic mocha, and lunar silver.
Charging performance
In testing, the power bank converted about 30 to 32 watt-hours of its 39.2 watt-hour internal battery into usable charge for a connected phone. That approximately 80% efficiency rating is at the top of our expectations for a bank this size. Recharging from empty took about 1 hour 48 minutes on average, among the fastest we've measured in this capacity class. Surface temperature never exceeded 95 degrees Fahrenheit during testing, staying comfortable to hold even under load.
Dual USB-C ports charge two devices at once, or recharge the power bank while charging another device.

Output from each of the two USB-C ports held near the rated 45 watts through most of a charging cycle, though it throttled down to 24 watts after 20 minutes of sustained heavy use in one test run as internal temperatures climbed. Running both ports at once dropped combined output by more than 80 percent from the single port rate, which sounds steep but is typical for power banks this size, where splitting full output evenly across two ports isn't a realistic expectation.
Special features and durability
The SnapGo Air supports full speed pass through charging alongside its 25 watt Qi2 wireless charging, so it can charge a connected device while itself being recharged without a speed penalty. A status button on the front lights up a display showing remaining battery life as a clear percentage, though it doesn't show charging wattage or which protocol is active, information some testers would have liked to see.
INIU backs the bank with a 30 day refund window and a three year limited warranty covering manufacturing defects, plus lifetime technical support, though the company doesn't publish a cycle count rating for the internal battery.
How we tested
Techlicious evaluated the SnapGo Air using a ChargerLAB POWER-Z KM003C power analyzer for USB-C output readings, with an FNIRSI FNB58 as a secondary meter to cross-check wattage, and an infrared thermometer to track surface temperature during sustained discharge.
Two testers ran independent passes: charging test phones from the bank, timing a full recharge from the wall, logging output with both USB-C ports active at once, and measuring weight and dimensions for the portability figures. Their results were averaged to produce the numbers reported here.
Testing followed Techlicious Certified's Portable Battery Charger standard, which also requires UL 2056 or CE plus EN 62133 safety certification.
Bottom line
At $54.99, the SnapGo Air provides everything that matters for day to day use (capacity, recharge time, thermal safety, portability), performing at or above what the price suggests it should.
