FAQS
What kind of power adapter should I use for charging?
You'll want at least a 5V, 2A adapter, but that's on the slow side. For a speedy charge, go for adapters rated at {9V, 2A); {12V,1.5A}; or {5V, 3A}. Quick and easy!
How can maintenance extend battery life？
A little battery drain when it's idle is totally normal! Just try not try to let it sit too long without charging, avoid overcharging it, andkeep it stored in a cool, dry place
to keep it in tip-top shape.
Is it okay to charge other devices with the battery while it’s connected to my heated jacket?
Not really a great idea! Charging multiple devices at the same timecan slow down the heating and compromise safety. After you're doone charging another
device, just long-press the power button to turn off the battery, theen restart it for the jacket.
How do I charge the battery?
No sweat! Just plug the USB end of the charging cable into a power acdapter that works, then pop the Type-Cend into the battery's side port. When you see the
"%" symbol flashing on the display, it's charging up! So just sit baack and let it power up

I've been extremely satisfied with this power bank, especially as a companion to my heated clothing. First, the compact size is a standout feature—it's card-sized, making it easy to carry, yet it packs a huge capacity. While it's not feather-light, it's still much lighter compared to similar high-capacity power banks, and for what it delivers, the weight is completely reasonable.
The LED display is a great addition, clearly showing the remaining battery life, and the contrast between the sleek black case and the bright display is visually appealing. I use it with the USB to USB-C cable, and it charges my devices faster than I expected. For example, it can charge my iPhone 12 Pro Max twice with some charge left over, and even while using my phone during charging, it brings the battery up to over 75% from under 10% within about an hour.
Beyond just charging phones, it powers my Wulcea heated clothing with no issues, delivering strong and reliable performance to keep the heating system running smoothly. I also appreciate that its capacity meets airline regulations, so it's convenient for travel, even though I haven't flown with it yet. Overall, this power bank is excellent, and I'm considering purchasing another one to ensure I always have one fully charged and ready to go. Highly recommended!
