Pros
Outdoor use with power bank (approx. 96 users, 70%). No need for 220V power, so you can use it anywhere - camping, car camping, picnics, and more. One reviewer said, "It's essential for camping. With just a power bank, I can sleep warm in my tent."
Fast heating speed (approx. 76 users, 55%). The graphene carbon heating element warms up quickly after power connection. One reviewer said, "It amazed me how warm it got in just 1-2 minutes."
Portability (approx. 69 users, 50%). The included dedicated pouch makes storage and carrying convenient. One reviewer said, "It folds up small enough to fit in a carry-on."
Machine washable (approx. 55 users, 40%). Can be washed in a laundry bag after removing the cable for hygiene. One reviewer said, "It still heats well after washing."
Soft microfiber material (approx. 48 users, 35%). The 3mm thick microfiber fabric feels soft to the touch. One reviewer said, "The texture is really soft, feels nice even against bare skin."
Cons
Heating area concentrated in center only (approx. 28 users, 20%). Only the center area (6x75cm x 2 lines) heats up, not the entire blanket. Solution: Maximize heating effect by placing the back side (controller side) against your body and sitting or lying on it.
1-hour auto-off (approx. 21 users, 15%). While a safety feature, it can be inconvenient for extended use. Solution: Use regular electric blankets for sleeping, and use this product for short breaks or while moving.
Power bank capacity limitations (approx. 17 users, 12%). Requires a 30,000mAh+ power bank, and older batteries may have insufficient output. Solution: Use a newer power bank with confirmed 5V 2A output.
Cannot use C to C cable (approx. 14 users, 10%). C to C cables won't work due to 5V 3A overcurrent issues. Solution: Always use the included USB to C type cable or one with identical specs (5V 2A).

Opinions were divided on heating performance. One reviewer said, “It’s really warm when I lay on it with the controller side down.

Frequently Asked Questions (FAQ)
How much does the Vitagram USB Graphene Blanket cost?
Currently available on Coupang for ₩27,040 KRW. Next-day arrival available with Rocket Delivery orders, including the blanket, USB C-Type cable, dedicated pouch, and user manual.
Where can I buy it at the lowest price?
Coupang Rocket Delivery offers the best price and fastest shipping. ₩27,040 KRW includes all components and is competitively priced compared to other sellers.
What power bank capacity do I need?
A 30,000mAh or higher power bank is recommended. It must support 5V 2A output. Power banks used for 2-3 years may have reduced output, causing weak heating. Test with a new power bank or 220V phone charger (5V 2A).
Can I use a USB C to C cable?
No, it won’t work. C to C cables are 5V 3A spec, causing overcurrent and preventing the product from working. You must use the included USB to C type (5V 2A) cable or one with identical specs.
Why does the heating feel weak?
Use it with the back side (where the controller is) facing your body, either sitting or lying on it. This product performs best when laid under you rather than draped over, minimizing heat loss. Also, wear thin clothes rather than thick ones and use it in close contact for better warmth.
Is it washable?
Yes, it’s machine washable. After removing the cable, hand wash below 30C or put it in a laundry bag for machine washing. Do not use dryer, iron, or bleach, and boiling or soaking is not allowed.
Why does it turn off automatically during use?
The 1-hour auto-off safety feature is activated. It may also turn off due to poor USB cable connection or insufficient power bank output. Ensure cable is properly connected and try a new 30,000mAh+ power bank.
Does the entire blanket heat up?
No, there are two 6x75cm heating lines in the center only. Keep this in mind and position your body close to the heating area for effective use.
What occasions is it good for?
Great for camping, car camping, vehicles without heated seats, offices, classrooms, and travel. Especially useful with a power bank when outdoor activities don’t have 220V power, suitable for short breaks or warmth while moving.
How many temperature levels are there?
3 temperature levels: Level 1 at 35C (green LED, spring/fall), Level 2 at 45C (blue LED, chilly autumn), Level 3 at 55C (red LED, cold winter). Each temperature may vary by +-5C.
