This is my review of the TAU Power Bank: It boasts a unique and compact design with handy keychain compatibility. I purchased it for $25. Hope this review is helpful for those considering buying. Feel free to ask any questions in the comments section.
General Information about the TAU Power Bank: Unique and compact design with convenient keychain compatibility
Power banks are the most common tech accessories nowadays, serving as a lifesaver for travelers. However, the TAU power bank, despite its unique, compact, and convenient design, falls short with a mere 1,400mAh battery capacity. Yes, you heard it right, a power bank with only 1,400mAh capacity!
Technical Specifications:
Input/Output Power: 5V - 1A (5W)
Battery capacity: 1,400mAh
Charger dimensions: 60x45x12mm - 40g




Things I Like
TAU has a compact and convenient size, allowing you to carry it in your pocket without taking up extra space in your backpack.
The TAU power bank features a Hybrid charging cable design with 2 cables integrated into its body - 1 type-C port and 1 Lightning port. I find this design to be clever and convenient as it eliminates the need to carry tangled charging cables around.
Moreover, there's an aluminum piece on top of the charger, serving as a convenient hook for hanging. You can hang it on your belt loop or keychain, giving it a stylish look.
The magnetic charger design with the wall-mountable charging dock is quite cool and intriguing.
Use fire-resistant materials during emergencies.




Aspects I Dislike
The low battery capacity of only 1,400mAh, lack of fast charging support, not suitable for replacing other power banks. When charging my iPhone 12 Pro Max, the charger goes from 12% to 30% and runs out of battery. With such low battery capacity, it might be more suitable to use TAU as a backup charger for wireless earbuds that occasionally run out of battery.You can refer to the charging table of various devices via the TAU power bank in the image below
Should You Buy It?
I don't think this is a very useful power bank for us. The low battery capacity is a big downside for power bank devices. However, due to its compact size, you can carry it with you everywhere and only use it when necessary. However, if you're someone who loves tech products like me and enjoys something unique and innovative, I think TAU is worth buying. That's just my opinion, what do you guys think?
