Tau Power Bank Review
A tiny power bank that works with iOS and Android devices
If you're looking for a reliable and convenient power bank that you can carry with you everywhere, you might want to check out the Tau Power Bank. This is a keyring-sized power bank that can charge your phone or other devices with its integrated cables. It has three different connections: USB-C, micro USB, and Lightning, so it can work with any large iPhone or Android phone. In this substack post, I'll share my review of the Tau Power Bank and why I think it deserves 4/5 stars.
One of the pros of the Tau Power Bank is its design. It's small, light, and sleek, and it attaches to my keys easily. I don't have to worry about forgetting to bring a power bank or a cable when I go out, because I always have it with me. It also comes with a magnetic charging dock that I can stick to my wall or desk, so I can recharge it effortlessly whenever I get home.
Another pro of the Tau Power Bank is its performance. It has a 1,400mAh battery capacity, which may not sound like much, but it's enough to give me a 30% charge on my iPhone 14 pro or Samsung Fold 4. That's a lifesaver when I need some extra juice to make an important call, send an email, or use GPS. The charging speed is also decent, and it doesn't overheat or damage my phone.
A third pro of the Tau Power Bank is its versatility. It can charge not only my phone, but also my AirPods, my smartwatch, and any other device that uses USB-C, micro USB, or Lightning. It's like having three cables in one, and I don't have to worry about compatibility issues. It's also very handy for traveling because I can take it with me on the plane or in the hotel without any hassle. I especially like how they have combined the lightning and micro USB into one innovative connector.
However, the Tau Power Bank also has some cons that you should be aware of. One of them is its limited battery capacity. While it can give me a 30% charge on my phone, it can't fully recharge it or charge multiple devices at once. If you're a heavy phone user or need more power for longer periods of time, you might want to look for a bigger power bank.
Another con of the Tau Power Bank is its dependency on its dock. It only recharges via its magnetic dock, which means you can't use any other cable or charger to refill it. This can be inconvenient if you lose or forget your dock, or if you want to recharge it while you're away from home. Also, they provide hardware to screw the dock into a desk or wall, which damages the surface, it would be better if they provided a magnetic or some other non-destructive means to mount the dock on a wall or desk.
A final con of the Tau Power Bank is its size and weight. While it's small and light enough to fit on your keyring, it might also add some bulk and heft to your keys. If you already have a lot of keys or other items on your keychain, you might find it a bit cumbersome to carry around.
Overall, I think the Tau Power Bank is a great product that offers convenience, reliability, and functionality. It's perfect for anyone who needs a backup battery that they can always carry with them. It's also very affordable and well-made, and it comes with a one-year warranty. That's why I give it 4/5 stars and recommend it to anyone looking for a power bank.
