Review: Tau 2 Keychain can avoid disasters in battery emergencies

I have first learned Rolling Square Square Square Square Square Square due to the upcoming Bluetooth tracking tracking, but I jumped at the opportunity to test Tau 2 first, the company’s small power bank. I never used one small and light, and they are two liking factors for light back riding inside me.

The timing was lucky. A few days ago, I forgot to run the plane while it is in the wild. I lost embarrassingly in the exurban area after darkness, my phone and a long dead digital map. My sense of direction (and a useful child from his mother’s car) eventually helped me find the train station and avoid a serious emergency, but I am lucky.

The ideal use of a small battery was described as “an emergency energy bank for each device”. Therefore, I used this review as an excuse to hit the forest again.

Price, availability and specifications

Rolling Square is a relatively suitable electronics company from Switzerland that does not contain many partnerships with large names. Currently, you can only buy Tau 2 directly from its location although this may change in the future.

It comes in ice gray and black mercury, including cables and a hat (with a major loop attachment) to frame the sides and up, and a little sports colors compared to the body. It costs $ 40, with discounts starting from $ 5 when buying two. Square ships are rolled to most countries around the world.

What is good in Rolling Square Tau 2 Power Bank?

He does everything he determines to do

The best part of Tau 2 is that I did not notice a pregnancy of 50 grams, about 6 by 4 by 2 cm ornament for one second. I installed it in a plastic bag to reduce potential rain, and I have speed it in my servants, and I often forgot this.

I say “mostly” because I throw it a little now for snacks. He never felt that he was remotely at risk of collapse, and there is another great advantage of the shape factor. The size, shape, and accurate construction gives it a very strong feeling. For this issue, I do not expect the IP classifying most of the energy banks, but I will not be afraid of a little rain while it is in my pocket. The device does not look like a little moisture that would harm it.

Of course, emergency equipment only helps if you already bear it. Tau 2 is barely compressed enough for comfortable use as a model key series. These features are also wide, with highlights and Micro-Usb sites along with expected USB-C. Tau 2 works well for suspended electronics in 2010 or from a specific system of Android competitor. The USB-C output does it faster than I expected.

It supports corridor charging, can charge two devices simultaneously, and accepts fees from a USB-C charger, or a mating shipping, a laptop or other battery for the device (using a simple touch sequence to choose the situation). The NFC brand associated with the Sherr.IT integrated into the back allows you to designate your contact information in the event of its loss, or you want your digital business card always ready. You can hang it from the embedded and tried magnetic pavement on the wall, keep your keys in one place and export your emergency battery.

All of these positives are concluded in a distinct package for sure. Its plastic body resists the scratches better than the key chain tools that I have tested before. Nothing feels cheap, and the cables offer a particularly strong building.

It seems that the manufacturer has thought about everything with Tau 2. Not only is the only option with an elegant shape factor, the square of the spacious feature of the feature of the wide features. Even after calculating my regards to all small and light things, I am unexpectedly pleased.

What is bad in Rolling Square Tau 2 Power Bank?

If you are difficult to please, you can complain, but just a little

The Tau 2 product tracker closely showed that it provides up to 1300 mAh for mobile devices, of its nominal capacity of 2000 mAh per hour. This number has been consistent with two iPhone devices, Android, and Android devices. This brought my daily drivers, the jelly star Uniherrtz Mineccule, to 60 % respectable, but most phones will only reach 20 % or so.

However, Tau 2 is not intended for additional hours of web browsing or watching videos. It is intended for emergency purposes, such as loss in the forest. However, I only contacted Rolling Square to make sure that the number 1300 mAh is not a defect. My contact confirmed that “the conversion is 100 % effective, which leads to a model capacity that can be used closer to 1700 mAh per hour. With standard differences in cargoing efficiency, it is normal to see about 1300 mAh per hour as an effective image, as some capacity is lost in this process.”

Physics and current battery technology limit this number. Only 50 grams, I cannot say that Tau 2 He should Electrons are more negative charging. It will be nice, but it will necessarily add weight.

Another thickness is thickness, which some people will find very hidden for the daily key series. I am not sure of the actual cell used, and I think Rolling Square made the device as thin as possible. In addition, I am difficult to satisfy with the pocket friendly tools (and from here my love for my generation star). If your daily horseback riding in a wallet, a boam bag or a similar accessory, you will not notice Tau 2. If you like the tight jeans as I do, your perfect key may not be completely.

My only potential complaint is how difficult it is to open the keys or a kind of attached cord. However, if you use it as an actual switch, this turns positively, so it is mostly washing.

Tao 2 competition

Other high -energy banks have positives and negatives. The global lamp lamp company Nitecore 5000 mAh earns the hour and 6000 mAh per hour at the same price, double weight, and slightly larger bodies. They do not offer compact cables or NFC mark. The Travelcard Plus Card costs the same capacity by 50 %, and it combines cables, but its likely credit card shape is not comfortable.

Aqua Vauult Chargecard is conclusively designed but it only carries 2300 mAh, almost almost a double cost. My Power Power Bank will be the next Vapcell P2150A, which is not more than 21,700 battery cells with a USB-C charging circuit at the top. If you agree to a little larger, Cuktech 10 is simplified just as a model of 10,000 mAh occurs. However, none of these shows has a distinct design, lightweight, and has an extended ingenuity in Rolling Square Square Square-Cheakke Power Bank.

Should you buy Rolling Square Tau 2 Power Bank?

If you want to be ready, yes

Although it is expensive given the capacity, the Tau 2 shape factor has no equal and a few competitors. It is a solid accessory, reliable, compressed that can save your life by running your phone in an emergency. It is not the absolute peak of diversity, but it deserves it for peace of mind.

In the end, a phone battery died shortly after waking up in the camp on the first day. Tao 2 did it. I stopped taking many pictures and remembered the activation of the plane. If we were in real danger (civilization was never far), it may have a disaster. And if I accidentally run the battery to zero at any time in the past few months, I recommend Tau 2. It is a stylish small device.
