A practically perfect portable power pack：iWALK T08C 8000

This power bank is sleek, it's black, and it looks like a mechanized scorpion that was designed deep within the bowels of a research facility at some far-eastern military complex from the not-too-distant future using advanced technology acquired from an ancient alien vessel which carried transforming robotic beings that crash-landed on Earth 4 million years ago.
For me, the most important aspect of the iWALK T08C Power Bank (and I cannot stress this enough) is that you do not need to carry any additional cables with you. It already has all of the cables, and they don't come off. I hate, hate, hate the fact that almost every other portable battery solution, with a few notable exceptions, require you to carry one or more cables with you to charge your devices. Sure, the integrated cables are only like 5 inches long (that's 12.7 cm) but it's much better than having no cables at all. I have had other similar devices from other companies (even some with the fantastic integrated-cable design) but this one has USB-C, and it's the first one I have seen that also has an integrated cable to charge itself. It's brilliant, and I will explain the connectivity options in detail.

This particular configuration offers two integrated, non-removable cables along the sides for power output: Micro USB, and the future of computing interoperability: USB Type C. There is also a single female USB Type A port for power output; this is the same rectangular USB port you would find on every computer for the last 20 years. You can plug in a USB cable to charge a device if you want to use a longer cable than the ones integrated into the power bank. It also means you can theoretically charge up to three devices simultaneously. As for power input to charge the power bank, there are two options: first, there is a female Micro USB port, which necessitates a separate cable such as one that might charge your phone. The second option is a short, flat integrated cable that runs along the bottom of the device, and ends in a male USB Type A connector. This means you can plug it in to any USB power source to charge the power bank without needing to bring with you any cables whatsoever. All three of the integrated cables tuck into the sides and bottom of the power bank when not in use. They are easy to access, and easy to put back into place.

Make no mistake, USB-C is the future, and will be the standard for the next 30 years. Of course, the cells in this power bank will not last 30 years, but for what life they do have, this device will remain quite future-proof. Those of you with Apple devices will have to look for a configuration with a Lightning connector... at least until your masters in Cupertino see fit in their all-knowing benevolence to provide you a non-proprietary connectivity option. (There are rumors that the 2017 iPhone will sport USB-C, as do the current MacBooks.) Alas, between Micro USB and USB-C, I can charge every portable device I own, including the Google Pixel and the elusive Nintendo Switch. Yes, it will charge the Nintendo Switch; I tried it, myself.
The design aesthetic of the power bank is simple, and fairly minimalistic.It also White sell online. The body is a hard, quality plastic. The bottom is flat and smooth, and the top has an nice-looking pattern that looks like it would provide great traction if you could walk on it; it certainly helps with grip. There are LEDs on the top, near the front, that indicate the remaining power within the cells. They activate when you press a small button on the front of the device. This is also how you would turn it on to tell it to begin sending power to your connected devices. There is no flashlight on this thing, as is available on some other USB batteries, but I have had a couple such devices, and never used the flashlights on them only once or twice.

It has good aesthetics, good color options, create connectivity options, and an innovative solution for integrating all of the cables that you will need. At 8000 mAh, it will charge most phones several times. Other products, including some by the same manufacturer, have more power, but they are also larger, and none so far offer all of the complete cable integration that I can't stop talking about in this review. I do wish that it had a USB-C input for power, but USB-C is not yet common enough for that to be very practical right now. Also, It does NOT rapid-charge the Google Pixel or the Nexus 6P via USB-C. It does support Qualcomm Quick Charge (which, despite their similar-sounding names, are different technologies.)
In summary, this design is as close to power pack perfection as I have ever seen. I bought it, I would buy it again, and If IWALK Global make a larger, higher capacity version with a similar design, I will buy that as well.
