If you are interested in charging devices like chargers or Power Bank, you must know the brand called Shargeek. And there’s a chance you might have heard of their famous STORM 2 power bank. Its unique look is really rare and is a very popular design style among geeks.

Now, we have got our hands on another version of the STORM2: the STORM2 Slim.

The STORM2 Slim box is really, really simple, with colorful lettering on a black background. Open the box. You can see there is no charging cable. The only accessories are a woven bag and a manual. So if you want to enjoy the fastest charging speed for a variety of devices, then you must bring your own high-spec charging cable.

Like STORM2, the biggest selling point of STORM2 Slim is definitely the design of the transparent shell. The transparent shell allows you to see the internal circuit boards and electronic components. I need to tell you that it is not a decoration, but a real working circuit board. The four purple columns are four 21700 lithium batteries, this type of battery and Tesla’s car battery is the same.

The advantage of this battery is the best balance between size and capacity. Geeks must love the design, and even non-geeks will think that the Power Bank is very high-tech. The small screen from STORM2 is of course retained in the Slim version. Next to the screen are buttons to operate it.

Why is the STORM2 Slim smaller than the STORM2? The answer lies in its front. You can see that it lacks a Type C port and a DC port, and the number of batteries is cut in half. This is the price of the smaller size. However, considering that most people do not use the DC port, reducing the size should be a change that the public would prefer. While the transparent shell is very nice to look at, it is also very easy to scratch. So you can see that Shargeek gave a woven bag, and the Power Bank wrapped tightly. It is to prevent you from accidentally scratching it. Anyway, this is the only one with such a cool cyberpunk style Power Bank, and I believe you will be hard-pressed to find a better-looking Power Bank.

Let’s talk about this little screen. It shows everything about the Power Bank. For example, charging power, voltage and current, remaining current, and even battery pack and circuit board temperature. Because it is equipped with the same Energy Storage Management OS as STORM2, you can make more detailed settings for its screen. This small screen is the equivalent of a Voltage Current Tester embedded in a Power Bank. This has the advantage that if you are like me, you are very concerned about whether the device is charging at maximum power. Then this Power Bank is just right for you. After all, if it’s not charging at maximum power, then there’s no point in me buying such a high-powered Power Bank.

Geeks won’t buy it if it just looks good but doesn’t work well. That’s why Shargeek has equipped the Power Bank with a 72Wh battery pack, which is equivalent to 20,000mAh. Because its capacity is below the maximum capacity limit that most airlines allow on board, you can take it on the plane without any problems. It has two charging ports with a maximum output of 130w at the same time, and a single port can also output up to 100w. The input power is also capable of reaching about 65w. Charging compatibility performance is also very good. The USB-A port supports all protocols except PD protocol, QC 4.0 and VOOC DASH protocol. And the USB-C port supports QC 5, PD 3.0 and PPS protocols. PDO has five fixed sets of levels covering 5 to 20 volts. The two port protocols add up to cover the full range of protocols. So don’t worry about your device not being able to fast charge, there is always a protocol that can Handshake with your device.

We tested the devices we have.

• Charging the Xiaomi 12 Pro supports up to 20w
• Mi 11 Ultra supports up to 28w
• Redmi K50 Gaming Edition up to 42w
• Redmi Note 10 Pro China version supports up to 15w
• iPhone 11 supports up to 8w
• OPPO Find X5 Pro up to 17w
• HUAWEI Mate 40 Pro up to 11w
• OPPO Pad supports up to 13w
• Lenovo Legion Y700 Gaming Tablet supports up to 15w
• Lenovo Xiaoxin Pad Pro 12.6 up to 16w
• The Nintendo Switch supports up to 8w at 90% power, and can activate TV mode.

So why would we buy such an expensive Power Bank.  If only for the high power or compatibility, there are many cheaper Power Banks on the market to choose from. The only reason you choose STORM2 Slim, is its beautiful appearance. As you can see from the name of the brand Shargeek, they wanted to make something that geeks would like. And they did.
