With the rapid development of digital products, the shortcomings of digital products are revealed - the battery is not durable. Smart phones need to be charged every day, and fancy smart watches need to be charged every day. It's really no good to go out without a power bank, and various strange power banks are emerging in endlessly. But there is a common problem that you need to bring the supporting data cable to charge the device. IWALK allows you to charge the device without data!

IWALK calls this kind of power bank Pocket Treasure, and now it has reached the third generation. With super small size and weight, the packaging design is also more interesting. A small window in the shape of a battery is opened on the shell, and the red battery in the package is taken out to change color.

You can see the words "Call when you plug in", which means that you can charge the device when you plug it in without switch.

The iWALK provides a total of three types of interfaces, including microUSB, Lightning, and USB Type-C. What I got is the micro USB interface, which is still widely used at present. Although the pros and cons should be considered when inserting, most digital products have not been popularized to the USB Type-C stage, so microUSB should be more practical.

The 3300mAh 5V/1.5A output is much smaller than that of an ordinary 5000mAh power pack. And there are four colors to choose from: white/pink/black/green. This one is black and will not be eliminated. The surface is also treated with anti slip treatment, which looks very pleasant.

On both sides of the iWALK are USB charging ports and a physical switch. This design is similar to that of ordinary power packs.

The logo of the positive iWALK is still quite eye-catching, and the brand image needs to be mentioned frequently to be remembered. There are three LED lights on the back of the logo, one of which shows about 33% of the power. When charging and discharging, they are both displayed, which is more intuitive and reasonable.

The charging head of the device uses a protective sleeve with good texture, which does not cut hands and is not very hard soft plastic. In addition, the card is just right and should not fall off. However, the extra head may hinder the storage of some small bags. It seems that there is still room for development. We can consider making an expansion interface for the next generation.

After all, the charging effect is good. After all, the power is 1.5A. Although the fast charging effect of half an hour can not be reached after 5 minutes of charging, the emergency response is very good. And there is no need to plug and charge with data lines.

In fact, it is also possible to use this to charge the iPhone. It requires such a connector to charge easily. In the future, the USB Type-C adapter can also continue to be used. It just needs to grow a little, which affects a certain degree of aesthetics. However, it is easier to hold it in your hand. There is nothing unsuitable and it should not fall off.

Of course, there is no problem in charging other devices with the same microUSB interface. The battery capacity of these small earphones and speakers is also relatively small. The 3300mAh power pack can fully charge them at one time. When you are out of the door and suddenly have no power and no data cable, you need to have an iWALK nearby.

Advantages: small and durable, high appearance, good battery capacity, more convenient without data cable charging, and compatible with multiple interfaces to support charging of multiple devices.

Disadvantages: The extra charging plug can't be retracted, which is a bit of a hindrance. The protective cap pulled out may interfere with the following key operations for some Android phones.
