When you buy a power bank, it usually comes with a charging cable in the box, but what you won’t find is a power brick/charger to charge the power bank when it is low. If you don’t have a charger, you will have to buy one to charge the power bank. Even those who have one (for their phone) usually end up buying an extra they can use to charge their power bank. A company called Bull has a nifty power bank that doesn’t need a separate power brick to charge.
The latest Bull power bank not only has a
built-in cable for charging your device but also has a built-in power brick. To
charge the power bank, all you have to do is unfold the plug and connect it to
a wall socket, and it begins to charge. This design means that the power bank
doesn’t have any ports. There is no output port since it already has a charging
cable. There is also no need for an input port since it has a built-in charger.
With a cable and charger built into the
power bank, you don’t need to take a charging cable and a wall adapter with you
when going on a trip. You can also plug in your phone while the power bank is
connected to a wall outlet and the built-in charger will simultaneously charge
your phone and the power bank.
Another neat feature the Bull power bank
has is a cable winder that holds the built-in cable in place. Owners will be
able to unwind the required length they need without the rest getting in the
way. The power bank has four LEDs to show the remaining power level. It also
has a power button on the side and a lanyard hole at the bottom corner.
The Bull power bank has a 10000mAh battery
capacity and comes in Coral and Gray. Buyers can choose between a model with a
USB-C cable or one with a MicroUSB cable. Sorry iPhone owners, there is no
version with a lightning cable. Regardless of the version you choose, the price
tag is ¥ 152 (US$ 23). You can pick up a unit on JD.com.
