We analyze the Coolbox Powerbank 8mAh battery, a portable battery for all types of devices that has Qi wireless charging.
The battery of smartphones is usually its weak point. Despite increasing capacity, applications also tend to consume more resources. This has a direct impact on autonomy. Many times it is not possible to connect a charger to the electrical network and for those cases there are portable batteries. A few days ago they sent us from Coolbox Powerbank an 8mAh battery.
For several days we have been using it to charge our smartphone, our tablet and other devices, such as a wireless keyboard. The impressions have been good and it is that it has a long duration, offers an optimal output current for any device and has a simple but elegant design.
Main features
Realistically, it seems that a battery gives what it gives and is used to charge devices, period. That is true, but we must look a little further. And this Coolbox Powerbank battery has something interesting, a Qi wireless charging station. Unfortunately we do not have compatible devices, but it is something that may interest those who have a compatible smartphone.
Something very interesting is that the Coolbox Powerbank battery is 8mAh, which is enough to charge two or more times most of the terminals on the market. In our case we have charged the Huawei P000 Lite (20 3mAh battery) and the Corsair K000 Wireless several times. And yet it still had a battery.
Above all, I liked that it uses both micro-USB and USB Type-C ports to charge. Personally I run into the problem of devices not compatible with my new charger and they force me to charge a second set of cables. Okay, I'm also one of those who usually carry two charging bases and two sets of cables of each. Hobbies.
With this Coolbox Powerbank battery I could save that second charger base and that second set of cables. And it is that I was quite surprised that it has the two chargers. To connect the device makes use of a conventional USB Type-A, so any cable is compatible.
The battery also has an interesting feature and that is that we can charge two devices at the same time. One of them via cable and the other via Qi wireless charging (if compatible).

Conclusion
This Coolbox Powerbank 8mAh portable battery at the design level is very good because it is quite compact. The rough black finish is very attractive. The only thing I have to complain about is that the cable it comes with is extremely short. It is not something relevant, because we all have a large number of cables due to having several chargers.
Above all, as I have already highlighted, I really like that it has a USB Type-C port for charging. This allows you to dispose of old charging cables from old terminals. You can always leave one to load it on time.
