With the development of society and the popularity of mobile phones, our dependence on mobile phones is also very high. Insufficient battery is one of the biggest problems facing smart phones today. In order to avoid this, we must also bring a power bank when we go out. However, the size of the power bank is very large and it is not convenient to carry it. A team here invented a portable power bank.
This chong is a super powerful portable battery. It looks like a small ball of thread, but it actually contains charging equipment.
When we encounter an emergency and the mobile phone needs to be charged urgently, this small thread group is our best choice. It can support the use of the mobile phone for 3 hours on a single charge.
We simply plug the portable battery into the mobile phone, and we can charge it anytime and anywhere, and we will not be affected by making calls, navigating maps, sending text messages, and doing anything. What's even more amazing is that it is also very smart, and can decide whether to give priority to the phone by automatically detecting the battery power.
Don't look at the small size of the portable battery, but its power in the body is absolutely sufficient for us to use! Its 700mAh battery can support 8 hours of music playback, 3 hours of calls, and 2.5 hours of Internet access.
Not only that, the charging speed of the portable battery is also very fast! Compared with ordinary USB interface cables to charge mobile phones, the speed of portable batteries is twice as fast.
And the appearance design of the portable battery is also very beautiful. When not in use, we can hang it on the key chain as an ornament, or hang it on the bag, or on the jeans. The portable battery is also very useful. Convenient, you can help anytime, anywhere, and solve the problem of our mobile phones without electricity.
I believe this portable battery will be welcomed by everyone!
