Electric energy has become such an important resource that we are constantly innovating to transport it everywhere. With more greedy phones and electronic accessories, we need a tool to make us more independent. One of the accessories we tested is the ravpower external battery, also called powerbank, with a capacity of 22000 mAh.
I personally used a brand of powerbank for 3 years and it never disappointed me. In this article, we will talk about the RavPower Model RP-PB052 external battery with a capacity of 22000mAh. We begin our first article in the test section with the powerbank ravpower.
The iSmart technology allows the external battery to automatically adjust the intensity of the current while charging your device up to 5.8A. Although ravpower charges devices very quickly, it is not compatible with devices equipped with Qualcomm Quick Charge technology.
It should be noted that the power bank automatically deactivates its ports so as not to overload your device as soon as it is full. So when I charged my phone until the early hours of the morning, I almost never saw the device 100% charged. In my opinion this is a good measure, so as not to tire the phone battery.
I also found that this battery charges my devices faster than when I plug it into the mains. I haven't tested it with enough phones to check my prints.
The capacity of the ravpower external battery is 22000mAh (milliampere hours). What does this mean in concrete terms:
- If you have an IphoneX, you will be able to charge it 4.9 times at most.
- With a Galaxy s8, it can be charged 4.4 times.
- And finally an ipad mini 4, the loading can go up to 2.2 times.
The ravpower powerbank recharges completely after 10 or 11 hours of time. Generally I plug it into the sector from 20 p.m. then unplug it when I need it the next day. The external battery can be charged via the USB port of your computer and the mains.
I often use ravpower with my Galaxy Note 9. I fully charge my smartphone between 4 and 5 times before charging the powerbank.
Capacity and technology are good, but how long can they be used without fail?
The Ravpower external battery is designed to retain between 70 and 80% charge after 500 charge-discharge cycles.
Upon purchase I received a lifetime warranty. For 3 years of use I have not had any problems or malfunctions. However, I cannot tell you the number of times that I have loaded and unloaded. These are things that do not count is not it?
Fire protection: The powerbank is protected by a fire-resistant shell. This shell according to the manufacturer complies with the UL94 V-0 standard. A standard used for Mercedes-Benz, BMW cars and certain luxury cars.
Battery protection: On the manufacturer's site, the batteries of the power bank ravpower are separated by 10 layers of protection to ensure the transmission and reception of electricity.
Protection of tedidev.com: I never opened the power bank or attempted to set it on fire to check. Don't do it either.
The price :
A very, very important question. It is nearly 30000 f cfa on the original site. When I bought it in 2017, I spent almost 21500 CFA francs. To conclude, I will say that it is affordable.
Where to find the ravpower external battery?
You can order this powerbank on the manufacturer's website https://www.ravpower.com/ . The link will take you directly to the product page.
On the other hand, I ordered it in amazon.fr . By returning on the same link of my order, the color and the price had changed. So I advise you to search for yourself.
Speaking of color, you have the choice between red, white, black and dark blue.
