Most of the items around you now have to be recharged after each day of use, so the backup battery has gradually become an indispensable item in each person’s backpack or bag.
When talking about power banks, we often pay attention to the capacity, shape, plug standard or fast charging technology attached. However, today Webuy will introduce a battery that at first glance, you will hardly imagine how it works as well as how to ‘assemble’.
Experience “One-of-a-kind online shopping”
Charge your phone from the wire connecting 2 AA batteries – good deal or bad deal?
Simple outer box, no manufacturer name or “charger” parameters
There is only one connecting cable inside, there are no manuals
And here is the result after having “assembled” in full. Looks like a series circuit in the class 5 engineering …
But surprisingly, the phone receives real power, maybe the power bank is so simple?
But when using the power metering application, it only has 150mA, this level is not even enough to maintain the operation of the device, let alone charge the battery.
Webuy tried with another backup battery, the results showed that the input power is almost … 10 times stronger than the “battery connector” …
Is it worth the money?
Of course the answer would be no, and Webuy threw the product away in just 15 minutes of experience.
Through this, we can draw from experience that … do not rush to believe the sales ads on social networks. You will never be guaranteed safety, let alone the warranty. With electronic devices, especially power sources, a fire and explosion is very easy to encounter, so Webuy advises not to spend time and money on these useless products.
Even the price of this “backup battery” is up to 180,000 VND, this amount is enough for you to buy yourself a “genuine” rechargeable cable, a famous brand and completely assured of quality.
