The Ulefone Power 3S is one of Ulefone's newest big battery smartphones, and the company has decided to show off its reverse charging feature by releasing a new promo video. If you take a look at the video which is embedded down below, you will be able to see one phone charge four other devices, in this case, the Ulefone Power 3S. Now, in order to use this functionality of the Ulefone Power 3S, you will need an OTG cable and a USB hub.
That being said, after you plug everything in, all you have to do is connect all four devices to a USB hub, and you're good to go, those devices will start charging from the Ulefone Power 3S' power pack. Speaking of which, the Ulefone Power 3S comes with a 6,350mAh non-removable battery, and thanks to its reverse charge functionality, you can actually use it as a portable power pack, next to it being a smartphone, of course. The Ulefone Power 3S actually comes with a compelling set of specs as well, especially considering the phone's price point. This phone features a 6-inch fullHD+ (2160 x 1080) display, along with 4GB of RAM and 64GB of native storage. The device is fueled by the Helio P23 64-bit octa-core SoC by MediaTek, while Android Nougat comes pre-installed on the device, though Android 8.1 Oreo is coming. The device also comes with 5V/3A quick charge functionality, while you will find four cameras included on the device, 16 and 5-megapixel snappers are included on the back of the phone, while 13 and 5-megapixel cameras sit on the front side of this smartphone.
The Ulefone Power 3S is made out of metal, while it sports a rear-facing fingerprint scanner. Its bezels are not thick at all, while the device features a Type-C USB port on the bottom. This handset actually looks identical to the Ulefone Power 3S, and it's slightly less powerful than the Power 3, but it's also considerably more affordable. If you're interested in purchasing the Ulefone Power 3S, you can now grab it for only $167.99 on AliExpress, as the device is currently discounted, so it's probably the right time to pick one up.
