Fantech S3 10000mAh Portable Power Bank

Fantech S3 10000mAh portable power bank

The Fantech S3 10000mAh power bank is a simple, reliable backup battery for everyday use. It’s slim (17mm thick), it comes in four colors, and it can charge five devices at once. If you want a power bank for class, office, or long trips home during Eid, without paying for features you won’t use, this one makes a lot of sense.

Charge five devices together

The S3 has two USB-A ports along with USB-C, Micro USB and Lightning outputs. That covers iPhones, Android phones, earbuds, smartwatches and older Micro USB gadgets. Every output runs at 5V/2A, so it’s best suited to steady everyday charging rather than super-fast top-ups.

Know how much charge is left

An LED display on the front shows the remaining power, so you aren’t caught out with an empty power bank halfway through the day.

Two ways to recharge

You can recharge the S3 with either a Type-C or Micro USB cable (5V/2A). Whichever charger you have at home or in the office will probably work.

Slim, light and airline safe

At 141 x 68 x 17mm and around 215g, the S3 slips easily into a pocket, sling bag or backpack. Its 37Wh rating is well under the 100Wh airline limit, so you can carry it in your cabin bag. Built-in safety protection keeps your phone and the battery safe while charging.

Pick your color

Choose from Black, White, Blue or Purple. The Purple and Blue versions stand out nicely if you like your gadgets a bit more colorful.
