Description

With the BlueBuilt Power Bank 20,000mAh, you can easily charge your smartphone or tablet on the go. You'll have enough capacity to charge your smartphone 4 times, or charge your tablet 2 times. If you're on the go with someone, you won't have to argue about who gets to charge first. Because thanks to the 2 USB ports, you can charge 2 devices at the same time. Both ports provide 10W power. This isn't enough for actual fast charging, but charging is still pretty fast. On top of that, this is enough power to also charge larger devices such as tablets or your iPad. This BlueBuilt power bank is sturdy and lasts long. And you even get a 5-year warranty on it. The power bank comes with a USB-A to USB-C cable.

Fantastic product for a low price

  • Charge phone quickly
  • Beautiful appearance
  • Cheap for a fantastic power bank
  • Power bank charges slowly

I use it every day for my work as a bicycle courier. I work long shifts and always have google maps open so I have to charge my phone often, after charging my phone 3 times, the power bank is half empty. A great purchase for me

Neat price / quality

  • Large capacity
  • Solid construction
  • Size vs. capacity
  • According to manual only 2 USB-A charging ports for devices

Neat power bank for a decent price, it is described here that it has 3 charging ports. However, according to the manual, only the USB-A are charging ports and the USB-C is for charging the power bank itself. Charging at 1A takes 20 hours, at 2A 10 hours. Fast charging is a nice luxury that you pay more for. Well worth considering. The power bank feels solid and comes in a cover. Nice flexible charging cable included (USB-C).
