Slim 10 000 mAh power bank

The Fonus Slim is a 10 000 mAh portable battery with two USB outputs rated at 2.1 A. It ships with a built-in 8-pin iPhone cable plus separate Type-C and Micro-USB cables so you can charge an iPhone or iPad and an Android device at the same time. An LED indicator shows the remaining charge level.

Who this suits and who should look elsewhere

It suits people who want a single compact pack that covers both Lightning and USB-C devices without carrying extra cords. It is not for buyers who need more storage than 10 000 mAh or who require higher output for larger tablets or laptops.

Capacity and headroom

The 10 000 mAh cell comfortably provides multiple full charges for typical smartphones such as the Samsung Galaxy Note9 or J7 2018. It runs out when you try to power devices that draw more than the 2.1 A limit or when you need several days of heavy use without access to a wall socket.

Questions about this item

What cables do I need to charge the power bank itself?

The unit includes a built-in 8-pin iPhone cable, a separate Type-C cable and a separate Micro-USB cable; use the Type-C or Micro-USB cable with any 5 V USB charger to recharge the power bank.

Can I charge a Galaxy Note9 and another phone at the same time?

Yes, the two USB ports deliver up to 2.1 A combined, so a Galaxy Note9 (2018) and a second device can charge together.

How do I know the power bank is charging my devices correctly?

The LED indicator shows the charging status and remaining battery level while the power bank is in use.
