In the age of smartphones, it’s no sense to carry a calculator with you, but the following old-school calculator is an exception because it doubles as a 6000mAh power bank.
This is a vintage and practical portable charge that measures 85 x 146 x 20mm and weights 176g. As we can see from the images, the power bank is also a workable old-school calculator with a leather cover in order that you can use it to make calculations without needing to take out your smartphone or turn your computer on. Moreover, the calculator power bank comes with a 6000mAh backup battery. Using its built-in 1A and 2A USB charging ports, you can conveniently charge your smartphone, tablet and other mobile devices on the go, and a LED flashlight offers illumination in some emergent situations.
The calculator power bank is priced at $38 USD. If you like the design, head to Brando for more details. Additionally, if you want other options, you may like to check the cassette tape shaped power bank and more by following tags.
