The Portable Charger That Powers Your Phone, Camera, Laptop and Jumpstart Your Car

River Bank Powerbank

This portable charger can handle most of your gadgets, and even jumpstart your car.

River Bank, the brainchild of US-China company EcoFlow, is probably something a lot of on-the-go people need right now.

This is not just your regular run-of-the-mill portable charger, it’s a heavy-duty one that has a modular approach to suit different needs. It holds its charge for more than a year, and it is possible to take on airplanes.

The Federal Aviation Authority (FAA) requires portable chargers or battery packs to have a limit of 100Wh capacity. EcoFlow believes that they were able to find a way around this by breaking the charge down into modules.

River Bank’s main pack includes two USB outlets, two USB-C outlets and Qi wireless charging. For those who want to add more functions, two additional modules can be added. One for AC ports and another to jump-start cars. These two modules can also be stacked unto the main module to increase capacity or recharge it.

With the AC port module, virtually any device with a plug can be charged such as drones, cameras and laptops.


The River Bank portable charger’s main module is priced at $199. If you want the additional modules, you have to fork out an additional $99 for each one. However, you won’t be able to get this on the market just yet.

Currently, the heavy-duty portable charger is already in production but will ship out to backers from Indiegogo in August. More information are available here.




Charge your dead smartphone with your shirt!

One of the biggest problems that technology has, is its inability to run without power. People who develop slow draining batteries only allow us to use our devices for a period of time. Still, it gets drained and we are left with a paper weight down our pants.

Still, a number of individuals try to alleviate our problems. The said persons try to invent ways on how we could power up our dead smartphones.

One such device is the work of two engineers from the University of South Carolina. The two developed a way to charge our devices with what we usually have with us when we’re out, a t-shirt.

Xiaodong Li who was a part of the team said, “By stacking these supercapacitors up, we should be able to charge portable electronic devices such as cellphones.”

Li and Lihong Bao bought a shirt from a store, soaked it in fluoride, dried it, then baked it in an oven without oxygen.

They then examined the shirt and discovered that the fibers of the cotton had turned into activated carbon. They also discovered that activated carbon can store electrical charge as a capacitor.

They then added a layer of manganese oxide to improve the shirt’s electricity-storing capability.

Li said that, “This created a stable, high-performing supercapacitor.”

We might be seeing this charged shirts anytime in the future. Let’s just hope that it will not electrocute us.
