Shargeek Storm 2 and Storm 2 Slim are NOT your typical power banks

If you’re on the hunt for a high-quality power bank that’s unlike any other, look no further than the Shargeek Storm 2 and Storm 2 Slim.

These devices are not your average run-of-the-mill power banks – with their clear shells showcasing a stunning array of internals that give off a Steampunk/Cyberpunk vibe, they’re sure to appeal to any tech enthusiast.

But don’t let their cool design fool you – after using both models for two weeks, I can confidently say that they are workhorses that pack a serious punch.

These power banks are more than just a last-minute juice boost to call an Uber home – they’re powerful machines that can keep your devices charged even when you’re off the grid.

Storm 2 Design

When you first unbox these power banks, you’ll notice how solid they feel. These are devices that are built to be used, not just to sit on a shelf and look pretty. The clear outer shells reveal interesting and functional-looking capacitors, chips, and massive batteries that are sure to impress.

One standout feature of both the Storm 2 and Storm 2 Slim is the color display screen, which shows you how much juice is stored in the battery as well as the input and output wattage. This feature is incredibly useful, as it allows you to see not only how much battery capacity the power bank has but also how much charge is going in and out of the device. With this information, you can be confident that your devices will charge fully and quickly.

It’s worth noting that traveling with these power banks might raise some eyebrows at TSA security, as they do look like devices that could go BOOM. However, both models are airline safe and have a battery capacity lower than 27,027mAh (100 watt-hours), which means they can be taken on a flight legally and safely.
