20,000mAh Capacity & Universal Compatibility - 20,000mAh is the industry standard for heavy-duty power banks. Packed into a dense palm-sized solution, the Storm 2 Slim stands out with its simplicity and ease of use. Just 2-ports (which are also compatible with all USB-C and USB-A standards) for full-speed plug-and-play.
Blazing 130W Output - Power anything from your mobile device to a 16' Macbook Pro all at full speeds. Running on next-gen 21700 battery cells, these are incredibly efficient at producing raw power all within its small size. For context, these same batteries are also used in Tesla Cars and Nitecore's larger Power Stations.
IPS Display Screen & Control - Toggle your own power settings, charging speed through all ports and even device temperatures, all in real-time at one place. No more second-guessing how much power is passing through.
Multiple Safety Protections - With great power comes great responsibility. The Storm ² Slim is equipped with multiple safety protections such as overcharge protection, over-temperature protection and short-circuit protection, ensuring the safe charging of all your devices.


The Storm² Slim is the compact power bank of the future.
There are many brands in the market right now that market their power solutions to be truly usable and powerful, but many fall short due to inferior battery and circuit components.
Without proper tools like a voltmeter to tell what actual charging speeds are, you most likely won't even know if a powerbank is performing as advertised.
The Storm² Slim sets itself apart, by using only the best materials.
Housed in a transparent fireproof case, using next gen 21700 batteries along with universal compatibility with all charging standards like PD and QC.
It's travel safe and has all the information you need from the IPS display to keep your devices working in tip top condition.
If you've been looking for the most compact, high capacity power bank that's also travel safe, don't miss out on the Shargeek Storm² Slim. It's going to be the only powerbank you need.
