Real-World Performance
In testing, the Storm2 lived up to its promised potential in most areas. The 25600mAh battery has huge capacity – enough to charge a phone over 10 times or a laptop multiple times.
The 100W maximum input allows the giant battery to recharge in just 1.5 hours when using a 100W USB PD charger. This is incredibly fast for a battery of this size. The pass-through charging also worked flawlessly, allowing you to recharge the powerbank and connected devices simultaneously.
The output capacities of the ports successfully powered all connected devices in testing. The 100W USB-C port can fast charge compatible laptops at their maximum rate. And the advanced charging protocols like QC 3.0 and PD allowed fast charging of smartphones from brands like Samsung, Google, and Apple.
The "Energy Storage Management OS" display provides detailed real-time monitoring of power input, output, voltage, current, and temperature for the battery and each port[1]. This gives you an impressive level of insight into the powerbank’s operation. The stats matched up accurately with measurements from testing equipment.
The cyberpunk-inspired transparent case, yellow cable and accents, and bold angular design give the Storm2 plenty of futuristic tech flair. The plastic case feels sturdy, even with little flex when pressure is applied.
Downsides
The Storm2 does come with some downsides to consider.
Firstly, the 590g weight is quite hefty for a portable powerbank. While not prohibitively heavy, it makes it less ideal for packing light.
Secondly, while advanced safety protections are in place, the battery did get concerningly hot when fast charging in high ambient temperatures. Caution is advised when quick charging in hot environments.
It doesn’t support fast charging protocols for Xiaomi phones, or SuperVOOC charging for Oppo/OnePlus/Vivo/Realme phones. It can charge upto 30W in their case.
Finally, the $199 price is quite expensive for a powerbank. The premium price tag places it out of reach for many casual users.
Who is it Best Suited For?
The Storm2’s combination of ultra-high capacity, blazing fast charging, and vibrant display make it ideally suited for several user profiles:
Tech enthusiasts – The advanced feature set and cyberpunk aesthetic will appeal to tech geeks who want the latest and greatest gadgets. Fast charging their multiple devices is a priority.
Frequent travelers – The huge battery can keep devices powered up for days of travel. Fast recharging in 1.5 hours at the airport or hotel is a major bonus.
Professionals and power users – The 100W USB-C port can rapidly charge high-powered laptops at maximum speeds, ideal for professionals. The four ports allow charging multiple devices at once, meeting power users’ needs.
Anyone with multiple devices – With 4 ports, it can charge multiple devices simultaneously. The 25600mAh battery has capacity to spare.
Conclusion
With its massive battery, ludicrously fast charging, vibrant display, and cyberpunk design, the Shargeek Storm2 lives up to its promise as a cutting-edge portable powerbank. Real-world use shows it can quickly charge just about any device at maximum speeds thanks to advanced charging protocols and 100W output. Downsides like the premium price and large size do exist, but are reasonable trade-offs for the exceptional performance and features on offer. For gadget lovers, frequent travelers, mobile gamers, and professionals who demand both style and functionality, the Storm2 delivers.
