Sharge Shargeek Storm 2 Power Bank 100W

The Sharge Shargeek Storm 2 is a 25,600mAh power bank built for people who charge laptops, not just phones. Its transparent polycarbonate shell, framed in aluminium, puts the eight Samsung lithium-ion cells and the circuit board on display, and a built-in IPS smart screen shows live input and output voltage, current, power and remaining capacity instead of a row of guessing-game LEDs. The headline figure is real output: the main USB-C port delivers up to 100W on its own, enough for full-speed charging of most USB-C laptops, and an adjustable DC port covers equipment that USB cannot.

Key features

• 25,600mAh, 93.5Wh capacity from eight Samsung lithium-ion cells
• USB-C1 input and output up to 100W for full-speed laptop charging
• Four ports: two USB-C, one USB-A and one adjustable DC port
• DC output adjustable from 3.3V to 25.2V for non-USB equipment
• IPS smart display showing live voltage, current, power and battery status
• Transparent shell with aluminium frame showing the internal cells and board
• 93.5Wh rating, below the 100Wh threshold airlines use for cabin batteries

Four ports, properly rated

Port ratings matter more than port counts. On the Storm 2, USB-C1 is the heavy lifter: it accepts and delivers 5V, 9V, 12V and 15V at 3A, and 20V at 5A, for up to 100W in either direction, so the same port that charges a MacBook-class laptop at full speed also refills the power bank itself at up to 100W. USB-C2 delivers up to 30W for phones and tablets, the USB-A port delivers up to 18W for older devices and accessories, and the DC port works in both directions, taking 5 to 24V input or delivering an adjustable 3.3 to 25.2V output at up to 3A for routers, cameras, LED panels and other barrel-jack equipment. Multiple ports can run together for a laptop-plus-phone-plus-accessory travel setup, with power shared intelligently between them.

The display is the point

Most power banks report their state with four LEDs. The Storm 2’s IPS display shows what is actually happening: per-port voltage and current, total power draw, battery percentage, temperature and estimated remaining time. That turns charging from an act of faith into something you can verify — you can see whether a laptop has negotiated full power, whether a cable is limiting the rate, and how long the bank will last at the current draw. The screen and the transparent casing are the design idea working together: this is a power bank for people who like to see the engineering.

Capacity and travel

The 25,600mAh capacity is rated at 93.5Wh, deliberately just under the 100Wh limit that airlines apply to spare lithium batteries in cabin baggage, so the Storm 2 is sized for carry-on travel with laptops. In practical terms that capacity translates to roughly two charges for an ultraportable laptop, or many charges for phones, cameras and handheld consoles, depending on the device and conversion losses. The body measures about 151 x 59 x 46 mm, so it packs like a small paperback rather than a brick, and the aluminium end frames take the knocks that a clear shell should not have to.

If your bag already carries a USB-C laptop, a phone and camera or audio gear, the Storm 2 replaces two or three lesser chargers with one bank that can prove, on its own screen, exactly what it is delivering.
