Kickstarter has produced another gadget aimed squarely at travelers who hate carrying extra bricks: Solly is a 20,000 mAh mobile battery that also works as a wall charger, adds a built-in folding plug, and even squeezes in a solar panel. The pitch is simple enough to understand and ambitious enough to make you squint at the spec sheet.
The numbers are the main attraction. Solly is rated at 74 Wh, claims 300 W of total output, and offers two USB-C ports that can each deliver up to 140 W, plus a USB-A port rated at 20 W. That puts it well beyond the usual phone-first power bank and closer to the kind of accessory people would use for laptops, tablets, and the inevitable pile of devices that shows up on a trip.
Solly battery specs and charging options
The device can charge itself either through the built-in plug directly from a wall socket or over USB-C at up to 140 W. The package also includes a USB-C cable that doubles as a carrying strap, which is exactly the sort of small design trick that makes a product feel thought through instead of just crammed full of features.
- Capacity: 74 Wh, or 20,000 mAh
- Total output: 300 W
- USB-C ports: up to 140 W each
- USB-A port: up to 20 W
- Charging: wall plug or USB-C up to 140 W
Why the solid-state battery matters
Solly’s other headline feature is a solid-state battery, which the makers say is safer than conventional lithium-ion packs, more resistant to mechanical stress, and less prone to overheating. That is the kind of claim that matters more in a travel product than in a desk accessory, because luggage, drops, and temperature swings tend to expose mediocre battery design very quickly.
There is also a built-in solar panel for charging the solid-state cell. It is a nice extra rather than a magic trick, because solar input on a compact device rarely replaces wall charging, but it does give the product a cleaner survivalist pitch than yet another plain black power brick.
Price, launch timing, and crowdfunding traction
The crowdfunding campaign starts at $90, with first deliveries promised for August. Solly has already pulled in more than $400,000, which suggests backers are happy to pay for convenience when the product combines several separate accessories into one body.
If it ships as promised, Solly could appeal to a crowded but predictable audience: frequent flyers, remote workers, and anyone tired of packing a charger, a power bank, and a cable separately. The real test will be whether the battery lives up to the solid-state hype and whether the built-in plug makes the whole thing genuinely practical instead of just impressively overstuffed.
