GUXON Cube Solid-State Power Bank｜Twin Pack

"Do you have this problem too?" Power banks that are thick and heavy and will not fit a small bag / forgetting your cable and not finding a Lightning charger anywhere / news stories about power banks catching fire

We know safety matters to you, so we switched to a solid-state battery that turns the leak-prone, flammable liquid into a stable jelly-like gel.

We have also met China's new 2026 safety standard ahead of time — top-tier protection for your bag and your family, reducing the risk of a power bank going out of control.

The upgraded solid-state battery runs cooler than a liquid cell and will not ignite or explode if punctured. Even if it is damaged, it discharges normally and charging stays steady and dependable.

With a 90% gel solid-state electrolyte, most of the liquid inside the cell has been replaced. With so little liquid, even if the power bank is crushed out of shape or pierced by something sharp, flames, explosion or leakage are unlikely.

The latest solid-state battery technology addresses the two biggest pain points of conventional lithium cells: swelling and combustion.

Even after a heavy impact or in extreme heat, the risk of thermal runaway and fire is greatly reduced. With no free-flowing liquid inside, gas generation is suppressed — no more battery swelling, and a much longer service life.

Puncture testing follows China's upgraded standard introduced in April, which is stricter than the old one across puncture speed, needle specification and pressure duration, raising the bar for battery safety validation.

The stacked construction spreads current across many layers instead of concentrating it in one path — like ten people carrying 100kg instead of one person struggling alone. The cell runs cooler and is far less prone to swelling.

Refined again on the outside, using a bespoke cell to make the Cube as small as possible: 10% smaller than the previous generation, sized to fit one palm and to slip into a small bag without a second thought. Travel light!

Type-C and Lightning cables are built into the body, double-braided so they hold up. No more digging through your bag for a cable or borrowing someone's charger — pull it out and charge, in a second.

While your phone charges, the Cube's braided cable doubles as a wrist loop — put a finger through and it will not drop. The double braid is strong and wears well.

Type-C delivers up to 22.5W, taking the iPhone 17 Pro to 50% in around half an hour. Lightning delivers up to 20W.

With a device connected, hold the button for about 3 seconds and the Cube enters trickle-charge mode — handy for low-draw devices, and it will not switch itself off during long sessions, solving the usual problem of a power bank shutting down when it cannot detect a load.

10,000mAh is enough for most phones 1.5 to 3 times over, covering a full day of light to moderate use. Navigation, photos, looking things up — no more hunting for a socket in a hurry.

Alongside the two built-in cables, the Cube has a separate Type-C port for input or output, so you can use your own cable to charge whatever you like.

20W PD fast-charge output, matched to the needs of the latest iPhones and other mobile devices.

The Cube is certified by Taiwan's Bureau of Standards, Metrology and Inspection. Its function, performance and battery design meet the required safety standards, so it will not cause leakage current, fire or other hazards in use.

Charging is a statement too: black for composure, silver for crispness, milk tea for warmth, cosmic orange for character, pink for sweetness. In GUXON's usual design language — playful and young, an accessory in the hand as much as a power bank.
