Elecom DE-C102 power bank, Digi Mart USA News (Japan): Japanese electronics maker Elecom has announced the DE-C102 series, a 10,000mAh portable battery that the company says can charge a phone twice on a single charge. The unit weighs just under 200g, according to the publisher report, and was announced in Japan on November 11.
The most notable feature is the battery design. Elecom uses a semi-solid lithium-ion battery with a gel-like electrolyte, which the company says reduces the risk of leakage and improves thermal stability.
Elecom also claims the power bank can support around 2,000 charging cycles, roughly four times the cycles of conventional lithium-ion batteries. These figures are manufacturer claims based on standardized testing and have not been independently verified for long-term use.
Elecom rates the device for supplying power at temperatures between -15°C and 45°C. A battery-health indicator changes color according to accumulated charging cycles, which the company says can help owners judge when replacement may be needed.
The USB-C port and built-in cable support charging at up to 20W via USB Power Delivery, or 22W with PPS. When charging multiple devices at once, the combined output drops to 21W.
The unit also includes a low-current mode for small accessories such as earbuds, fitness trackers and smartwatches, and supports pass-through charging. The DE-C102 series is scheduled for release in mid-November in black, white and a white-and-black Shiro-chan edition.
Its listed Japanese retail price is ¥7,480, approximately $48.
