Owltech is rolling out four magnetic wireless power banks built around semi-solid-state cells. The lineup runs from a 5,000mAh model just 6.7mm thick to 10,000mAh models with a monitor that shows remaining charge and cycle count. All four are due in late August, with street prices expected to land between roughly 9,000 and 12,000 yen.
Swapping the Liquid Electrolyte for a Flame-Retardant Gel
What ties the four models together is the semi-solid-state cell. A conventional lithium-ion battery uses a liquid electrolyte; a semi-solid-state cell replaces it with a flame-retardant gel. That makes leaks far less likely and reduces the risk of ignition from an impact or an internal short.
The benefit is not limited to safety. All four models are rated for roughly 2,000 charge cycles and carry a 1.5-year warranty. Power banks are the kind of accessory that tends to swell or lose capacity within a few years, so a longer service life translates directly into a lower effective cost. Owltech has been steadily expanding its semi-solid-state range over the past year, and these four models fill out the wireless-charging side of that lineup.
All four are sold through limited retail channels. The model numbers are DQC-PBM5002J, DQC-PBM10002J, DQC-PBM10003J and DQC-PBM10004J. The first three come in black and white, while the leather-look DQC-PBM10004J is offered in black and caramel brown.
The Ultra-Thin Models, Starting at 6.7mm
The DQC-PBM5002J and DQC-PBM10002J are the slim pair. The 5,000mAh DQC-PBM5002J measures roughly 71 x 6.7 x 100mm, keeping the body under a centimeter thick. Stuck to the back of a phone and slipped into a pocket, it adds little to the feel in the hand.
On the charging side, magnetic wireless charging compatible with MagSafe and Qi2 tops out at 15W, while the USB Type-C port delivers up to 20W over USB PD. Using wireless and cable together caps the combined output at 15W. Input runs at up to 18W PD, and a full recharge from empty takes about 1 hour 30 minutes. Rated output capacity is 2,800mAh at 5V, roughly one full smartphone charge. A 30cm USB Type-C to Type-C cable and a warranty card are included.
The DQC-PBM10002J doubles capacity to 10,000mAh and measures about 11.7mm thick. Even with twice the cells, that still counts as slim for the 10,000mAh class.
Models With the Battery Monitor
The DQC-PBM10003J and DQC-PBM10004J add a display Owltech calls the reassurance monitor. Alongside remaining charge, it reports the number of charge and discharge cycles so far, plus the wattage flowing in or out. It effectively lets the owner watch the long service life that the semi-solid-state cell is meant to deliver.
The DQC-PBM10003J has two USB Type-C cables built in. The body measures roughly 71 x 21.4 x 109mm and holds 10,000mAh (36Wh). The first built-in cable and the USB Type-C port handle 18W PD input and 20W PD output, and PD-PPS passes through as well. The second cable supports 18W QC. Between the two cables, the port and wireless charging, up to 4 devices can be topped up at once. Since there is no need to carry separate cables, it should be useful when several people need power away from a desk. Rated output capacity is 6,700mAh at 5V.
The DQC-PBM10004J wraps the same 10,000mAh capacity in a leather-look finish, with magnetic wireless charging up to 15W. It is the option for anyone who would rather not hold metal or bare plastic.
Pricing and Availability
All four models are scheduled for late August. Expected street prices are around 9,680 yen for the 5,000mAh DQC-PBM5002J, about 12,180 yen for the ultra-thin 10,000mAh DQC-PBM10002J, and roughly 10,280 yen each for the monitor-equipped DQC-PBM10003J and DQC-PBM10004J.
Measured against the usual 10,000mAh power bank, that is on the expensive side. Factor in the semi-solid-state cell and the roughly 2,000-cycle rating, though, and the cost per cycle looks different. With battery fires surfacing repeatedly in the news, more buyers are treating cell safety itself as a selection criterion, and the pricing reads as a response to that shift.
All four carry PSE certification, and Owltech says they meet the carry-on baggage rules of most airlines.
Summary
Owltech's four new semi-solid-state wireless power banks split into two ultra-thin models starting at 6.7mm and two models with a monitor showing remaining charge and cycle count. Every one of them supports MagSafe and Qi2, is rated for about 2,000 cycles and ships with a 1.5-year warranty. They arrive in late August at expected street prices from about 9,680 yen to 12,180 yen. For buyers who value safety and longevity over the lowest sticker price, they look like a strong option.
