WHY THE PRICE IS JUSTIFIED

This is expensive per Wh, but the premium pays for measurable mass reduction, advanced silicon-carbon chemistry, active balancing, dual thermal sensing and IPX7 construction—not prestige. It is a specialist tool, not a generic luxury bank.

MATERIALS

Cell anodeSilicon-carbon

Raises energy density, enabling 39Wh in only 143g and improving cold-weather behavior.

FrameCarbon-fiber composite

Provides stiffness and impact protection at far lower mass than ordinary housings.

SealingWater-resistant gasket system

Supports an IPX7 rating for wet-weather outdoor use.

CRITERIA

9/10

Usable Capacity

Manufacturer rates 34Wh at standard 5V output and up to 36Wh in Eco mode from a 39Wh pack.

8/10

Output Delivery

22.5W USB-C PD/QC is ideal for phones but not modern laptops.

9/10

Thermal Safety

Active-balancing BMS, dual NTC thermistors and waterproof construction are unusually sophisticated at this mass.

10/10

Cell Quality

Advanced silicon-carbon cells materially improve energy density over conventional graphite designs.

10/10

Portability

143g, 116 × 46.8 × 14.5mm; class-leading energy per gram.

8/10

Recharge Speed

22.5W input is appropriate for 10,000mAh but not class-leading.

9/10

Build Practicality

IPX7, dual USB-C, knock-to-wake and port lighting; display remains coarse.

IDEAL FOR

·Ultralight backpacking
·Trail running
·Wet-weather travel
·Weight-critical EDC

NOT FOR

·Laptop charging
·Budget buyers

DESIGN & ERGONOMICS

Exceptionally thin, rigid and grippy. Knock-to-wake and illuminated ports work well with gloves or in a tent. Minimalist indicators are less informative than a percentage screen.
