【Universal 7.4V & 5V Compatibility】Engineered with a dedicated 7.4V/3A DC port (fits 3.5 mm & 3.8 mm plugs + 4.0 mm adapter) plus USB-A (5V/3A, 9V/2A, 12V/1.5A) and Type-C PD 18W in/out. Compatible with heated vests, jackets, gloves, heated chairs, and sleeping bags while also charging your phone or tablet. Not for 12V/18V gear. Love the freedom of powering both heated apparel and daily devices without carrying multiple batteries
【Precision LED Display (1–100%)】No vague “four bars.” Our high-accuracy LED meter shows exact percentage (1–100%) plus real-time voltage and current. Press once to cycle between remaining battery, amps, and volts. Auto-wakes when a device is plugged in and sleeps when idle—eliminating the dreaded “sudden shut-off at 50%” issue
【Heat + Charge at the Same Time】Keep your vest warm and your phone alive. The battery can run a 7.4V heated jacket while simultaneously fast-charging your phone or tablet via USB-A or Type-C. No more unplugging heated gear just to top up your phone
【Fast Recharge in Just 2.5 Hours】Tired of waiting overnight? Our pack supports PD 18W input—fully charges from 0–100% in about 2h 30m with a PD wall charger (≈3h with 15W, ≈4h 15m with 10W). Common battery often take 5–6 hours. Wall charger not included; for best results, use a 5V/3A or 18W PD charger
【Pocket-Sized & Travel-Ready】 At only 3.7 × 2.52 × 0.71 in and 5.9 oz, this matte, scratch-resistant battery slips easily into any coat pocket or handbag. TSA-approved for carry-on, making it a go-to power solution for winter flights, ski trips, or stadium events. How much lighter and more compact it feels
