YOOTU Technology: The Power Bank for Heating Vests --- Warmth Without Interruption

The " Battery Shortcoming" of Heating Vests --- Solved by This

Think the pain point of heating vests is weak heat? Wrong! 60% of users complain about "warmth shutdown midway" -- ordinary power banks have unstable voltage and small capacity, barely lasting half a day. This H21 dedicated power bank, tailor made for heating vests, keeps you warm all day in -10℃ cold.

Why This Power Bank "lasts Longer"

12V/7.4V Dual-Stable Output；

Ordinary power banks (5V）can't  drive heating vest carbon fiber heating elements, compromising warmth;

H21 12V/7.4V dual-stable output keeps heating vests at 60℃ constant heat --- body temperature rises by 15℃.

20000 mAh Large Capacity: Warm from Morning to Night

Low gear (energy saving mode): 12h continuous power --- ideal for commutes/ outdoor workers;

High gear (strong mode): 8h runtime -- suitable for skiing/ mountaineering.

Smart Temperature Control: Compatible with All Heating Vests

Long-press switch to adjust voltage gears, matching 99% vest models;

Smart chip monitors temperature in real time --- prevents overheating, extends vest life.

Safety & Practicality --- Both " Exceed Standards"

6 Protections: Worry-Free Use

Overcharge protection: Auto shutoff when full -- no fear of overnight charging;

Short circuit protection: Auto power off during line aging/water ingress -prevents leakage;

Temperature protection: Auto insulation in extreme cold --- prevents battery freeze damage.

Dual Design

DC port: Powers heating vests;

USB port: Charges phones/ tablets (22.5W fast charge) -- even in subzero temps, phones stay "fully charged".

Installation & Use: 3 Steps to Use

Step 1: Select Voltage Gear

Long-press the side switch to adjust voltage to match your vest (refer to manual or consult customer service).

Step2: Connect Heated Clothing

Plug the power bank's DC cable into the vest's inner adapter.

Step3: Store in pocket, Start Warming

Put the power bank in inner mesh pocket, press the heating switch -- enjoy all day warmth.

Scenarios Where It's a Cold Resistance Savior

Outdoor Workers: Work all day, warmth never stops. Low gear lasts 12h -- no socket needed during early morning/ late night shifts.

Skiers/ Mountaineers: High gear for heating vests, USB for phones -- no navigation/ photo delays in -20℃ cold.

Commuters: Lightweight(283g）for pockets --- warmth without "power bank burden".

3 Tips to Extend Power Bank Life

Monthly Deep Charge/ Discharge: Charge to full, use to ≤10%, then recharge --- extends battery life; charge every 3 months if unused.

Avoid Extreme Cold/Damp: Don't store in pockets below -20℃ (cold damages batteries); use waterproof bags in rain/snow.

Clean Interfaces: Monthly clean DC/USB ports with cotton swabs --- prevent oxidation.

This winter, don't let " warmth shutdown midway" ruin your comfort. Equip your heating vest with this " battery savior" --- turn frigid days from "torture" to "ease".

This winter: warmth uninterrupted, family at ease!
