Various suitable ranges for use.

Super-capacitators
Electrical Double-Layer Capacitors.
Supercapacitors (EDLCs) completely operate mechanically without chemical reactions like batteries, which provide more than 10 years of operation with at least 500,000 uses without energy decay like batteries.
Spark Proof

Device will auto shut down, Safely jump start engines without the worry of incorrect connections or sparks.

Device will auto shut down to protect against overheating once the internal operation temperature is over 75°C.

Protect against fire and powerful jets of water to ensure the device to be operated in and safely under any circumstances.
Smart design
Auto Detect Ignition System
When the "MODE" button is pressed after the Jump-starter is connected to the battery and fully charged, the Auto Detect Ignition System is activated. Stored energy is automatically released to the vehicle with out outflow when the engine is being started.
Self Control Discharge System
When the vehicle battery is lower than 10V, the autodetect ignition system will be shut down. User needs to use the remote control that comes with the device to discharge the device and jump start the engine manually without energy outflow.
Patent NO.: 7L 2017 10042484X

Our products utilize supercapacitor instead of standard lithium batteries. A supercapacitor is an electrical element with an electrochemical principle. It does not undergo any chemical reactions when it is used and during energy storage. It can repeatedly release energy and charge quickly for thousands of times.
* Device can be recharged within 3 minutes on any 12V battery via the battery clamps/crocodile clips.
1. EXTREME WEATHER (-40°C to 65°C / -104°F to 149°F). Restrictions and other terms apply.
2. Full capacity and function in extreme weather (-40°C to 65°C / -104°F to 149°F).
3. This function is available either the vehicle battery is lower or higher than 10V. Our company Asia Bright Ind. (HK) Co. Ltd. also registered the Auto Detect Ignition System and the Remote Control for the patent, which are technologies originated and exclusive from our company.
4. Device will auto shut down to protect against overheating once the internal operation temperature is over 75°C. Safely jump start engines without the worry of incorrect connections or sparks.
