Portable power supply Graphene supercapacitor 4500F 4.2V lithium ion supercapacitor 2ah 21700 farad battery capacitor PH2.0 outgoing terminal

Capacity:4500F

Pressure resistance:4.2V

Product Specifications

Graphene lithium-ion supercapacitors have the energy density of lithium-ion batteries, and the fast charging and discharging characteristics of graphene supercapacitors can directly replace lithium-ion batteries. They can support instantaneous output of 5A, which is superior to traditional lithium-ion batteries and can meet more demanding application environments PH2.0 outgoing terminal

Precautions for use

1. Check whether the contact parts of the electrical appliances and supercapacitors are clean. If necessary, wipe them clean with a damp cloth, dry them, and then install them in the correct polarity direction

2. Do not short circuit the charging supercapacitor, otherwise it will be damaged and generate heat, causing the supercapacitor to burn.

3. Do not throw the supercapacitor into water or fire

4. Do not attempt to penetrate supercapacitors with sharp tools

5. It is not allowed to exist in high temperature or humidity environments, which will greatly accelerate the aging rate

6. Do not reverse the insertion of the positive and negative poles, as it may cause swelling or rupture;

7. Do not mix with metal objects, and do not tear off the insulation film wrapped on the outside.
