Do you support small-order wholesale?
Yes, we support flexible MOQ both for new capacitors and tested used stock.
Are your used capacitors tested?
All second-hand capacitors will be tested for capacitance, internal resistance and appearance before shipment. We only ship qualified units.
Which countries can you ship to?
We support worldwide shipping, including India, Russia, Southeast Asia and other regions. We can discuss shipping solution according to your destination.
How can I get exact price?
Capacitor price changes with stock quantity. Please contact us by WhatsApp or inquiry form, offer will be sent within 24 hours.
Can you provide technical parameter document?
Yes, we can provide datasheet for corresponding models upon request.
What is the difference between EDLC, supercapacitor and ultracapacitor?
EDLC (Electric Double-Layer Capacitor), supercapacitor and ultracapacitor all refer to the same type of high-capacity energy storage capacitor. EDLC is the technical and academic name, supercapacitor is the most widely used industry term, and ultracapacitor is commonly used by brands like Maxwell. Our catalog includes 2.7V, 3V and 3.8V EDLC supercapacitor cells as well as complete EDLC modules.
What are EDLC supercapacitors used for?
EDLC supercapacitors (ultracapacitors) deliver fast charge and discharge with high power density. They are widely used in solar energy storage systems, UPS backup power, automotive start-stop modules, industrial power equipment, crane energy recovery, smart grid devices and consumer electronics. We offer both brand-new and tested used EDLC stock for wholesale buyers.
