Supercapacitor 100F 2.7V — Massive Energy Storage
The 100F 2.7V Supercapacitor stores an enormous amount of energy compared to regular capacitors — enough to power a microcontroller for minutes or even hours after main power is removed. Supercapacitors (also called ultracapacitors) bridge the gap between batteries and capacitors: they charge in seconds, last millions of cycles, and discharge slowly.
Supercapacitor vs Battery vs Regular Capacitor
| Property | Regular capacitor | Supercapacitor (this) | Battery |
|---|---|---|---|
| Capacitance | pF – mF | 1F – 100F+ | N/A (mAh rating) |
| Charge time | Microseconds | Seconds to minutes | Hours |
| Cycle life | Unlimited | 500,000 – 1,000,000+ | 300–500 (LiPo) |
| Energy density | Very low | Low–medium | High |
| Self-discharge | Very low | Higher than batteries | Low |
What you can build
- Backup power: Keep an RTC or MCU alive during brief power outages
- Quick-charge devices: Charge in seconds, run for minutes
- Energy harvesting buffer: Store solar or vibration energy for intermittent use
- Motor start assist: Provide burst current for motor startup
Technical specifications
| Capacitance | 100F |
|---|---|
| Voltage | 2.7V (max) |
| Type | EDLC (Electric Double-Layer Capacitor) |
| Cycle life | 500,000+ charge/discharge cycles |
Frequently Asked Questions
Can I replace a battery with a supercapacitor? For short-duration backup (seconds to minutes), yes. For long-term storage, no — supercapacitors self-discharge faster than batteries.
Can I exceed 2.7V? No. Exceeding the rated voltage will damage or destroy the supercapacitor. For higher voltages, wire two in series (which halves capacitance).
