How Does a Small Solar Cell Achieve High Amperage?

Click For Summary
SUMMARY

The discussion centers on the high amperage output of a small solar charger, specifically one that achieves ratings between 1000mA to 2000mA despite the solar cell's estimated maximum output of 250mA at 5 volts. Participants suggest that the device likely utilizes supercapacitors to store energy, which can then be discharged rapidly to charge devices at higher amperage. This method allows for efficient energy transfer from the solar cells to the battery, enabling quick charging capabilities.

dear experts

i saw a solar charger the size of an iphone that has high amperage rating of over 1000mA to 2000mA.

Based on the solar cell size i estimate it to produce at most 250mA at around 5 volts.

I like to know how the high amperageis derived.

is it using super capacitors ?
if so , is it charging up the sc and them discharging to battery at high amperage like 1000mA?

Thanks for reading.

best regards
Ramone

It may be slowly charging some cells inside its box. You can quickly charge your phone battery by connecting to these cells.
