The flexibility of the Arduino Uno''s power supply options is one of its many advantages. The board can be powered directly via the USB connection from a computer or USB charger. Alternatively, an external power supply can be used—whether it''s through an AC-to-DC adapter, commonly referred to as a "wall-wart," or a portable battery pack.
Not to mention, I don''t have many pedals that have a battery box I can clip out. Most, if not all, of the pedals I use regularly have the battery in the same area as the circuit board. Which means I have to unscrew the back to get to the battery. I also like to use isolated power supplies, like the Voodoo Labs Pedal Power 2. They keep my ...

In replacing the power supply in Figure 1, getting a power supply that delivers over 3.34A by half an amp is still safe. (Keep it to 20% over at most, because the power supply you''re replacing is likely already oversized by 25 – 30%.) Think of electricity as a hose. The flow coming out is current, and the voltage is the available pressure.
It would only have to have enough charge to power the phone for a minute or two to do the job right. This would let old phones be useful forever. A few external contacts to allow us to power the phone and charge the capacitor through the case would let us power the phone from outside where the supercapacitor would just be a buffer for it.

Yes. External batteries are able to be used with both the Wraith HD 2x and 4x magnification scopes. Doing so will not cause any harm to the unit. For optimal usage, it is recommended to have the external power source charged fully, as the scope will use the external power source, (when plugged in) until it is depleted, then will switch over to the alkaline batteries.
$begingroup$ Generally speaking, battery chargers are meant to charge batteries, and so these may try to detect that there is a valid battery connected before starting to output power, and thus they may perform poorly as power supplies even if you simulate a battery. $endgroup$
Portable Power Supply VS. Power Bank VS. Generator. Sudden incidents like blackouts, disasters, or power cuts can leave your house without power, causing discomfort. While a lack of power energy can bring you to a halt, having a portable power supply, a power bank, or a generator can be significantly helpful.
