Raspberry Pie power

[iPat16]

Hello! I would need to know if it's possible to power up a Raspberry Pie 3 with a rechargeable battery AND a power supply at the same time?

The purpose of this application is that I would need my Raspberry Pie to keep running even if the electricity runs out. With that said, would the Pie shut down if the electricity runs out even if I have a battery attached to it?

Thanks a lot for your help!

This would be the rechargeable battery that I would use : https://www.buyapi.ca/product/lithium-i ... v-6600mah/

Yes and no. You don't power both, but have the battery on standby and switch over when mains drops.

The Pi is powered at USB voltage (5.25v, recommended 2.4A) therefore the cheapest option is one of those portable USB battery packs used for charging tablets and cellphones. The caveat you need to fine one that doesn't cut it's output power when the mains cuts off and switches to battery. The Pi would have no way to tell if it's running on battery so it will continue running until battery is exhausted.

Another option is a UPS specifically made to interface with a Pi or other kin.

USB voltage is 5V, +/- 0.25V. So 5.25V is the top limit -- not a good design point, in case the tolerances pull the voltage high. The "official" supply is 5.1V.

Perfect, thank you for your help!
