Can you power a smartphone (no battery at all) by a power supply
$begingroup$ I modified an old smartphone (Oppo Find 5) to work directly from a USB power supply by connecting the battery contacts to 5 V directly or via a diode to lower the voltage slightly. That works for that model phone. There is no guarantee that this will work for other phones as well! In the end, you will just have to try what works. Some phones need a lot
is it stupid if someone''s saying that he/she doesn''t need phantom power
For example, I have an old Shure Beta Green 4.0 that can run off phantom or an internal AA battery. Tube microphones like the Telefunken U47 or the Sony C800 need additional voltage and require an external power supply. And wireless lavaliere mics include a battery pack that both powers the transmitter and supplies voltage to the mic.

6 FAQs about [Battery requires external power supply]
What is an external power supply?
An external power supply is simply a separate physical enclosure or device that can charge a laptop. It connects to your PC through removable or hard-wired electrical connection, cord, cable, or other wiring, while some models also allow wireless charging. However, an external power supply isn’t just important for charging PCs.
Should I buy an external power supply?
Before buying an external power supply, ask for the battery life estimate. Chances are you will connect multiple devices, including laptops, smartphones, and cameras to your external power supply. Further, you may be someone who uses their laptop for demanding tasks such as gaming and streaming TV shows.
Are there external battery banks for laptops?
There are external battery banks which can output voltages acceptable to many laptops. They are chunky, hard to find and often from vendors who grossly overstate their capacity.
How much power do you need to charge a laptop?
When shopping around for an external power supply for a laptop, look for one with a voltage output of 60 Watts or more. That's enough dc power to charge most 13-inch notebooks. But if you're looking to charge a bigger laptop with a 15-inch display (or larger), go for a battery pack with an output voltage of 85 Watts and above.
Can a laptop battery be charged outside?
No. Laptop batteries connect inside to a charging circuit (the the AC adapter uses). This does not connect to the outside case and outside cannot readily get to the charging circuit.
Is it possible to put a battery port on a laptop?
It would seem to me (though I clearly don't know much about these things), that it should theoretically be possible to put a port on laptops connecting directly to the charging circuit to which you could attach generic batteries that wouldn't have to be tailor-made for the thousands of laptop models out there.
