Hey, there is some interesting info here thankx ...
But can anyone help im looking for a 2nd opinion, comments & recommendations if any
Would this voltage regulator iv found on amazon work with the Pi set to 5v obviously, but connected directly to the Raspberry Pi's power input port, without making any mods to the Pi its self???
Only i hear how fussy the Pi is when it comes to powering off-grid
DEOK LM2596 DC 5/12V Voltage Regulator Adjustable Power Buck Converter+LED Voltmeter

IN+: Input Postive
IN-: Input Negative
Out+: Output Postive
Out-: Ouput Negative
A key switch input and output voltage
green light: measuring the output voltage
red light: measuring the input voltage
with terminal and retain the wire bonding wiring point
If remove the P3 jumper cap, the voltmeter shutdown
Lower Power Consumption
The specs look to be ok to me but im no pro il be honest, im still learning
Im a little hesitant to connect direct to the power port il be honest i can't afford to replace the Pi at the moment & in desperate need to power the Pi by batteries/solar soon as possible as i maybe forced homeless very soon ...
I have 6x 2000Ah 3.7v laptop batteries made into a 7.4v 6000Ah pack, & also 2x small scooter 6v 12Ah batteries from Maplins & have had the Pi working off-grid via a cheap in-car 12v to 5v USB regulator recommended from a youtube video but too much consumption needing 12v (both batteries) to just power the in-car regulator to get a 5v output. its a nice fast easy off-grid set up but i would like to power the pi from just one 6v 12ah battery as im charging the other, have the laptop battery pack as a back up or alternative if there is alot of sunshine out to charge both 6v's, the in-car USB regulator doesn't work on 6v but the LM2596 DC 5/12V Voltage Regulator does, and i have two regulators ... does anyone think im all set to go as it is & ok to connect the LM2596 regulator directly to the power port on the Pi without mods???
Oh & would i need a little resistance as:- Output Current: 2A(normal and stable), 3A Max. or would this not be an issue, i can power radio equipment & neon lights from the regulator without resistance, im thinking there might not be need for resistance, help HaHa
Thankx for your time reading people
