Is it possible to make Raspberry Pi 5 portable?
December 22, 2023, 17:33
So, I have a Raspberry 5 8gb RAM I am getting in 2 days for Christmas. I was wondering something.(This is a question for people who already own the product by the way.) Is there some way so far that we can make the Raspberry Pi 5 portable? Has anyone done it so far? Is anyone planning on doing it? If so what would I need to buy, gather, or pre-order? Is it even possible? If it’s possible what would be the minimum mAh I would need in a Lithium Ion Battery)
i do not have a pi 5 but I can still help
to make it portable you probs just need a screen and a battery
But how would I translate the the power to a consumable power for the RPI5?
how long do you want this to last?
like on regular power usage
I really like these https://thepihut.com/products/2000mah-3-7v-lipo-battery#main , they're small and portable and cheap, you can also get them in 3 sizes which Is nice
<@&818389709134626826> just double checking. if I have two of these together it outputs 7.4v right?
Apparently it usually pulls 1.6A
Unless you heavily use the USB ports
Then 5 Amps
At least 4 hours.
But I have no clue so far wether there is portable UPS hat yet
yeah. but I don't want for you to have to go into low power and worry about instability
So 3A
let me attempt to calculate this
12Ah?
3A draw 12Ah Battery
5A draw 20Ah Battery
Both yield roughly 4 hours of battery time
I'm planning to use 2 of these 2000mah ones which would get you 7 and a half hours with the pi just idle
How many mah does the RPI5 even pull?
so with medium level tasks it would get a little more than 4 hours
No way it’s only 540mah
idle 540, medium about 1000
an idle yes
Oh
I thought minimum it would pull was 3A
nah
pis are very power efficient
Then that confuses me
Why do we have to go from the old 3A PowerSupply to the new 5A Power Supply
because it can use that much
if your really stressing it
plus usb devices and a bit of a safety bonus added on
Oh yeah
do you want this to be small btw?
About the size of those vaults pencil cases
because we need to fit the two lipo batteries and a DC to usb c board along with the screen and ofcourse the pi in this
never seen them
oh
that's doable
do you have a casing to put this in?
because that'd be a problem here
This is a case
I would remove the felt inside and replace it with a non conductive surface inside.
ok cool
I've had trouble with that in the past that's all
that was actually the limiting factor
you want this to be touch screen?
Yes I am planning, when I get the money, to purchase a 1440p capacitive touch screen from Waveshare 5.5”
HDMI
oh you already sorted that?
Yes
ok cool
that makes it simple
I had a display already but I suspect since I left I in its nondescript box it may have been thrown away by a family member
ah ok
now I'm just waiting for them to respond to this. if I'm correct then we can get started
I’m more of a software and simple electronics guy
So I really don’t know how these amperage milli amperage draw pull whatever thingy things work
Last time i tried making a portable pi it was definitely not at ALL considering voltage and amps
Which is probably why it crashed a lot
Im not the best either. I help people around here because It ends up teaching me things. so I learnt about this stuff mostly from a guy I helped create a portable Gameboy
You have helped though more than I understand about volts and amps
yeah np
