What kind of gadget do you need while you camping?

well, that depends, what type of camping are you planning on doing, and what sort of area?
whether you tent camp, as i suspect from your avatar image, or RV camp, i would basically recommend a first-aid kit, and some basic survival gear, just in case (we hope it never needs to be used).
the last time i tent camped (i was 15yrs at the time), i made sure i had a first-aid kit, compass, maps of the area, plenty of food and water, plus a method to purify water (used liquid iodine drops at the time). i would recommend at least a set or two of extra clothing, in case you get caught in the rain. speaking of rain, my pack had a plastic liner, but i think people just use dry-sacks now, to protect clothing, bedding, ect.
i can't remember all i took as it was quite some time ago.
as i have a packable camp stove, i like to take Knorr pasta and rice meals. example like below:
they are dehydrated meals that you add water, and sometimes some milk to, and cook. for milk, i take powdered milk, and add water. good enough for camping milk.
there may be something similar in your area.

the list can get quite large, but it depends on where you camp, for how long, and how close to the civilized world you are.
hope this is of some help for you. at least it may give you some ideas.

i really gotta get back into tent camping, i miss it.

EDIT: Knorr pasta sides are a lot cheaper at my local store, than on Amazon

I always bring solar panels and OMEALS. Shop - OMEALS

I prefer electricity in the tent while camping at primitive sites; for tent lighting and tunes as well as the bug zapper used to clear the tiny vampires out of the tent before bed.

...The post beside the chair is for the, collapsible, floor lamp.... a bit much? ..perhaps.

...its more than a single gadget; but accessorization is fun!
& comfort is the goal!

Enjoy!

Now you have.
...Here is an old pic of the, now dead, 35 AH lead acid battery with inverter (under the left end table) ... ((the white wire goes to the ceiling light)).
been camping with electricity and electric tent lighting & stereo etc. at primitive sites for a very long time now (since the 20th century).

LiFePo4 batteries are far superior for this due to their better capacity smaller size and lighter weight, IMO.

the current 50 AH LiFePo4 battery with inverter (similar in size but lighter than the old 35 AH battery (had to make a harness for it to carry it easily, with one hand)

Edit: I try to enjoy life and be comfortable no mater what circumstances I find myself in... tried the primitive bare bones, less comfortable, camping in my youth; I'm older, but I like to think; I'm a bit smarter now!

Enjoy!

Saw this portable microwave (made by Makita; only available in Japan) article while browsing the news this morning...
it needs a shoulder strap and is likely not yet portable enough for backpackers...
