the same seller will sell you an AC to DC adaptor so you can plug your ass into the mains

or just cut off a usb cable and use the 5V from your whatever the fuck usb outlets any kind

>>1070210
I can actually do that? can u post pics or a simple guide?

strips are 12v and guess what, your car is 12v. kind of.
your battery voltage varies a little bit when the alternator is running. try connecting them into the wiring somewhere. when do you want them to come on? al the time? connect via a fuse to the battery. just when the ignition is on? connect to the ignition relay through a fuse. etc. etc. you can buy a 12vdc rated switch and wire it up if you want.

table indoors use a 12v wall wart/ power supply/ regulator. output power (?) is .9w per piece? so current = p/v = 0.9/12 = 0.075A = 75mA per strip, your power supply needs to be at least this and i guess its per strip so for 4 strips your power suply needs a current rating of at least 0.3A (300mA). more that that is ok but its not efficient. voltage must be 12vdc no more no less

dont expect the ones in the car to last.

no they are 12v strips usb is 5v it won't do shit.

>>1070216
what about battery powered? So I can fasten it under the seat and not deal with wires?

>>1070218
sure you can i suppose.
you can get a 12v battery, they are tiny and actually made up of coin cells (hearing aid batteries) i think. or just use aa or aaa or c or d batteries, they are all 1.5v each so you need 8 in series to get to 12v.

wall wart / power supply would really be easiest, most modem/router power supplies in my box are 12vdc, if you have one they would be perfect. should be two wires stuck together, see if one has a white stripe or line down it, connect this one to red and the other one to black. cut with scissors, strip with your teeth or scissors if you are a pussy. twist the cables together then wrap all the conductor (metal) in pvc electrical tape or use wire nuts or terminal block or something to kkep the + and - separate.

are you talking about routing wires through the firewall into the fusebox? you got to slow down here. i am literally retarded

>>1070227
ok. chill out buddy and we will start again.

you said you wanted them under the table. i don't see a lot of tables in cars so i thought this was in a house. in a house use a wall wart (usa) or power supply (uk) rated at exactly 12V and minimum 0.3A.

now, under seats in a car.
you can use:
a) batteries, buy a holder like this https://www.amazon.co.uk/SODIAL-TM-Cells-Battery-Holder/dp/B00DFQRTT6/ref=sr_1_2?ie=UTF8&qid=1476400760&sr=8-2&keywords=12v+aa+battery+holder
red wire to red wire, black wire to black wire. couldn't be simpler. it will stay on as long as the batteries are in there.
b) wire it into your car
your battery in your car can do like hundreds of amps. amps are current and current creates heat. heat causes fire and is why bad wiring causes fires. nothing to do with voltage (unless its a spark but forget that) current == bad so you use fuses so the fuse melts in a controlled manner before the wire melts and starts a fire.
everything electric in your car runs on the battery and everything (hopefully) runs through one of the many fuses in your car fuse box. check your manual.
lots of these wires that carry your car battery voltage go through a fuse and end up in the passenger compartment anyway: power for your radio, electric seats, air con, interior lights etc etc. if you can find some of these wires and you know what you are doing you can tap into them but e.g if you connect it to your interior lights the leds will only come on with your interior lights. if you connect to your radio and the radio only works with the key in the ignition then the leds will only be on with the key in the ignition etc. etc. if you don't know what you are doing then don't worry. something else that is often in passenger compartments is option:
c) connect it to your cigarette lighter hole.
https://www.amazon.co.uk/Cigarette-Lighter-Socket-Connector-Switch/dp/B00A3BJXJU
connect the lights to this thing, it even has a switch on it to turn them on and off.

>>1070246
thank you. with the cigarette option, is there a way to hook up all the 6 strips in parallel ? thanks

>>1070264
yeah sure you just hook them all up in parallel
cigarette lighter is a heater and heaters draw a chunk of current, thats just how they work, you are going to really struggle to draw more current with leds than a cigarette lighter so fill your boots.

Like pic related if it's a 5V and you're using a micro controller.

>>1070203

>12V

You can hook it up to your fuse box in the car. Depending on the amp draw you want to hook it up to a higher amp fuse. Your fuse box probably has unused fuse place holders that you can use.
