00:00If you've ever had a project stall out because you were missing the right power supply, this one's for you.
00:05I went digging through hundreds of listings, checked the ratings, checked the sales numbers,
00:10and pulled together the 5 best DC power supply adapters you can actually get for cheap right now.
00:15Some of these are under 3 bucks.
00:18Let's get into it.
00:20Starting off with the one that honestly surprised me the most,
00:23this is a switching power supply that comes in basically every voltage you could want.
00:283 volts, 5, 9, 12, 15, 18, 24, all the way up to 36.
00:34And the current options go from 1 amp right up to 50 amps, which is wild.
00:39It takes standard 220 AC and gives you clean DC out the other side.
00:44What gets me is the price, $2.78.
00:48That's it.
00:50Nearly 5,000 sold, sitting at a 4.9 rating.
00:54If you're building anything from a small Arduino rig to a big LED setup,
00:58just grab a couple of these and keep them in the drawer.
01:01Next up is a similar idea but aimed more at the benchwork crowd.
01:06This one covers 5, 6, 8, 9, 10, 12, 13, and 15 volts, with 1, 2, or 3 amp options.
01:14It's basically a lab-style adapter, so if you're prototyping and you need to test a circuit at a few
01:19different voltages, this is the flexible option.
01:23$3.85
01:25Also a 4.9 rating with just under 5,000 units sold, so people clearly aren't having problems with it.
01:32Great little workhorse for the price of a coffee.
01:35Third one is built specifically with LED strips in mind, and you can tell.
01:40It runs off universal input, 100 to 240 volts, so it doesn't matter where in the world you are,
01:46it'll work.
01:47Output options run from 5 volts up to 36, and the amperage goes all the way to 30 amps
01:52for those long strip runs that need real current.
01:56$5.76
01:57If you've ever had LED strips dim out toward the far end,
02:01it's almost always the power supply, not the strip.
02:04This fixes that.
02:06Fourth is the plug-and-play option.
02:09This is the classic wall adapter, universal 100 to 240-volt input, 12 volts 2 amps out,
02:15and it ships with EU or US plug options.
02:18No wiring, no terminals, no screwdriver.
02:21You plug it in and it works.
02:24People are using these for security cameras, DVRs, NVRs, LED lights, small robots, all sorts.
02:31$5.33, 4.7 rating, and over 4,000 sold.
02:36If you just want something safe and finished-looking instead of a bare board, this is the one to get.
02:42And last but definitely not least, the adjustable one.
02:46This covers 3, 5, 9, 12, 24, and 36 volts with current from 1 amp up to 10,
02:52and the adjustability means you're not locked into a single voltage.
02:56That's genuinely useful when you're testing a motor or a module and you don't know exactly what it wants yet.
03:02$7.14 makes it the priciest on this list, but it's still the cheapest adjustable supply I've come across.
03:09Over 4,000 sold at a 4.7.
03:13Worth having one on the bench.
03:15All 5 links are down in the description, so go check current prices because these do move around.
