00:00So you've got a 12 volt battery, a car, or maybe a boat, and you need to run something that
00:04only wants 5 volts and you really don't want to fry it.
00:08I've been down this rabbit hole way too many times, and honestly, the little buck converters that actually work well
00:13are all under 5 bucks.
00:15So I went digging, found the 5 best step-down DC converters for 12 volt devices, and here's what's actually
00:21worth your money.
00:23Starting off, we've got this mini DC 6 to 30 volt buck converter board that steps down to 5, 9,
00:29or 12 volts at up to 3 amps.
00:31The thing I love here is the input range, 30 volts down is huge, so this handles car systems, 24
00:37volt setups, solar panels, whatever you throw at it.
00:41It's a bare board, so it's perfect if you're building something into a project box or a dashboard.
00:46At $3.64 it's the cheapest one on this list, it's got a 4.9 rating from nearly 5,000
00:53buyers, and honestly for that price you should just grab two.
00:57Next up is the waterproof 12 volt to 5 volt converter, and this one solves a very specific headache.
01:03If you're mounting something on a motorcycle, a boat, an RV, or anywhere outside, a bare circuit board is going
01:09to die the first time it rains.
01:11This one's fully sealed and comes in a bunch of connector options, USB-A female, Type-C, dual USB, or
01:17just bare wires if you want to solder your own.
01:20It's $5.11, which is the priciest here, but weatherproofing for an extra buck and a half is a no
01:26-brainer.
01:28Third, this 12 or 24 volt to 5 volt car buck converter at 3 amps.
01:33What makes this one stand out is that it's built specifically with cars and trucks in mind, it handles both
01:3812 and 24 volt systems, so it works in a regular car or a semi, and it's CE certified.
01:44You can get it with Type-C, mini USB, or micro USB output, so you pick whatever your device actually
01:50needs instead of hunting for an adapter.
01:54392, 4.9 stars, and it'll charge your phone or run a dashcam without that annoying voltage drop.
02:00Coming in fourth is this one that gives you a choice of 10, 15, or 24 watts, at either 2
02:05or 3 amps.
02:07That flexibility is the whole point, if you're just running an LED strip you don't need 24 watts, but if
02:12you're powering a Raspberry Pi or a small screen, you'll want the headroom.
02:16And the connector options here are the widest of the bunch, mini USB, micro USB, Type-C, male or female.
02:24$4.18.
02:26It's basically a build-your-own adapter, and that's genuinely useful when you're wiring something custom.
02:32And rounding it out, this 15-watt, 12-to-5-volt, 3-amp car converter.
02:38This is the one I'd hand to someone who just wants it to work, 15 watts is the sweet spot
02:42for phones, tablets, GoPros, dashcams, most of what you actually plug into a car.
02:48It comes in male or female USB, mini or micro USB, so it drops right into an existing setup.
02:55It's $479, 4.9 stars, and it's the one I'd keep in the glove box as a spare.
03:01All five links are down in the description, and they're the best prices I could find at the time of
03:06filming.
