DC 12V Step Up to 24V Boost Converter 20A 480W DC Voltage Regulator Power Converter Waterproof Module Transformer for Golf Cart Club Car

I use this to speed the recharging of my EcoFlow Wave 2 air condition from my 12vdc camper van solar power system. The Wave 2 power input "auto-switches" "car" or "solar panels" (where current is limited by the panels). The Wave 2 also tops out at 8 amp recharge rate in "car" mode for either 12 or 24 volts, limiting to 96 watts at 12v. However, the Wave 2's auto-switching/sensing algorithm is flaky - it was occasionally popping a 30 amp breaker at 12vdc. This power supply solved two problems.Everything seems much better now at detecting that it's not a solar panel and this power supply puts out a solid 8 amp without excessive heat (it's mounted on a slight dampened/isolated fridge fixture aluminum structure for extra heat sink, though probably not really needed).It has held for many trips, so far taking the vibration well.And, it provides a good 192 watt recharge rate, twice as fast, and no more popping circuit breakers.

These work great! I use the 19v one to charge my notebook in the van, I use a higher current 13.8v one for my Ham radio gear. They will keep the voltage stable, when the batter drops low as it. The expensive 13.8 volt high current ones will keep me transmitting, even when the main battery drops below 11 volts. Some of my radios act up when they drop to 12 volts...

I'm using this along with a 40v powertool battery as an emergency supply for my CPAP machine during the occasional power outage. Voltage is a steady 24.1v no matter if my battery is 42v or 38v. Ripple voltage is only a couple mV, but I'm not sure if that's just induced noise from my lights and stuff. It stays stone cold, but I'm only drawing like 35 watts.

Needed this to convert 12V DC battery supply to power my 19V DC MiniPC to be mounted on my robot build. The MiniPC draws about 3.5 amps and the boost converter is able to handle this with ease. Nice device to keep main battery build to just standard 12V DC.

Many Power Stations require more than 12 volts to charge and won't charge for the car cigarette lighter plug. With this unit you can raise the voltage to a level that will work and charge the station!Now, I don't use it with my car but with a 12.8V lithium battery and it works just fine!

Item is faulty, I thought I was getting it wrong and after months of attempts, I called in an electrician who determined that the item was faulty. Unable to return it since it’s gone 30 days, 22 of which was being shipped to me from Miami to the Cayman Islands. So little consideration given to the time taken by shippers to get to the customer. Unable to contact the sellers so very little can be done.

Works as advertised. Like the quick connects.

I've been using a Wuzhi 200 Watt Bluetooth amp in my truck for about a year now, powered by a DeWalt 20VMAX5AH battery... My dilemma is that this battery only puts out about 18VDC, and the amp card can take 24 or more volts... The more voltage you pump into the card, the louder the output you get out... And I'm a Hard Rocker, so I like it LOUD...So, being the brainstormer that I am, I extracted a 12VDC17AH [motorcycle] battery out of a jump-start box, and ran my wires, as such:POS -> batt>fuse>switch>converter>amp;NEG -> batt>converter IN & OUT>amp...(All soldered & shrink-tubed)All said & done, my multimeter measured 24.6VDC stable at the amp end, from a 12V battery... AND it's 17AH, meaning it'll power the amp card for DAYS before it needs a recharge... I've had to recharge the DeWalt battery every day...The end result is I have almost twice the volume and bass as what the DeWalt battery was giving me, PLUS 4X the capacity... I'M A SERIOUSLY HAPPY GUY... This 12V>24V upconverter works GREAT!!! 6 stars...[In the pic, the two ring terminals go to the battery, and the spades go to the amp]GOOD DAY...UPDATE: I've just bought my 3rd one... That's how good and stable this converter is... Never mind a 24VDC external power supply... 12VDC adapters and batteries are a dime-a-dozen... This converter doubles them up to the 24 volts I need for my cigar box amp builds...6 stars!!!
