Review: Works well for my solar generator application - Review for MGGi DC Converter 8V-40V to 12V 6A 72W. I'm using this device to provide regulated 12 VDC power from a DIY solar generator to a few electronic devices including an internet modem, a router, a 12 VDC to 19 VDC laptop power adapter, and a couple of small battery chargers that require 12 VDC. The battery voltage on the solar generator can range from 11.0 volts to about 14.7 volts. I didn't want to send this range of voltages directly to these electronic devices, hence the use of this converter. The converter seems to be well made and looks to be of good quality. Note that the two negative (black) leads, one for input and one for output, are tied together inside the unit as shown by an ohm meter reading of 0.0 ohms between these two leads. Therefore, the input circuit and the output circuit are not isolated from each other, and I was able to tie the two negative leads together when wiring this device. I have operated this converter for 7 days 24 hours per day with a load of 1 to 3 amps on it, with input voltages ranging from 14.5 volts to 11.4 volts. During this time, the converter output voltage always read 12.1 or 12.2 volts, regardless of the input voltage applied. Note that the meter that I was reading this voltage from only displays one decimal place, so the output voltage may have only been varying by a few hundredths of a volt. Under a load of 1 to 3 Amps, the unit was just slightly warm to the touch, certainly not hot. I expect that the unit might get quite hot if it were operated at its full 6 amp rating. I mounted this converter on a thin piece of aluminum to act as additional heat sink surface area, but that was probably overkill for my application. I am using this device in the same room as a ham radio. So far I have not noticed it causing any RF interference on the ham radio, although I am not using the output of the converter to power the ham radio since the maximum allowable input voltage of the radio is higher than the unregulated voltages that the solar generator will ever put out. Based on my experience with this unit so far, I am very pleased with it and would certainly buy another one for other projects.
Review: Good for step up. - Worked well, does not work well if you swap the voltage around. I used it to step up the voltage in a spare lithium battery that was 12 volts so it could power my Bluetti which only accepted a minimum of 16 volts. Wired some standard solar MC4 connectors to it but you can use different ones.

## Questions & Answers

**Q: What size fuse should be used with the 480w version? what awg are the wires? thanks.**
A: Hi Dear Customer
We suggest you to use 80A fuse for the 480 Version. Wires input 10AWG, outout 12AWG.
If still any question, please contact us.

**Q: What is the minimum load required for the converters (both 10A and 20A versions) to operate properly?  Also would running without load cause damage?**
A: Dear Sir/Madam,
Thank you for your question.
10A versions long-term working current is about 7A. Limit resistive load.
20A versions long-term working current is about 14A. Limit resistive load.
Running without load will not cause damage.
Hope the answer can help you. If any question.please contact us.thanks.

**Q: Can this be used to charge a 24v cart battery from a 12 car battery**
A: Dear Sir/Madam, 
Thank you for your question. 
Sorry, It can not be. This is for voltage booster, it is not for charging. Please note it.

**Q: For a desired 8a/24V output, what would be the over all power loss (how many input Watts needed for 192W out)?**
A: Hi Dear Customer,
Input voltage range DC 11-16V; output voltage: DC 24V(non-adjustable); output current: 20A(max.); output power 480W.

### ⭐⭐⭐⭐⭐ This reliable 12 volt to 24 volt DC 250 watt converter is silent
*by J***S on March 9, 2025*

This is the second time I have used this 12 volt to 24 volt DC converter to feed my wife's Inogen portable oxygen concentrator will driving in the car. The cigarette lighter output is a convenient source of 12 volts. With 214 volts concentrator battery will charge rapidly while still running the concentrator at full output. At home, a 125 watt AC supply does the job. I used a 250 watt converter to have some headroom because cooling would not be ideal. This unit worked without a fan the first time I used it. The second build for the other car was in an enclosure with a different form factor to fit under the seat in the car. I used a fan for this one, but it probably was not necessary. I reviewed details of this build in the review of the BUD Industries CU-234 Aluminum Econobox.
