Worked really well as a power supply for my TV in my campervan
Used to have a problem with the TV in my campervan where the fridge or water pump would run and make a lot of noise on the sound channel. Fitted this to run the TV and the noise disappeared completely.

Perfect with the solar inverter
This has fixed the problem with voltage spikes to my solar inverter. Now the voltage is a constant 13.6V and the inverter no longer cuts out when the sun shines brightly on the solar panel. The wires a could be longer and with lugs but overall very pleased.

Survived
Not paying attention coupling to a 40volt battery and got the polarity wrong. Flash bang 5mm of wire vanished. Coupled correctly and to my surprise works perfectly 13.8vdc. You get a fare splash when you connect normally must be a big capacitor inside.

Rubbish
Utter rubbish doesn't do the amps in ad. Don't touch ever!

Useful for using 12v accessories in Tesla Model Y
Apparently the '12v' socket in a Tesla Y deliver 15.5v and caused an issue with our SUP electric pump. Using this enabled us to step down the voltage.

A good product. Works as it should
Good product. Works well and is easy to use.
User
Compact and effective
Only tested at 20 volts so far, but it produced a stable output of 13.8 volts as stated and ran a Shurflo diaphragm pump successfully.
User
very stable under load
The voltage off this device is very stable under heavy load and seems reasonably efficient with adequate heat disipation in an normal environment

Bom conversor dc/dc
Este conversor dc/dc funciona muito bem e parece ser durável.Está em uso já há algum tempo e até agora tudo impecável.

Highly Recommend.
I have bought several of these, (4) to be exact. (2) for 12Vdc & (2) for 13.8Vdc. I bought one of each for spares and the others have been in my Adventure Van for several years. They do a great job at regulating my 14.2Vdc lithium batteries to the 12 & 13.8V that are needed for sensitive electronics such as a fridge & fan which have microprocessors within them and cannot handle slightly higher voltages. My MaxAir fan has an issue where if the voltage is over 12.8 volts, the small circuit board will go bad, due to a design flaw in the MaxAir fan. Using this 12Vdc converter has proven over 2 years to keep my MaxAir fan in check. My fridge will not operate higher than 13.8 without causing the sensitive computer electronics on board from being damaged, so I regulate the voltage with the 13.8V unit. Do not exceed the rated amperage of these units or they will most likely fail. As a rule of thumb, always be under the rated amperage for long life. They do get warm (Not Hot) if they draw close to the rated amperage, so keep them in open air where they can get adequate cooling.

Super Sache
Wird an einem 36V Akku betrieben, funktioniert perfekt.

Excellent régulateur / booster
Excellent régulateur booster de tension.Il rehausse la tension s inférieure a la valeur de régulation....Impeccable réguler la charge de batteries.
