4kw heater Phenomenal little heater. Better than espar, webasto, etc. highly recommend. Operation is simple and easy. Dropping the gas tank is tricky, and removing the fuel pump apparatus is also a bit of work. But it’s worth knowing this thing won’t crap out mid-winter. Highly recommended. Was able to fit this under the passenger seat of a 2023 transit, and I was able to rotate the inverter so inverter also fits

Haven't had a chance to test it out… Haven't had a chance to test it out really good. So far gets cold and blows really well! Easy installation. Very nice air con.

NOTE WELL the return policy!! The builder's opinion is that the unit is too heavy for the roof of my particular van. That is not Velit's fault. What I did not expect was the only return within 30 days if it does not work return policy. I did not even think to check the policy because...well, who doesn't have a 30 day return policy for an unopened box? I take responsibility for not checking, but I find this policy completely unreasonable. Now I have a $1700 (including shipping) unit that I cannot use.

Purchased the 12V A/C and 12V gas… Purchased the 12V A/C and 12V gas heater. Had some questions before I ordered and they were very helpful answering all my questions. Will be installing on a 2023 Transit Trail soon. Order came very quick and the packaging for the A/C is amazing, I think a dump truck could drive over it and wouldn't damage it. Great job, can't wait to see how they perform :)

Efficient AC The Velit AC works very efficiently to cool our Sprinter van. It has the right balance of power (8000 BTU) and efficiency for us to be able to have AC off-the-grid while we sleep and replenish the batteries via solar panels the next day.
