This inverter worked right out of the box, but stopped working within about a month. Hard to say exactly when, as I was not using this on regular basis and you only know it is not working when the auxiliary battery gets low. Somewhere about 1-2 months in, a voltage sensor I have installed on my auxiliary battery was blinking red, meaning battery was low. The green light on converter was on, so I first thought it was working. I disconnected and reconnected it, but no luck. It is not putting out any voltage. It said it was an open box, but probably a remanufactured item. The price was 30% less than "retail", but since it broke, I guess that wasn't such a good deal. And the return period was only 2 weeks. Not enough time to put any use on it.

I installed this on a Ford E-150 van with a 135 amp alternator. I use it to charge a 100 AH LiFePO4 battery pack. It's rating of 18 amps is misleading a bit, I have seen it put out 22 amps continuously at times. Now even with that massive heatsink, I chose to add a fan to mine. My fist test before mounting it was run for about 45 minutes on a cool day. No fan and the heat sink got very hot, I installed a simple CPU fan dead center over the heat sink and it sucked the heat off quickly. When I mounted it on the wall of the van I put a set of two mini fans that blow down the heat sink. It has yet to even warm up now while pushing the max. The voltage output adjustment is extremely accurate and easy to set.

Purchased this Orion-Tr 12/12-18A (220W) Isolated DC-DC Converter to use in my SUV to charge 2nd battery - a 12.8V LiFePO4 50AH. It works after some troubles figuring out the connection and adjustment. The input/output all marked clearly but for the remote switch, there are no +/- signs, nor H/L pin marked. No specific instruction for this model. There are some of instructions for other models said connecting switch and battery plus to the right hand side of the green remote connector. I gave it a try and it works. The output voltage adjustment screw is very loose, managed to adjust to 13.92V. No Bluetooth connection or any other means to connect to this model.

I ordered this item during the COVID-19 pandemic (still on-going) and expected a large delay. There was never a period of uncertainty. Communication is second to none and the 'working from home' policy is a different level as I even received an e-mail at 2330 at night MLPerformance is a fantastic company and I will not hesitate to use them again. You even get a personal message from them in the package, a nice touch. I wish them all the success and support possible during these testing times. Phenomenal.
We all know how important it is to build a good customer base. The secret to success is to remain competitive and offer great service. ML Performance achieve both of those goals.I asked questions about my purchase before hitting buy. I had a reply quickly and great guidance. The email not only gave me the answer I needed but a link to the right product. Saving me time and confusion.The item arrived as described and was well packaged.I cannot wait to pop the part on my car.Great job ML. I will be coming back soon.
Ive made 3 orders with ML performance now, and have been very satisfied every time. Great value, great communication and service, fast delivery. The quality has been great every time too. Also, only a small touch, but a hand written note in my last package to say thanks for the order. How nice is that!! Keep up the good work!
First of all, I would like to say thank you to ML Performance for making this purchase possible. I have to say its a smooth, fast and easy experience! And I would definitely recommend to anyone out there who wants to order BMWparts. 100% trusted & legit seller!!Looking forward for my next purchase from you guys. Keep it up ML Performace!
After having my intakes recently cleaned, I chose ML Performance to purchase the Mishimoto oil catch can. This helps to reduce the build up of carbon deposits within the intake system, helping to maintain engine performance. A must-buy modification for direct injection engines! The quality and fitment was excellent, and delivery was as fast and reliable as ever from these guys! Thank you!
I must say i am thoroughly impressed with how this company does business. I had the wrong item turn up, contacted ML Performance and within 15 minutes they had sorted a replacement item to be sent out the very next day and the return was done via the courier driver. The new item turned up, exactly what was ordered, got it fitted and it looks and performs sweet. I always think anyone can mess up, we're only human afterall, it's how things are dealt with that counts and on that basis alone, i couldn't recommend them enough. Thanks guys and i look forward to buying from you in the future!
Dealing with Marshall and the team was an absolute pleasure. Rarely do you find businesses with such integrity.I purchased four items (some very fragile) and had them delivered to Australia in less than two weeks. Two items were showing very minor defects that I was not completely satisfied with. I contacted ML Performance via email and Marshall went above and beyond to exchange the items at their cost no questions asked. He then took the trouble to follow up and ensure that I was completely satisfied with my overall purchase.Rest assured that you can purchase from ML Performance with complete confidence.My rating.Communication: 5 starsProducts: 5 starsEase of exchange: 5 starsBusiness Ethics: 6 stars
