I cannot swear to it, but it's more than likely. You need to blow air inside the case if you are going to try operating your charger on a boost setting OEM has set a strict time limit for using. Favor a lee (please read) the Sears Manual. Hate to see a perfectly good antique replicate Mt St Helens on PMS.
There is nothing wrong mechanically with those power supplies, nothing at all. Got news for you - eighty percent of the electronics in your made in USA auto were made by folks who eat rice for breakfast, lunch and dinner. Do an audit of everything in your rig, what DIDN'T come from China (short list).
The Chinese are capable of manufacturing good stuff and they do it quite often. LG, which stands for "Lucky Goldstar" is now considered "good stuff". The MegaWatt is either Meanwell or a damned good clone. Yeah, I now much prefer it over the old standby Harbor Fright 10-amp transformer charger, even at double the price. Anything reliable that allows me to control reality is top drawer in my book.
If it's a question of "Made In USA" ethics, be prepared to paint yourself into a corner availability and price wise. The USA makes the best construction equipment, tools, batteries, generators, and digital control merchandise on the face of the earth. No heavy shirt can compete with a Pendleton, or Woolrich. But when Daiwa came out with a open face spinning reel that ripped the underwear off my made in USA reel, when Honda provided 1-pull start motors in competition to 100 pull start Briggs and Tecumsah boat anchors, it woke me up.
Loyalty as compared to Foolishness are set too close together for my comfort.
If something is better, it's better. But for some, a Budweiser is better than a Heineken. To each his own. I am tickled I can go on eBay and purchase stuff. Beats not having enough money to purchase anything...
