TecMate OptiMate DC to DC TM500, 6-stage encapsulated battery-saving 12V/12.8V 2A DC/DC charger and maintenance device

Super Lösung, wenn man das Auto in einer Garage ohne 230v Stromanschluss überwintern lassen möchte. Gibt wenige fertige DC-DC Lösungen und der OptiMate ist mit seinen ca.90€ leider wirklich die günstigste. Funktioniert einwandfrei, nur könnte der Hersteller flexiblere Kabel verwenden, die verbauten werden bei Minusgraden sehr steif.

I use this to trickle charge a 100ah lifepo4 battery from my lighter socket in my van. Works great for keeping the battery topped up between camping trips. No issues so far and really easy to install. Good build quality too.

マンション駐車場ではAC電源が利用できないため、ポタ電からの12Vでバッテリーの補充電に利用中。300Whのポタ電から、A/C出力だと変換効率の点で2日ほどしか持たず実用的ではないが、D/Cであれば10日間ほど補充電を続けられる。

I tow a 2022 Chevy Equinox behind my Class A motorhome. The new cars are all computer driven. The ingination has to been in accesory mode to maintain the steering since it a electronic controlled. You can not safely just run a hot lead from your towing vehicle to the towed vehicle battery without creating a problem. This 12VDC to 12VDC mainainer/caharger will work. I tested it out before hitting the road. I am very happy with it and it works perfectly. I attached it to the engine batteries first and then the vechile. turned the key to acc. and turn on the radoo and interior lites, left hooked up for 8 hours. Battery in car was fully charged when disconnected. I had to buy a add cord to make the length right. Worth the bucks
