Review on 🔌 MEGASOLAR 12V to 12V 5A Female Cigarette Lighter Adapter - Car Charger Socket with 27cm Cable by Therealwesley Shaw

Wanted this for my 12-5 Kalisaya power supply .5 x 2.1 volt outlet. The connector on my Renogy Solar 12V lightbulb fits very well; My PowerWerks 5.5 x 2.1 Powerpole adapter works fine. This thing won't connect. Why do you ask? All other adapters I've seen have an easily expandable 2.1 center pin hole that can be easily expanded if needed. This Megasolar item is fixed and cannot be expanded. Just a cheap way to do things that may or may not work. Before I send this back, it would be nice if Megasolar would kindly respond to this negative review.
