In the quest for reliable power accessories, Voltlog embarked on a comprehensive testing journey to evaluate the performance of various cigarette lighter connectors. These unassuming components play a pivotal role in powering our on-the-go devices, but cheap options from online marketplaces often fall short of their advertised current ratings, posing potential safety risks.
The lineup consisted of five connectors, ranging from budget-friendly AliExpress offerings to reputable brands from distributors like Digikey. Through a series of rigorous tests, each connector was subjected to its claimed current rating, with temperatures meticulously monitored using a thermal camera.
The results were eye-opening. Connectors rated for 10A and 15A from AliExpress quickly succumbed to the heat, emitting foul odors and melting within minutes. Even the Digikey connector, boasting a 20A rating and a datasheet, struggled to maintain safe temperatures, with internal components soldering themselves together due to the excessive heat.
Surprisingly, an unassuming AliExpress connector, rated for 20A, emerged as the unexpected winner. Its robust construction and thick middle pin seemed to dissipate heat more effectively, outperforming its pricier counterparts. However, the true lesson learned was that for continuous usage at high currents, a heavy-duty female socket with ample heatsinking capabilities is essential.
Voltlog discovered sockets designed specifically for this purpose, featuring ceramic bases, double metal shells, and extended lengths to maximize heat dissipation. This comprehensive testing underscores the importance of scrutinizing advertised specifications and prioritizing safety when it comes to electrical components, especially those handling high currents.
Voltlog’s dedication to uncovering the truth behind these unassuming accessories is a valuable contribution to the DIY electronics community.
