High Current Cigarette Lighter Connector Test | Voltlog #473

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.

UNI-T UTi260B Best Thermal Camera For The Money? – Voltlog #358

Welcome to a new Voltlog, in this video we’re going to be taking a look at the UNI-T UTI260B professional thermal camera. As you may know I used to own a FLIR ONE iOS thermal camera that I was using with my phone, it was working okay, it had a thermal resolution of x and a picture resolution of because it had the two cameras and it was doing the overlay thing. Well one day I dropped that camera which caused a fault in the lightning connector and unfortunately FLIR does not sell replacements. 

So I started searching for a new camera, I was thinking of getting another FLIR one but then I discovered this UNI-T camera which I believe is a fairly new model and not a lot of people know about it. But let me tell you the specs, thermal camera resolution 256*192px, visible spectrum resolution 640x480px it can mix the two images similar to how FLIR does it, 2.8” TFT LCD, 5000mAh battery which gives a battery life o at least 6hours, temperature range -15C-550C, rugged design with IP65 protection, micro-sd card for data storage, up to 4 points of temperature measurement. This is a massive upgrade for me, over the FLIR ONE I used to have.

Voltlog #246 – What if we install a heatsink on the TPS61088 boost module?

In the previous video where I took a closer look at the TPS61088, I did some measurements of the output noise but I also ran the module up to the maximum specified output power of 12V 2A. It was to be expected that the losses would turn into heat and just the small size of the board would not be enough to dissipate all that heat safely so the boost chip reached a toasty 150 degrees Celsius and inevitably went into thermal protection.

There were two questions that people mainly left in the comments of that video. First people were curious if this module would behave differently if a heatsink was installed and also some people thought about using this module in a fixed configuration, because if you remember there is a chip on this module that will switch the output voltage based on quick charge spec, depending on what the load is requesting through that protocol but people might just want a simple fixed output. To this I would add a third question of my own, what is the real efficiency figure of this module, at the maximum output. 

Voltlog #245 – TPS61088 Boost Module Test (with QC3.0)

The real limitation for this small module to output the claimed 24W for longer periods of time is temperature. There is not enough thermal dissipation happening with this small pcb. Having a bigger pcb with more copper layers would help and it would probably allow this module to output continuously and prevent the TI controller chip from going into thermal overload. Even so I was impressed that running it into thermal protection several times did not do any damage the chip recovered on it’s own each time and no magic smoke escaped during these tests.

So all of this considered, this is probably one of the best dc-dc boost converter modules I got from China so far and I would recommend getting one of these if the specs meet your needs.
