How to distinguish CDI box with AC fired or CDI box with DC fired?
If headlights turn on without the engine running(with just the key on), it is a DC system. In the AC system, turning headlights on require the engine to be running. Another indication is, if the engine will only runs with a battery it is DC. If it will runs without a battery, it is a AC system.

What does the voltage regulator do?
This regulator has the task of converting the alternating voltage (AC) generated by the alternator into the direct voltage (DC) 12V used in the vehicle electrical system and keeping the voltage within a certain range.
The voltage regulator is also responsible for ensuring that the battery is charged and that the light bulbs do not burn out.

How do I know if the charge regulator can be defective?
- Incandescent lamps burn out all the time.
- Headlights get brighter and darker.
- The battery is constantly empty.

Great for adding USB ports to any USB-C device.
Size: 0.7 ft, Style: USB-C
I needed this to allow for more USB connections on my laptop. It is totally compatible with any USB-C device. I like the small blue LED on it that shows it is powered on. It's very small and lightweight and inconspicuous in design. Love the value for the price.

Great replacement screen for an old Chromebook
Size: 15.6" 1080P
Needed a new Screen for an older touch-screen Samsung Chromebook that bit the dust. Repairing it wasn't an option since it's no longer available. Enter this gem of a portable monitor. It works great. Not a replacement touch screen, but works fine with the chromebook touch pad or mouse and dongle. Easy to hook up, a bit testy on first several attempted to bluetooth connect, but works fine now. The speakers leave a bit to be desired, but I just use Bluetooth speakers anyway. Overall, very pleased with the screen clarity and responsiveness of this portable monitor. 15" screen. Great value! I'd buy it again.

Exceptional - Better than one twice the price
Size: 15.6" 1080P
I bought a different external monitor a few years ago for twice the price and it was abominable compared to this monitor. This monitor is absolutely perfect. The speakers are definitely tinny like others mentioned, so don't expect to DJ a party with this thing, but for work it's perfect since that means voices are clearer anyways. The sound just isn't as full/rounded with proper bass, but it doesn't even matter because there's also a headphone jack on the monitor, too. USB-C is a total game changer for powering and passing full audio-visual in a single port. The included cables are also a big win since getting a spare data USB-C cable can get pricey and I know the one included is guaranteed to work with this monitor. It was literally plug-and-play with my 2023 16" Macbook Pro. I could go on and on about how every detail of this monitor is perfect, like how the stand is also a screen protector cover and how light and easy it is to carry and how the little grippy feet hold it in place confidently, but my point is THIS is FINALLY the external monitor I've been looking for!!!

Great purchase and recommend!
Size: 15.6" 1080P, Size: 15.6" 1080P
What a great product! First I’ll start by saying it’s very lightweight which is what I needed to fit in my bag. I bought two of them because I need three screens and I couldn’t be happier. Set up, one cord!!! No power cord needed pulls power from the laptop so that’s a huge win in my book! I love the size I love the case is attached. Definitely recommend

Works as advertised, but included USB-C cable was defective.
Size: 15.6" 1080P
This monitor performs great! Picture quality, brightness, all work as expected. When powered by a phone, you may have to limit the brightness below 80% if you don't attach extra power. The good news is, I can attach a power bank for the extra power, and any extra power not needed by the monitor will pass through and charge my phone. I've tested this with my laptop, phone, and tablet, and it works great in all cases. One extra plus that I didn't expect, because it was not listed in the product description and also not mentioned in any reviews that I saw, is that this monitor has VESA compatible holes for a VESA mount hidden behind the magnetic cover on the back. Beautiful. If I ever decide to mount it to an arm I can do it. All the advertised functionality works as expected with ONE exception. The USB-C cable that came with this monitor was faulty. It had a short across a couple of wires which could have caused damage to my phone had my phone not recognized it and alerted me of foreign object or water in the port. That water and foreign object warning basically means something is causing wires to be connected that shouldn't be and assumes you have a good cable. In my case, it was the cable itself that was faulty, and I used a tester to make sure. While the description says "do not use other USB-C to USB-C cables", that is just to cover themselves, because many people will use a USB-C cable meant only for charging, or one that is not display compatible. I have cables of varying lengths that are Thunderbolt USB-C which all handle between 100-240W power, data up to 100Gbps, and displays up to 8K. I just used one of my cables and everything works just fine. If you're having trouble with your monitor, or intermittent connections with the monitor (I did before I got the warning) then you may have a bad cable. Get a quality cable and make sure it's rated for display port, high data throughput (ideally minimum 40Gbps), and decent power capacity. Some will work for data but not power. Some work with power but not data. Some work with power and data, but only one at a time. You have to flip the connector to go between modes. I don't know why they make those, and those that manufacture such garbage should be locked up, but that's another story for another day. Bottom line is this. It's a quality monitor. If it ever starts having issues, I'll update the review. The cables I'm not so sure of. The HDMI cable is sufficient enough for FHD display, but I wouldn't recommend swapping it over to a higher res monitor, as it probably can't handle it. The USB-C cable has quality control issues, as they sourced out inexpensive cables for this monitor to keep the costs down. No big deal for me, as I have an abundance of good cables, but keep that in mind that you may need to consider the cost of quality cables for this monitor. I'm glad I bought it. It's going to make me much more productive. While I was disappointed in the USB-C cable, it's not a deal breaker as I already had plenty. Minus one star for the bad cable.
