In spite of the fact that these clever lights work as advertised, they may permanently damage your USB ports, depending on the design of your own port. The standard USB jack has two pins, which makes it a "real" USB jack. Approximately 15mm thick. PCBs come in these sizes There are two types of LED lights based on basic principles. There are zero grams in each of the 5mm thick sheets. The USB jack on the new MacBook is 35mm thicker than the original. As a result, these lights will apply more force to the pins inside the body of the jack, either bent the pins downward or allowed the springs to break off, preventing them from making contact with normal "real" USB plugs. The other problem is that the leading edge of the light that gets inserted into the USB port isn't shallow enough to move the pins inside the USB jack out of the way as the light slides into the USB As you push the light into the USB socket, the pins can come into contact with the steep edge of the fiberglass, bending downward into the jack. Due to the type of metal used in the pins, bending the pins inside a jack body will result in them breaking if they are not straightened right away. You are left with an unusable USB jack when the metal fatigues and breaks off. There is a possibility that you may break only one pin, or all four In order to use the jack for data transmission, you will need four pins. The only way to bend D+ and D- is by bending If you do not have a USB port, then you are still able to charge devices on that port, but at a lower current (500mA or 250mA, I recommend that those of you who are interested in attempting these should file shallow edges onto both sides of the light, then coat them with a thin coating of superglue to make the edges smoother so that the metal pins will glide over them These modifications are illustrated in detail in the attached pictures. In other words, if your lights are too thick or if the leading edge is too sharp, then you can cause harm to your USB ports. Buyer beware! Either way, it can damage your USB ports in an irreversible way! In case you don't have the skills necessary to replace a broken port, I recommend that you find a USB light that has a "real" USB connector instead of one made from Fiberglass FR4 PCB material that is too thick for this purpose.

A good level of You might want to buy a bunch of these to use with your powerbank if you want a bunch of nightlights. There are some nice ones here. This is a pretty good and bright picture. However, they might be a little brighter if you ran them from a higher voltage source. Using the example below as an example. If you need 25v or 5, you can use either. With a dodgy USB powerbank that has a higher USB voltage specification, you get 5v. . . With an ideal 5v powerbank, you get 9v. . . Voltage drop under load is 0 volts with a zero-volt power supply. At maximum brightness, two of these use close to 260 milliamperes and one uses between 100 and 130 milliamperes. Depending on the voltage specification of the USB port, it could be a little more. I use it for my computer because I have USB ports next to my keyboard right above my computer's keyboard. I can keep my keyboard lit up nicely with it since they have a dimming function (you can dim it some after plugging it in, then brighten it all the way) Additionally, it functions as an excellent nightlight when connected to a USB wall adapter. 3-way USB splitter plug, so I can charge 3 of these simultaneously. )

The only problem is that they fit very snugly into It might be necessary to shave the ends gently with sandpaper to fit in some USB plugs if they are too tight. Do not jam them in forcefully. You might get a lot of heat if you run them all the time on max brightness. The temperature of the room influences the amount of humidity in the air. When I have been using them in a hot room for a really long time, I would tap them to turn them off for a minute before charging their brightness. Although the LEDs should work great, I'm not sure how the RF units will work. I think the soldering is neat, and they seem to be well-made. My cold white ones are always used in my hot climate because I live in one. It brings down the temperature of the room.

Having used these little lights for about three months now, I know how useful they are. The lights are on 24 hours a day. No problems have arisen since I have worked Compared to what I expected, they run much cooler. Despite constant use, all of mine are mildly warmer than room temperature when touched directly on the LEDs after hours or days of use. Dimming works great in this case. You can dim down by touching and holding, and dim up by touching and holding again. Keeping your finger on the button will enable you to power on and off. them in the same room are plenty to see and let you get around if you wake up Essentially these lights can run off of pretty much any source of power (5V, 200mA, 1W) from your battery pack, phone charger, laptop, inverter USB port, etc. These great little devices are easy to use and can provide light from nearly any source. You can insert them in either direction in the USB A port, and they I found this to be a very convenient purchase. I can now install these chargers opposite one another in dual port USB chargers, face up or face down in USB hubs, etc. I'm very.

In fact, they actually remember the brightness setting when you turn them off by using the switch when you use the touch switch to set the brightness. They do not remember the settings if the power to the USB port is lost. As a result, if power is lost, they do not remember how to operate. Power is restored, and the lights turn back on at full brightness after a power outage. Apparently the quality control was poor, because one of the ten lights in the batch was dead (a warm white). I tried it in multiple USB ports, all of which worked with other lights, but was unable to make the failing light work.
