💡 HUAHA 10pcs USB Mini LED Lights - Keychain Lamp with Smart Touch Electrodeless Dimming Switch for Laptop, Home Decor - Emergency Security Lighting (5 Warm + 5 White) Review

Every once in a while you stumble across an odd little product that you didn't even know existed but you really need and this is one of them from that. Blindingly bright light wherever you need it, on something that fits on a keychain. I use them for lighting model kits and sometimes as a flashlight - just plug into a USB power bank or USB extender from a power bank or charger and you'll get instant light where you need it.

I have used and given away many flashlights of this type (not this brand) in the last 2 years. This brand/batch was a waste of money. 2 didn't work at all, 2 just turned on and off with every touch, some started not glowing evenly like all my other LED sticks. The last pair worked perfectly. I would not recommend them nor would I buy them again. I tried them since they were new to Revain. Now I buy these lamps at eee bayyyy. I'll cover the loss, it's not worth the time and effort to get her…

They impress by actually remembering the setting when you use the touch switch to adjust the brightness when you turn it off with the switch. Unfortunately, without power, they don't remember the settings, and if there is a power failure at the USB port, they forget where they were. They turn back on after power is restored, but at full brightness. Quality control seems poor, there was one dead light (warm white) in a batch of 10 - tried multiple USB ports, they all worked with other lights but

That's great, my backup power can last more than a day. Has proved useful during recent PG&E outages during the fires. They are equipped with 5x soft white and 5x daylight. To be honest I wish they only sold 10x soft white, both work great, but in the event of a power outage, soft white bulbs are less likely to damage your eyes. Especially if it's your only source of light. Either way both are great, very bright and with a USB power bank it lasts all day. They were very useful to me during the…

I bought a similar product from another manufacturer that uses the same set of six LEDs and behaves almost identically. NEARLY. In contrast to others, these special lamps are sensitive to short-term power failures. As a result, they turn off after being on for about 20 seconds when used with some of my phone chargers. Reason: These chargers often emit short bursts of power to detect the load. Other variants of this product performed better under these conditions and survived these brief power…

I mostly use them in cheap USB sockets (which you can buy in most places for a dollar or less each) as night lights around the house. I also take them (and USB plugs) with me when I travel, as I often want the rooms I rent out in other countries to have dimmed lights - two or three of these devices in a room can give the impression of candles. You turn them on by swiping your fingers along the sides, darken or lighten them by holding the end - no moving parts, very cool. I like two different…

This is one of those little things you don't realize until you need it. It plugs into any USB socket on your power bank (and EVERYONE seems to have at least one these days), computer, charger, laptop, outlet, etc. and gives you a massive amount of light. The board has pins on either side so you can wire it to point in the direction it will shine without blinding you. Touch the contact surface on top (where the key fob slot is) and it turns on at full power. Click again and it will turn off. But

I've been using these flashlights for about three months now. They work 24/7 as night lights. I haven't had any problems with them. They work much cooler than expected. After a few hours/days of use, all my LEDs can be touched directly and are just above room temperature. The dimming function works great. Just press and hold to dim, and again to dim. Turn on and off with a tap and release. Three of them in a room are enough to see and move in the middle of the night. These are great little…

I like these. Pretty good and bright. can be a bit brighter if you run them from a higher voltage power supply. eg 5.25V or 5.5V from a dodgy USB power bank with higher USB voltage from a perfect 5.0V power bank with no voltage drop under load. two of them consume about 260 mA at maximum brightness and one of them consumes 100 to 130 mA. maybe a little more, depending on how high the USB voltage is. Power off function Very useful for my computer since my computer sits on my desk with USB ports…

Although these smart lights work as advertised, they will likely permanently disable your USB ports depending on the design of your specific ports. A typical "real" USB connector is 2.15 mm in diameter. These PCB-based LED lights are 2.5mm thick, which is 0.35mm thicker than a "real" USB connector. This means that these bulbs put more force on the pins in the connector housing, potentially either grabbing the edges of the pins and bending them down, or bending the spring of the pins so they…
