Hi, first of all I'm not that knowledgeable when it comes to flashlights. Feel free to share your thoughts and questions in the comments. Anyways, here are some of my thoughts on this cheap aliexpress keychain light. I bought 4 of them for 10€ about two years ago. Gave some of them away. They look very much like a rovyvon a8 clone. Don't expect top notch quality but for the price they are good. Here are some pros and cons:
+very affordable
+button is acceptable
+magnet works
+led is acceptable
+6 different modes in side leds
+tiny size
+usb-c charging
-charging cover is bad quality
-keychain is bad quality
-clip is plastic
-quality overall is not as good as more expensive options
-non-replaceable battery
-lacks a real moonlight mode
These are claimed to be manufactured by yiwu candlelight electronic technology. It has got four main modes. Highest output is claimed to be 400 lumen. Next to the Convoy T3 519a 5700k (300 lumens?) it is noticeably dimmer. Battery is 500 mAh. I believe this is accurate. Considering how small this thing is I would say the output (even if not even close to 400 lumens) and battery size is what could be expected. It is shorter than a TS10 and maybe half its thickness (6,4×2,7cm). It just disappears in a pocket.
Double press – on – > single press – change Mode
Triple press – side Led – >single press – change Mode
Long press – off
Memory always on for the main modes
These are the modes on the side-leds: 1. White light 2. Blinkning White light 3. Uv light 4. Red light 5. Blinkning red light 6. Red and blue blinking lights (might avoid this one in public). Honestly, white, red and blinking modes of those would be enough.
Charging port cover is not to be trusted so water-resistance may be a problem. My keychain broke almost immediately so would just remove or replace that. The clip is part of the same piece of plastic as the body. You can actually un-screw the bezel and gain access to the led which the manufacturer claims is Samsung branded. Anybody able to identify the led based on the picture? Forget the keychain and you are left with a very affordable, working, tiny flashlight with a magnet. Great for in a emergency or if you need to carry only one charger and need something tiny. At least mine is still working two years later.
