It's exactly what I needed: a bike camera, a headlight, and a bike horn all in one. Features type-c charging, the charging is fast and battery life is good. I'm really happy with it!

I like this camera - it's lightweight and comes with battery packs, charging cords, and an SD card. It also comes with a cute bag and strap. The camera quality is not bad! The price is also very affordable!

For shooting video and still photography in remote locations I need to use equipment and power sources which are of sufficient quality and operate reliably. This K&F Concept V Mount Battery is sufficiently versatile for a wide range of power applications and in my experience it performs very well.

It is supplied with an instruction booklet and is compatible with both mini and regular V battery plates enabling it to attach to a compatible camera or V plate used with a videography rig. It can also be used much like a regular power bank for charging phones and other devices. The outer casing of the battery is a carbon fibre effect. It has the standard V batt BP terminals plus two D-Tap in/out, USB-A out, and one USB-C in/out.

I especially like the presence of the OLED display which clearly shows charging status and information relating to the power outlets while the battery is in use. Voltage output and remaining usage time are present in the display based upon amount of power being used by connected devices. It has support for multiple charging protocols including PD, QC, SCP, PPS, and APPLE-2.4A.

It can be charged with a suitable power source using the USB-C input or by my preferred method using a dedicated D-Tap charging unit. It certainly packs a lot of power into a relatively compact battery which is capable of 99Wh, operating at 14.8V.

I have been using it to power field monitors, audio recorders, COB lighting as well as charging a range of portable devices. In summary this is in my opinion a very good quality Mini V battery which is reasonably priced when taking into account the very useful display, capacity and wide compatibility. Over the last few weeks since it arrived It has performed flawlessly and I am confident to recommend.

I figured I was just going to get a camera, a battery, charging cable, and memory card but it came with an extra battery, external battery charger, neck lanyard, wrist lanyard, and protective pouch. The only thing I have a complaint about is that it isn’t USB-A or USB-C. But as for it’s job as a camera, I think it does the job

The camera comes with two batteries, a charging cradle and a charging USB cable that can be used either to the battery in the camera or on the cradle. It also comes with a 32GB micro SD card and a mini SD card adapter. The batteries were good to go.

It was easy to set up and quite intuitive to use. It's very light and feels and looks cheap but takes decent photos. It can take videos too. Stabilization is fair.

It can be used as a webcam with a computer simply by long pressing the power and m (mode) buttons.

After charging the battery it works flawless and has a great image, the video cable is stiff enough to work it around corners. Delivery came as predicted by seller.

This is better made than the other two solar panel brands I own - Big Blue and Solorage.
When charging in high temperatures, cover your device (phone, tablet, power bank, drone battery, whatever) in insulating material like a heavy-duty mailing envelope (cardboard works better than cloth). I've had my devices stop charging at midday with three different solar panel brands - and guess where I live? Florida. At first I suspected the solar panels going bad, and since they're inexpensive enough, I'd buy a different brand. Eventually, though, a notice popped up on my phone - "Charging will continue when the device cools down."
Insulate your device when charging in high temperatures.
Another problem is what I call "backcharge." It's the gradual draining of your device's battery while connected to the solar charger when there's no sunlight. So keep an eye on whether the panels are still in the sunlight or not - which isn't as easy as you might think due to distractions by other things.

This carbon monoxide detector is great because of its portability. It is the size of a hockey puck. I like that it is small and I can take it anywhere. It is rechargeable so no tossing away batteries. The screen is nice, clear and very easy to read. I really like the cute emoji status indicator. The temperature and humidity readings are pretty accurate i compared them to my weather station monitor. I have placed this detector in each of my rooms in my house for a few days to test for carbon monoxide and none was found. It is currently in my kitchen. My wife cooks a lot and this device will go off if she forgets to turn on the hood range fans. The battery life is very good. One charge lasted over a week. One thing I did not like about this detector is the round design. It does look nice, but the kick stand does a bad job of keeping the detector upright. When charging the battery the charging cable tilts the detector either to the left or right.
