Portable CO Detector Support 500 Hours Standby: LSENLTY portable carbon monoxide detector’s standby time can last up to 500 hours. When the detector is plugged in, the device’s screen backlight will remain on. When the detector is not plugged in, the device will automatically turn off the screen backlight without any operation after 5 minutes. The CO detector continues working and monitoring the carbon monoxide concentration. You can short-press the power button to turn on the backlight.
More Accurate CO Detector: Carbon monoxide is detected by an electrochemical sensor, and the measurement range of carbon monoxide is 0-1000PPM, accuracy is ±5PPM. The temperature and humidity use an imported Swiss sensor and support a quick refresh of 2 seconds. The temperature measurement range is 5℉ ~ 122℉, the accuracy is ±2.7℉, the Humidity measurement range is 0 ~ 99%, and the accuracy is ±5%.
Convenient Design: Portable and compact design (dimensions: 0.3*6.6*1.4 inches), equipped with a lanyard design. The LCD shows the temp, humidity, and CO concentration values. It supports placing on the desktop or hanging on the wall or bag, etc. Suitable for camping travel car RV etc.
Alarm Function: When the value exceeds 50PPM, an alarm will be issued. As the PPM value increases, the frequency of the alarm will increase. If you need to turn off the alarm sound, you can short-press the button to turn off the alarm sound. But for security design, if the CO concentration continues to exceed 50 PPM, even when turning off the alarm sound, the alarm sound will continue after 15 seconds.
10-Year Sensor Lifespan: Enjoy greater safety and peace of mind thanks to import CO sensor’s 10-year lifespan.

It works. But runs out of battery quickly. (Company Replaced)
I got this for using a heater inside my car when camping. I tested it several ways, and everything on it works, and alerts as promised. Only issue is the battery runs out quickly. You’d hope it would last longer, but I found myself constantly having to recharge it, and thus, for something that is suppose to alarm you, it’s not really that good. UPDATE: a year later. I posted this review about 10 months after purchasing this. Gave it 3 stars. The company reached out to me, and apologized fro the bad battery issue. So they sent me a brand new one for free. The old one had a white case, the new one had an orange one. The new one the batter does work as was promised. Customer service A+.

Do not purchase
I wouldn’t recommend buying this product. Half the screen stops working when it gets to a certain temperature. extremely difficult to read in sunlight. Battery never seems to fully charge. only two bars instead of three after days of trying to charge.

Small, useful safety device
Long battery life and very light weight make this device handy and super portable – can move it around to different areas of the house as needed or take it with you easily, wherever may be useful to monitor CO (e.g., camping, vehicle, etc.). Humidity and temperature are an added bonus. Comes with a sturdy USB cord.

Nice little monitor for camping, Rv’s and enclosed spaces
This handy little device is great for rv’s, camping or any enclosed space. Easy to charge via included usb-a to usb-c. It will operate while being charged and continue to stay on using shore power. Or will run up to 500 hours on battery. now honestly I haven’t tested the 500 hour mark but I can say it lasts a really really long time. 500 hours = 25 days if anyone is curious. Charges fairly quickly too.I have a gas stove so I turned it on with no flame and held this over it, nothing happened even though I could spell the natural gas. So confirmed this cannot detect natural gas or propane as stated. Then after clearing the air with the hood fan, I placed a small piece of paper on a plate and lit it on fire then held this device over it. It took about 4 seconds and then the numbers started shooing up, the alarm started and it was in the red. Put out the flame and cleared the air with the hood fan. Took longer to stop the alarm and read ok levels.So I got curious, is this thing a smoke detector or carbon monoxide as it states. Does burning paper produce CO? Google: “Paper will therefore release a lot of hazardous substances into the air when it is burned. Garbage that is burned not only damages the air quality, but it can also leave chemical traces on the ground. Carbon dioxide (CO2) and carbon monoxide (CO) are released when any type of organic material is burned” Huh! The more ya know!Well with that I can confirm that this little device works! It also tells you the temperature and relative humidity. However, it can only detect 5° F to 122 ° F. While that’s good I would have preferred a better range. Also the temp sensor seams to be about a degree or so off from the actual temp. I checked this against 3 different temp sensors I have and it always reads 1-2 degrees higher than the others. I wonder if it has residual heat from the control board inside causing a little more heat in and around it. This is the reason I took a star off. Other than that it works great and is easy to use and read!

Safety Net
Just what you need to keep you safe when traveling. I travel a lot in my job, and stay at hotels. I’m sure you have heard about travelers that never woke up, due to faulty heat, and air units giving off gas. This handy little device will give me peace of mind. The device is small. It has an easy to read display that shows temp. relative humidity, and CO levels. The chassis seems to be made of metal, and is sturdy. It comes with a lanyard you can attach to a suitcase, or bag. The displays turns off automatically after a few minutes. It can also display Celsius as well.

Seems to work
I bought this just to monitor and test around the house as I have a fireplace and other items I was curious about. It seems to work fine. I can place it at the exhaust of a vehicle and it goes nuts. I place it above the smoldering fire in the fireplace, it goes nuts. It’s nice to have the ability to check and see if something you are using is producing carbon monoxide.
