Review: Excellent product and service - As described, note that it needs to have a constant 12v supply as the battery charge is not very long. Seems to be a quality product
Review: Be careful - it needs to be plugged in to power! - Tbf if you read the description carefully you will spot this, but I didn't. This needs to be permanently plugged in to 12 volt usb. The "battery" is just an emergency back up and lasts a couple of hours. I thought it would work on battery the whole time so useless on my boat.

## Questions & Answers

**Q: How do I switch it on without a power supply?**
A: Dear customer



There is a switch on the back of the product. You need to turn on the switch when fully charged, and the alarm will enter the working state.

**Q: Would this detect R290 Refrigerant Gas?**
A: You need to look at the gas flammability limits for R290 which are: lower limit of 2.1% by vol & higher limit of 9.5%
by vol.
This device is set for detecting limits of lower limit of 5% & higher limit of 15% by vol, so this device will not be suitable, look foe a device that detects Propane.

**Q: Purchased this detector for small campervan - but  instructions (inside box) says 'Not suitable for boats  caravans where different standards apply ?**
A: I use one (alongside carbon monoxide detectors) and keep it permanently plugged in as it draws very little electricity. I can’t remember without seeing the full instructions but I believe it means it’s not suitable as your whole defence. It will detect gas (make sure you place it appropriately and as per instructions as some gases rise and others stay lower) and go off but get two, always keep ventilated and you’ll be much safer than you were. Contact them directly for more specific guidance.

**Q: Does this detect propane**
A: It says it can in description - "【Combustible Gas Detection】- The gas detector is mainly used to detect natural gas(Main Components: Methane), liquefied gas(Main Components: Butane, Propane), and urban coal gas(Alkane, Olefin, Arene)."
