Confirm the price and availability with the store. ## At a glance - The listing describes a plug-in receiver and a button that generates power when pressed, with no batteries required. - Offers 60 ringtone options, five volume levels and a flashing light indicator, according to the listing. - The claimed wireless range is up to 400 m/1300 ft. The stated IP65 rating and operating range of -20°C to 50°C are manufacturer claims. ## Pros - The claimed self-powered button avoids routine battery replacement if that description applies to the selected kit. - Five volume levels and a flashing indicator give buyers more than one way to notice a ring. ## Specifications ### Identity - Brand: TECKNET ### Power and battery - Power configuration: Battery Powered ### Dimensions and installation - Dimensions listed: 10.3 x 6.3 x 6 cm; 230 g - Weight listed: 230 g ### Materials and protection - Material listed: ABS ## Before you buy - The listing is inconsistent about power: its title and feature text describe a self-powered, no-battery button, while the technical details say “Battery Powered” and also say no batteries are required. Confirm the selected model's power arrangement before buying. The listed dimensions include a weight, which is also given separately, so it is unclear whether the dimensions apply to the receiver, transmitter or complete kit. The 400 m/1300 ft range and IP65 rating are claims, not independently verified performance. ## In the box - 1 Receiver (Included) - 1 Transmitter (Included) - Manual (Included) ## A good fit for - Buyers wanting a wireless doorbell with a plug-in receiver and a button described as self-powered. - Homes where adjustable chime volume and a visual flash are useful. ## Less suited to - Buyers who need a confirmed power configuration before purchase without checking the listing details. - Buyers who require independently verified wireless range or weather-protection performance. ## Customer feedback Aggregate customer ratings lean positive, with most ratings in the five-star category, but the small sample also includes three-star and one-star ratings. Without written feedback, the reasons for either satisfaction or criticism are unknown. These ratings do not resolve the listing's conflicting power information or verify its range and weather-resistance claims. ## Frequently asked questions ### Does the TECKNET HDB01806BK require batteries?
