This is a New-In-Box HobbyKing HK-010 Wattmeter & Voltage Analyzer that lists at the USA Warehouse for $19.15 + ship; see here: https://www.hobbyking.com/hobbyking/...arehouse_.html
This unit comes with XT60 connectors and for an extra $3.00 I will include an additional pair of XT-60 to Deans adapters as seen in the photos. So, for $20 you get the meter with no shipping, XT60 & Deans adapters AND you get it FAST!
Why wait for HobbyKing slow service?
