This is SunJoe model iONBV. 40 Volt, 200 mph, 3 in 1, cordless blower, vaccum, and mulcher
Only used a couple of times as I have another on which is not for sale.
Works with a rechargable battery which has its own charger. This unit works well in a small garden. At full power the battery lasts 20 minutes prior to needing a recharge
