Wi-Fi compatible portable scanner, the MDS-820W. - Brand: Brother - Model Name: MDS-820W - Battery Type: Li-ion - Included: CD, Instruction Manual, Case I bought this intending to use it on-site, but I didn't end up using it as much as I thought I would, and it's been in storage. I probably used it less than 10 times. I'm selling it now that I've left the field and my work has reached a stopping point. This is a limited-time listing. Thank you for your consideration.
