Review on Battery Tender 12V Engine Start Assist, Battery Booster & Charger with Mobile Device Monitoring - 022-0227-DL-WH by Lance Foster

Yes, read reviews. WiFi FAIL and short cables. And the cables come out from the bottom of the device. So if you carry this by the handle and then want to put it down, it rips the cords. Dull design. Dumb and Dumber! Press and hold works in that order (but no showstopper); Charge 20A boost trickle charge 12V power supply So if it is connected to the battery in charge mode and I want to switch to trickle mode, does that mean I will put 20 amps into the battery before switching? Bad idea. So we have to disconnect and then reconnect the battery when shifting gears. The list should go from lower power functions to higher power functions. From charging to a trickle, not charging to 20A. And you don't have to hold down the button to select. So much more convenient for the user and the battery. I'm an engineer and thought I was better than others who might have connection issues. No, I couldn't trick bad software. Will NOT connect to a dedicated 2.4G network even after spending time on Deltran calls, changing routers, trying ALL b/g/n options, etc. TOO many hours wasted.
