I added a MeToo. I understand fully that it will decrease the overall battery life, but I frequently use the clipboard in cases where the keyboard is too bulky, such as for holding sheet music in my hand (replacing a folder of paper music) in chorus rehearsals. Most rehearsals are short enough (3 hours with a break) that I don't use all of the clipboard's battery, but when we have a retreat we rehearse for up to 8-10 hours in a day in a room with only a couple of outlets. It would be nice to just plug it into the base when we are on breaks (vary from 15 minutes to an hour) for some charging. Otherwise I'd have to run back to my room during the hour long meal breaks to plug it in and even then it might not be enough without additional recharging during the shorter breaks.
Exactly how inefficient is this? Even if it was only 50% efficient I'd still use it since any charge at all left in the base is of zero use to me in those situations. I'm suspecting that the real figure is closer to 90% efficiency?
The alternatives are to buy a stand and use it with the clipboard turned backwards with the keyboard still attached behind it, but I like the flexibility of holding it in my hand (though the day long rehearsals will probably leaving me wanting a stand anyway even with the frequent breaks). Another alternative is to just fight for access to one of the few wall outlets. I have one of those tiny Outlets-To-Go power strips that I could bring along to ease the congestion.
Neither of those is as flexible as having the option to enable base charging of the clipboard.
