Plus on occasion
1-4 backup Battery sticks / bars
1-2 sets of Bluetooth headphones
The desktop and my laptop are plugged in all the time, so I don’t know if that counts. However my wife has an ipad, iphone and I have an iphone which all get charged overnight so I guess it would be 3 or 5 depending on perspective.
My room is a computer museum, and most of the computers are laptops so by virtue of being plugged in to AC power, they’re being charged. Hmm, technically that’s not true of the WallStreet, I guess, since the expansion bay that typically holds a battery doesn’t, in this case, because instead i have a second internal hard drive sitting there. So… the two G4 PowerBooks, the other WallStreet, and three MacBook Pros of differing vintages. A cell phone also. That’s seven.
Mrs. Charming and Rested bought a plug in outlet adapter that has four USB plugs and six ordinary outlets. We set up a little charging station on our counter and it almost always has six items plugged into it (iPads, Kindles, phones, lighted dog collar, rechargeable lanterns for dog walking, wireless camera monitor. Occasionally, some of those are joined by a GPS receiver, emergency radio, backup battery packs, or camera batteries too. That doesn’t include four laptops (two each for work and personal use) at least two of which are almost always plugged in somewhere else.
I have a 4-USB charger & a 2-USB charger, as well as a bunch of single ones. Certain things, like camera batteries have their own dedicated chargers. I have 9 action cams & have used them all at the same time (& needed to charge them all again) so my answer would be limited by # of available plugs in the hotel room.
Yesterday, at home (& therefore not in a hurry), I consecutively charged:
2 phones
5 lights
1 watch
1 BT headphones
2 camera batteries
3 drone batteries
laptop was plugged in while working
While that was more lights than normal, that can be a typical recharge list.
