@@darthvader5634 You can pack it in either your checked bag or carry-on bag. If you choose to pack it in your carry-on you will need to remove it and place it in a bin when going through security unless otherwise told by the TSA.
TIp: to ensure that your laptop is safe during security checks, remember when you put it in a separate bin to send it last. If you send it through the scanner first while you’re still waiting, someone might be able to take it and leave before you go through security. So, be careful and keep an eye on your stuff!
So....other than the laptop, its cords and the power bank....other things can be split apart and stuffed into your carry on...like plug adapters, a travel scale or luggage scale, an immersion heater and backup drives, like a small Sandisk or jump drive? Is that correct? Because putting all that stuff in a bulky electronics bag is really a space issue! Would that be OK if coming back from an airport like Rome FCO and their screening? I can't seem to get an answer even when I search official sites....
You just need to remove the laptop and the power bank. Cords, plug adapters, luggage scale, immersion heater, backup drives and Sandisks can stay in your bag even when coming back from Rome.
As long as they are all for personal use there are no restrictions. Now, if you showed up with a suitcase full of electronics then that would cause some problems but with what you listed you will have no issues.
You have to carry the power banks in your hand luggage but make sure they are under 100 watt hours. Laptops and solar panels can go in checked luggage.
