DC barrel type?

What is the DC barrel type? Could it be 3.5mm x 1.35 mm?
I want to buy a second charger. I know it should be 12 VDC and at least 2A, but I am not sure on the type of DC barrel. Any advise, please?

My advice is that, since you have a charger that acts on the normal DC input, you have another that can charge the AeroBook through port C.To do this you must buy a Power Delivery charger of at least 40W and a cable, in case it does not come as an accessory with the charger, compatible with Power Delivery.These types of chargers, in addition to being less bulky than the standard, are used to charge other devices for their auxiliary outputs, so you only have to carry a laptop charger and mobile devices.

Thanks for the advice. I thought about the USB port C, but I though I would better leave it free for some future usage. But certainly, if I don’t find other solution, will go for a Power Delivery charger.
