Multiple power lines
I use a squid outlet when I travel. In cheap lodging there is often barely one accessible power outlet on the wall and I have lots of things to charge, from camera batteries, to a laptop, to more than one phone. That’s just me. With a travel companion there’ll be even more items to charge. A squid splits the power to four flexible outlets. The flexibility gives more room for devices than a simple power strip. This 2-pack Squid is the cheapest, lightest, smallest one I’ve found. — KKaudiobooks
