Tips

#1 Looking after your battery

Don't use a damp or wet battery in your tools and avoid using them in extreme temperatures (very hot or very cold). 


#2 Storing your battery

Take your battery out of the tool you have used it in and store it separately in a clean, dry place out of direct sunlight and ideally in some packaging, such as cardboard, to protect it, at a temperature between -10°C and 50°C. Don't forget to keep it out of reach of children.

Older flash drives might not work.
Port labels are too faint to read easily and the PD out port isn't labelled (I suppose they thought it was obvious since it has a fixed cable). The USB ports are speedy except it won't recognize any of my several SanDisk Cruzer Glides. Others flash drives work okay. Works great as an iPhone USB C to TV HDMI converter.

Worth every penny
Size: USB C to Ethernet Adapter
This adapter provides a stable, hardwired connection when Wi-Fi is not fast enough for heavy law school research. It is strictly plug and play, requiring no software installation. The weight is negligible, making it easy to keep in my bag for campus. Given the excellent build quality and consistent functionality without any drop-offs, it offers solid value for money. It’s perfectly versatile for numerous uses (keeps me from having to use like 3 other dongles)

Works brilliantly with Steam Deck!
Size: USB C to Ethernet Adapter, Size: USB C to Ethernet Adapter
I bought this specifically for a Valve Steam Deck. I recently got a gigabit fiber connection and wanted to take full advantage of it when downloading games on the Deck. I took a gamble on this adapter knowing that Linux generally has incredible driver support without much, if any, configuring. I installed it into the Steam Deck's USB-C port, hooked the other end up to my network switch, and the Steam Deck instantly registered a new wired connection. I didn't even have to go into "Desktop Mode" for it; it all worked flawlessly in the "Gaming Mode". I downloaded a 15GB game in about 3 minutes with the Deck maxing out at 880Mbps. The device itself seems well built with a braided cable and gray anodized aluminum enclosures on each end. It's small and compact so it'll fit nicely in the Steam Deck case's little pouch or in that drawer that every house has that's full of cables, adapters, and dongles. It seems as though it's good value for money as well, like every Anker product I've purchased, but time will tell if something goes screwy down the line.
