tablet + wired network + recharging

Question

Can any tablet simultaneously recharge and use a non-wireless network?

The goal is like an always-on kiosk-like touchscreen, in a location that forbids wifi. Ethernet (not Internet) would be e.g. 192.168.10.xxx to a file server. Static IPv4, not DHCP.

The challenge is that (micro-)USB to ethernet adapters, such as those made by Apple and others, tend to use the the same USB port as a recharger. I'm not afraid to solder fine-pitch connectors into a custom adapter, but I do have distaste for Qi-compatible wireless chargers.

Answer 1

Yes, it is possible, even if it's more difficult that simply "soldering" two pins (which will burn either the tablet, the charger, or both, unless protection kicks in). Due to this difficulty, "dual mode" adapters are rare, and not all models can be supported -- but some do exist.

This is one model by Lava for Galaxy Tab 2; they have also different models.
