Hopefully that case has the right electronics in to prevent discharging when the panel is outputting less than 5V (which it will most of the time unless in direct sunlight, which is few and far between these days).
Might be worth getting a higher voltage panel (what's the input range of the charger? Or does it just say "USB"?) to account for less than ideal conditions.
Else you might have to get a shotkey diode to prevent discharging, but they're very cheap and very simple to wire in series if you own a soldering iron.
Working on an ultra-minimal control plane for self-hosted / private networks: #WireGuard for all data transport, #Nostr used only for encrypted coordination.
Nostr handles hub discovery, peer enrolment, revocation, and key rotation when a VPS disappears or is rebuilt... no DNS, no fixed endpoints, no single point of failure.
Single pinned authority pubkey, anti-rollback, atomic A/B hub cutover with verification before disengaging the old hub.
Result: private services stay private, access survives VPS failure, and the “control plane” is more resilient than any single (or multi) VPS setup.
On the same quest. Started using a $5/month VPS to act as a proxy for all my home server traffic to protect my public IP, then using Wireguard on top to let me access these services securely from anywhere from my laptop (Proxmox, Alby, BTC Nodes, Jellyfin, developer environments...)
Today's task is to get a regular backup of all my critical data going.
Pictures of monkeys aside I agree and they are useful for proving ownership of physical things that have embedded code such as a vehicle, allowing secure access control.
I visited from the UK last summer and was blown away by the consistency of food quality and the relative good value. Big bowl of ramen for about £5 was standard. Absolutely astounding.
