I upgraded my MPPT controller to a Victron Smart Solar MPPT 75/15 with Bluetooth so I could see watts in, watts out, the voltage regulation for charging current etc. this pleased me far more than it should have
So I purchased an Anker Solix C300 DC, 288 watt hours.
It shows me how many watts per connection, has charged 8 items at once, you can charge through 2 USB C connectors at the same time as discharging from the other connections. Has a fancy display, will charge at 85 watts with a cigarette connector to a XT60 connector. Has a light I can control by the app and gives discharge and charge times at the current usage. Seeing what it can do as I can charge it through my trailer wiring I did for my other battery bank, it's the simple things
I'll charge this from my own power bank as when the solar is good it makes more power than I need so won't get seperate solar for it.

From jump leads and a car battery to this, it's all oddly pleasing.
