Getting stuck without power is not a lot of fun. The good news is there are plenty of power stations you can pick up to keep your devices going in case of a power outage. Take the Anker PowerHouse 767 for instance: it is an app connected portable power station with 4 x AC outlets (2400W), a NEMA TT-30 AC outlet for your RV, and various USB ports.
You can charge this emergency power station with 5 x 200W solar panels in about 2.5 hours. The Anker PowerHouse 767 is Bluetooth enabled, so you can see real-time input and output information, battery health status, and recharge reminders. This suitcase style power station has a footprint of 20.7 x 15.5 x 9.8 in.
