Customer Reviews
Very well thought out By
I purchased the original power box which is great, but i wanted to have a box with more battery storage inside for longer operation and heavier duty cycle (think field day) so I began to plan out my build on what was probably going to house a 60-80ah Bioenno.  Ibwas getting close to ordering the parts for my build (most from Powerwerx) when suddenly Powerwerx releases the Mega Box.  Your timing was perfect for me.  This is such a well thought out box and the USB type C port is a great touch.  I don't believe I could have saved much money building my own to this level.  Fits the 70ah Bioenno perfectly with room to store the AC charger, inline watt meter, and some various USB cables.  It serves as radio station power fit for field day (with solar panels feeding it 10 amps during the day), and with 600 watt Samlex inverter serves as a backup solar generator for power outages, camping, etc.  Great box, I feel lucky to have one!
