Powerwerx MEGAbox Portable Power Box for 30-70Ah Bioenno Batteries

I just received the MEGAbox Portable Power Box.  It is a nice system and works well.  I wish they had included a charging port, and a way to charge the battery with the Powerwerx solar system while the unit is in operation.  Unless I've missed something obvious, you have to open up the box to charge the battery.  This could compromise the system in some field conditions. All that said, Powerwerx is a great outfit.  It is always good to do business with them.

I bought this for astronomy after a review on Cloudynights. Great way to power your setup all night long. Shipping was significantly faster than advertised.

I dont usually submit online reviews, so when I do, a product or service has really tripped my trigger so to speak.  I ordered this MEGAbox along with the Bioenno 40A battery, 10amp charger and Power Meter to run my astronomy gear in the field.  The build quality of this box is top notch using well thought out components.  For example, all of the charge ports have dust covers on them, with particular attention to the covers over the built in Anderson Power Pole ports. These covers are rubber with molded in nibs that insert into the Power Pole to keep dust and moisture off the contacts. Nice!  Another small feature is the cover over the volt meter/USB C port is a smoky grey translucent plastic so you can read the digital battery voltage thru the cover without having to flip it up.  While true, as pointed out by another reviewer, for astronomy use, dim red lights are desirable, but this box meets many needs with many uses.

Customer service these days seems to be a thing of the past, especially with dot coms.  The documentation shipped with the Bioenno battery said to use a 6A charger max. I ordered the 10A.  A call to Bioenno and I got their voice mail, so I called Powerwerx and Dave answered. He assured me that the 10A charger was fine and was disappointed that I had to leave a voice mail at Bioenno.  Hh called Bioenno to verify the charger and promptly called me back confirming it was ok.  Then Bioenno called soon after and also confirmed.  I was blown away with the extent of customer service I received from both companies.
  
I'll definitely be back to Powerwerx as well as Bioenno...they've both earned my business!

I was about to do a box build and then I see this unit.  It has everything (almost) that one would want.  The only thing I might add is an in-line watt/ammeter that goes inline with the battery connection - that way you can monitor the sum total of all the power/current flowing in and out of the multiple connections.  Couple it with one of the high-output Bioenno batteries and you've got perfection.

... for amateur astronomy use maybe the next version could have some red led lights - but don't make them too bright (for example, the Celestron Power Tanks red lights are MUCH too bright even on the "dim" setting to protect night vision).

Other than that, it's perfect !

I plan on a lot of use for it with astronomy, amateur radio field days, and as a backup for home power outages.

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!
