   For example the Jackery 290 claims to have an MPPT controller but monitoring   
   the charging current and voltage doesn't show signs of one, it looks more   
   like a current-limited step-down converter that doesn't hunt for the maximum   
   power point. I don't want to experiment with it until I have a good idea of   
   what it can or can't accept for input. Their phone support site naturally   
   isn't staffed with engineers and I haven't found evidence of user   
   experimentation beyond measuring run times. One snippet was a mention in the   
   FAQ of 200W solar panels being acceptable, without explanation of what it   
   would do with their excess power. Apparently it limits itself to pulling   
   60W.   
      
   I'm measuring my 12VDC freezer's run time on it. So far it's headed for 15   
   hours, more than enough to sleep through.
