Great Item

Just got back from a 7 day camping trip with the R.V. We could use our generator during the day, but could not use it at night. Used the Maxoak with my dreamstation and it worked perfectly all night long. Even with the heater on it was still at 65% to 70% charged in the morning. This is a great product and a must have for a boondocker like myself. Thanks Maxoak. Would recommend this to everyone and I have.
