This one is different from the original one I bought a while back. Without load got 4.23v off it, once a 2.2 ohm wow carto from v4l was put on it, it dropped it 4.113. Still some voltage drop, but at least it's not a regulated drop. It did a very good job of staying above 4.0v for the first 45 minutes.
At start- 4.11, 4.10 (9min), 4.08 (18min), 4.07 (27min), 4.05 (36min), 4.02 (45min), 4.0 (54min), 3.94 (63min), 3.91 (72min), 3.88 (81min), 3.84 (90min), 3.81 (99min), 3.76 (108min), 3.75 (117min), 3.75 (126min), 3.75 (135min), 3.74 (144min), 3.74 (153min), 3.74 (162min), 3.73 (171min), 3.72 (180min), 3.72 (189min), 3.72 (198min), 3.71 (207min), 3.71 (216min), 3.71 (225min), 3.71 (234min), 3.71 (243min), 3.7 (252min), 3.7 (261min), 3.68 (270min), 3.68 (279min), 3.66 (288 min), 3.65 (297min), 3.63 (306min), 3.61 (315min), 3.58 (324min), 3.55 (333min). Stopped there to recharge. At that point the vapor produced was no longer satisfying.
As long as you don't mind fat batts, the vgo isn't a bad choice at all.
