I Bought the GooLoo 800A few days ago and compared with the TrekPow G39 I have. GooLoo one is much better.
- Come with car charger, wall charger
- 12v clamp has a boost button to allow higher current output, e.g. drive the 4WD Tyre pump.
- 18000mAh battery capacity compare to TrekPow G39's 9000mAh
- Only LED battery capacity indication compare to 7 segment like the TrekPow
- No Symbolic indication on the 12v clamp.
This one should be a good upgrade to the 800A model. Not sure when is the deal going to expire.
