Regarding output in watts, rated watts are at maximum rated output voltage (in this case 18V), which is rarely taken full advantage of in the real world. For instance, if you're charging a dead 12V battery the solar panel will "ride" the battery's voltage, effectively delivering 66.6W at 12V, or 2/3 of rated power using Ohm's Law of P (Power in Watts) = I ( Current in Amps) X E (Voltage). Near full charge voltage of 14.5V or so, you'll see about 80W of effective charge power. Some higher end home PV inverters and chargers can harvest the power available between battery volts and panel max output voltage, but most lower cost equipment can't.
This reality is across the board with virtually all solar panels. One has to manage expectations based on the science and not assume that a 100W panel will deliver 100W under all full sunlight conditions. A much more realistic approach is to look at amperage delivered by the panel, as this is fairly flat across all voltages up to 18V, and calculate accordingly. A 100W panel should deliver roughly 6 amps in full sunlight. The load dictates actual effective power delivered, depending on its operating voltage and/or special circuitry for harvesting solar power input.

I designed and installed PWM systems professionally for 20+ years before MPPT was a common thing in smaller standalone systems. In those days 12V charging and load calculations were done in amperage, as the panel watts number was all but useless in a design calculation. Having been out of the industry for a while, I can see that your response is accurate and that it's easier now than ever to extract that extra power with relatively little expense. In short, I stand corrected and thanks for your comment.

Currently i am charging my Bluetti solar battieries with the wall outlet but this may be a good upgrade? thanks

Yes, this would work on the Bluetti as far as I know. I have a single 100w panel for my AC50B and it charges it just fine. As long as the voltage and amperage fall within tolerance, you should have no issues. I use the adapter that came with my Bluetti to go from the panel to the DC input.
