Inverter vs. Roland BA-330

If you go the AAs route you're likely to go through a lot of batteries. Please take care to dispose of them properly. They do not belong in the garbage.

Absolutely. I put my depleted batteries in piece of Gladware and bring them to my local transfer station where they have a hazardous materials area for batteries. The people there inspect them before accepting them. Incidentally, my local fire department suggests applying a piece of electrical tape to the contacts of depleted 9-volt batteries to reduce the risk of fire.

I’m disappointed by the weight of the Phil Jones Briefcase. 30lbs. is not terrible but I would rather have it be lighter. The Markbass Minimark 150/250W combo has two 6" speakers and weighs 20.72 lbs. 150w @8 ohms; 250w @4 ohms (by adding any 8 ohm cabinet) but it lacks the battery option. The cost is similar to Briefcase Ultimate.

It depends on the use case. If you're trying to run a small tailgate blender rated on 200w then a 300w inverter may not provide enough start up power.
The Ryobi is 300w continuous. It has protection circuits that kick in if you overload it, or overheat it.
In this case with amplifiers with SMPS they have soft starts anyhow.

Batteries will wear out over charging cycles, many of the inverters with built in batteries can be harder and expensive to change. Clip in batteries that can be replaced and spares carried are good. 3 year battery warranty, and 5 year on the inverter. It's hard to find those kind of warranties.

It's not 100% duty cycle because of the battery and how batteries behave as these are discharged. Ryobi is using this to color their marketing glossy.
