Hmmm... hopefully it'll take this time. The above blank posts from me was when I tried to send this post the last time.
I LOVE the mic section on the Pa1000! That you have all those controls right up on the board, the fx sound really good, volume and fx amount controls etc., it's way way better than simply a board with a mic in because of those controls.
Anyways, here's what I wrote:
I have a ton of experience with playing outdoors on battery assist.
In the past I used qsc k10 and k8.2 speakers, both of which require A LOT of power. For those speakers I used:
- Deep cycle battery, weighs about 60 pounds, used a 400 watt inverter. The battery, about 70 amp hours?, did well, but doing this setup again I'd use a 600 watt inverter. I would occasionally overload the inverter, which caused it to shut down. I just started everything back up, trying not to play too loudly or with too much bass.
Given you'd probably be playing at a softer volume, you'd probably do just fine with a 400 watt inverter with these speakers.
- I also used a Turbosound IP300 with this setup and found it was roughly equivalent to using the qsc k speakers, which is surprising given how much higher wattage the k speakers are
Before the heavy battery and big speakers, I used a roland cube street ex for years, which did surprisingly well considering it ran off of 8 AA batteries. As a do-it-all amp it did really well- I enjoyed the mic input with reverb, the guitar input with fx and amp modeling, I liked having the 1/8" and 1/4" line ins for keyboards and smartphone.
For $450 and at 18 pounds, it did a reasonable job, esp indoors, but in the noisy drum circles I played with in the park, it just didn't have enough bass oomph and overall volume, which is always the challenge for small, self-powered speakers for keyboards. Though, once again, this may not be a problem for your lower volume use. The qsc K8.2 and esp the K10 was really fun to play for the volume and bass it could produce
I also ran the K8.2 and K10 off of a lithium ion battery with built in inverter. Was really surprised I could pull this off- the inverter was only 300 watts and the battery was only 250 watt hours (wh). Both those numbers are on the low side, and I had even more shutdowns when I played too loudly and or with too much bass. After several months of this kind of grueling use for this underpowered gear, it stopped working well, could only play at low volumes before it would shut off.
Lithium ion batteries are sweet- the one in the above paragraph is only 6 pounds, what a difference from using a lead acid battery! And it was only $130, a low price for 250wh. However, if I was to do the same setup, I would jump from 250wh to at least 350-400wh, and the built in inverter would need to be at least 400-600 watts. You don't want to run equipment like batteries at their limit!
I'm waiting on delivery now for the JBL eon one compact, a $549 unit that:
- has a built-in lithium ion battery good for up to 12 hours light use, 5-6 heavier use
- has BT built in, so you can stream music wirelessly from your smartphone
- 8" woofer and tweeter
- BT mixer, so you can change settings from your smartphone
- 112db sound output, which is much louder than other comparable battery powered speakers
- 4 mixer channels, including 2 mic inputs (1 with phantom power), a high z input for guitar/bass, 2 band eq per mixer channel and 8 band eq on master,
- less than 18 pounds
- has chorus, reverb and delay fx
I've been waiting for a speaker like this for years! Nothing else out there like it. I'll have to see how well everything on it works, and of course the sound quality, but if it checks out this is the holy grail for low hassle, full sounding amplification and well-equipped mixer for keyboard/guitar/mic and BT audio and mixer control!
Also: you could probably get away with something like this for simply powering the keyboard, which has fairly loud speakers:

, which is 200wh and 300 watt inverter for $135
What I liked doing in smaller jam circles was to get my Pa1000 as loud as I needed and then bring up the volume of the speaker I used. That way I had wonderful stereo sound for myself, and an external speaker just added to the bass and overall fullness of the sound, and I was likely not to play too loud cause i had such great monitors from the built-in speakers on the keyboard
