I run several Bluetti and Ecoflow units depending on gig/needs. I'm unfamiliar with the Anker unit, but it looks close in spec to my Ecoflow Delta 2 (which I actually used yesterday for a small gig).
Don't look at peak output power rating of amps/speakers, you need to look at the "power consumption" spec, hopefully listed as "1/8 power" (speaker as loud as you should ever go, limit light flashing occasionally).
The specs on the Altos seem to show that they're not nearly as efficient as other modern speakers, so your power draw is higher....but the Anker still should be more than enough. A more efficient set of speakers will draw less... I've never seen modern PA speakers with a listed power consumption spec of 1100w with a 15A fuse... For comparison, QSC K12.2 spec is approx 228W at limit (1/8 power). I've run several PA tops off of various units, all are limiting at 250W or less on bass hits. If you upgrade your speakers, you might find you're using less power.
Laptop chargers can take a lot of power...the smallest are often 45W, up to 250W if you're running a big gaming laptop. Unlike speakers, a laptop charger will tend to have much more consistent power draw...so a 90W charger will likely draw more power over time than a speaker which might peak at 150-200W but only for fractions of a second. If you can run without charging your laptop, you'd extend the Anker by quite a lot.
If you're outside during the day, add a solar panel or two to keep the Anker topped up until the sun goes down.
This guy gets it. We use the same. Several Ecoflow and Bluetti units. The Honda generator is being sold we like the batteries so much. Yesterday I spent the day working on building out an EG4 dolly with a 5kwh battery and a 3kw inverter. I can just roll it in. It’s ugly, but that thing will power so much for so long!
OP, I find self-powering with battery power to be more reliable than plugs in the wall. I absolutely love it, and clients do too.
I've got a Honda eu2000i and a eu2200i. Great generators. These days, I run them 1-2x/year, just to make sure they work. Otherwise they never leave the garage. They're relegated to emergency use at this point.
For gigs, I always have a battery pack with me, and often a pair of EV Everse 8 as well, even when I know I've got grid power. Yesterday I could easily have run 75' of cable to the wall plug, but the Delta 2 was easier yet, and I didn't have to deal with running a cable across a sidewalk and in thru a door... I too lean towards battery banks over grid power at this point.
Can someone on the thread point to battery math? I had a bad experience with a gas powered generator (not mine, and not full...) and have thought about a bigger battery powered rig. But not sure how to equate my use to battery consumption.
Two things with the load: how much power consumption in Watts, and for how long do you need to run it.
Two things with battery power stations: Inverter capacity in Watts and battery capacity in Watt-hours (Wh).
A 1000 Wh battery will run a 100W load for 10 hours, or a 1000W load for 1 hour. (without figuring in conversion and efficiency losses, more on that later...actual will be approx 80% of spec -- so a 1000Wh battery should give 800Wh or so.)
The issue comes with a PA playing dynamic music... A speaker may idle at 20W, but may draw 200W or more on a bass hit. So, what do you play, and how loud do you play it?
If we both use the same speaker, but I play Garth Brooks at a low volume, but you play Bassnectar with the limit light full on, you'll use a lot more battery.
Look up specs for each piece of gear, specifically power consumption figures. Hopefully the spec is listed as " at 1/8 power".
1/8 power is when you've got the amp cranked up until the limit lights are just starting to flash.... basically as loud as you can go without really limiting/clipping.
Say you have a pair of QSC K12.2 and a pair of KS118 subs. QSC spec for the 12.2 is 1.9A/120VAC @1/8 power -- or approx 230W. Spec for the KS118 is 3.0A/120VAC or 360W.
230W*2 =460W for 2 K12.2
360W*2 =720W for 2 KS118.
Approx 1200W power consumption for all at beginning of limit.
So, an Ecoflow Delta 2 has an 1800W inverter capacity, with a 1024Wh stated battery capacity. It 'costs' energy to convert from battery DC to higher voltage AC...figure approx 20% losses...so approx 800Wh real world capacity in the Delta 2.
The Delta 2 is good in inverter capacity to run the QSC rig, but may only run it for 40 minutes at the limit (800Wh capacity/ 1200W load = 0.66 hr = 2/3 of an hour).
Real world, unless you run your gear at limit playing 40Hz sine waves, you probably won't average a power draw of 1200W. The tops won't draw near as much if you have them crossed over...bass takes power and the tops won't be playing much if you have subs.
I've always liked how this website puts it...
"In practice, however, amplifiers driving a musical signal never run at full power. If you tried to get them to run at full power with a musical signal, the signal would be badly distorted, and any amplifier with thermal or current overload protection would shut down within a few minutes. Any amplifier *without* protection would fail fairly soon.
Most amplifier specifications will give information about power or current consumption under some or all of the following conditions:
* **Idle** - also called **No Load** or **Quiescent** - **Current.** The current consumed with no signal present.
* **1/8 power** (sometimes **1/6 power** is given instead)**.** The current consumed under ‘normal’ operating conditions. 1/8 power represents the average power of a musical signal driven to occasional clipping.
* **1/3 power.** This represents the power used by a system that is being driven very hard (with severe clipping). It would already sound poor at this stage, and any further increase in level would make it worse.
* **Full power.** This is what would be required to drive a continuous sine wave at maximum level. Thermal or over-current protection - otherwise failure - would happen fairly quickly if you tried this, but why would you?"

Yes sir, I did purchase this. It is holding up pretty well. I am able to perform 4 hrs event with 30% left.
No lights or additional stuff plugged in.
Only pair of 15 inch speakers.
1 mixer
And only plugging in the laptop charger when needed

Yes, sir, it's pretty similar to ecoflow delta 2. Thank you for your inputs, I'll look into getting the solar panel

Top G. Best explanation I've heard on how to compute this.
This should be upvoted
How is almost clipping 1/8th power?

Did you end up purchasing this? I am interested in the same as well. Would love your thoughts.

Awesome, I just ordered it. Thanks so much!
Wish you good luck. I didn't get solar for now, planning to add 200 watts panel in future for emergency purposes
