How much power do I actually need?

Most events need less than people expect. One thing worth knowing: we quote on powered hours, not event hours — a six-hour reception with a two-hour setup and a soundcheck is a nine-hour rental. Each battery holds about 5.5 usable kilowatt-hours — usable because a little is lost converting to household current, so we quote on the real number rather than the one on the box. Send us your list and we'll size it, or use the AI sizing prompt to get a starting estimate.

How quiet is it, really?

There's no engine and nothing combusts — the only moving parts are small cooling fans. It's manufacturer-rated under 30 dB, against roughly 60–75 dB for a typical portable gas generator. You can hold a conversation standing next to it, and a sound mixer can roll audio beside it.

The unit has to stay dry and under cover. If there's no covered spot at your venue, we bring a pop-up canopy at no charge.

A 50% deposit confirms your date, and the balance is due after the event. If you cancel more than 30 days out, the deposit is refunded minus a $50 processing fee. Inside 30 days the deposit is non-refundable.

Yes — general liability, and we'll send a certificate of insurance naming your venue as additional insured on request.

Do you work with planners and venues?

Often. We work directly with coordinators, bands and caterers so power doesn't land back on your plate — COI to the venue, early arrival, reachable on the day. If you keep a preferred vendor list, we'd like to be on it.

How far will you travel?

Within 20 miles is included. From 20 to 80 miles adds $100. Past 80 miles we quote individually. Jobs have taken us out to Loudoun County, Virginia and Cambridge on Maryland's Eastern Shore, and we cover the Richmond area too — that's a sample, not a list. If you're farther out than that, just ask.

What days do you work?

Friday evenings, Saturdays and Sundays are our standard event days — that's when most of what we do happens, and those dates go fastest. Weekdays are available by request; just put the date in and we'll confirm. If you've lost power and need something today, don't use the form — text us at (202) 524-3113. We'll tell you right away whether we can get to you.

Can it be moved once it's set up?

Not without checking with us first. We agree placement at setup so the cable runs and the load are right.

Do I need to do anything on the day?

No. We roll it in, position it, plug in, test under load, and show your people where their outlets are. Then we come back for it.

Most events I do land in one of three setups.

That's not a rule — it's what I've found after a year of weddings, festivals, DJ sets and backyard parties around the DMV.

Before your date I'll go through what you're actually plugging in — with your DJ, your band's tech contact, your caterer, whoever it needs to be — and we'll land on an exact equipment list. If that means you need less than the package, I'll tell you. If it means more, I'll tell you that too, before you've paid anything.
