Wow I just returned this at $220. This is an even better deal. I hope folks who bought it at that price go back and get the price match or return and rebuy.

bought the model without the battery packs on Amazon for $190 during a sale, but $10 more with battery packs is a good price, esp from Costco. thank you

Our community has rated this post as helpful. If you agree, why not thank SharpTent6356

I LOVE this unit. I paralleled to two 100W panels to give me about 165W input. It runs my garage tv pretty much all day when the sun's out at a net gain of power (tv only uses 100w). And I use the two power blocks to charge cellphones over night. Such an awesome unit and price!!

Got it few months back, how long is the price match guarantee?

the refurbs with much larger batteries are a better value

wait for a sale on refurb delta3-1500 which is typically most battery per dollar

mine was $450 so FIVE times the capacity for ~twice the price

This is true. I got a refurb Delta 2 Max a while back, I've yet to run it down to zero.

These smaller units are pretty convenient depending on use case, though. I use mine to power a dash-cam set-up in my truck around the clock, so I'm isolated from my starting battery and not draining it. It gives me AC power on the road, as well.

Interesting combo! I purchased the River 3+ many months ago from Amazon. That version did not have the wireless charging capability. I use it as a UPS and it serves that function really well.

From Costco, it's 30 days. If you bring it in and tell them you're planning on returning + rebuying, maybe they'll save you the hassle. But they may not honor the online price, if it's not available locally.

Out of stock at my local warehouse, but I got it shipped for free at that price to my house.
