Portable Solar Panels To Charge Electric Car

Bought this unit during the initial release and it is awesome. Still have the EF pros and they are great(certainly more portable), but the ultra us on a whole other level. 5.2k running my dryer just to test it and it wasn't even trying. Dead quiet@ over 5k watts. I currently have it charging with 3.6k of solar on the high PV port and it kicks on when the suns come up with less solar coming in than it takes to kick on my original delta pros!! My 300 watt folding solar panels just have to have decent sunlight to charge the ultra when the original delta pros won't charge unless the panels are in full sun conditions. Only drawback is you can't grab the handles and lift it as the unit just sits on the battery and is only connected/secured by the connecting cable. That being said it's purpose isnt to be portable, so if your your hesitating on getting this as a whole home backup, don't. Just pull the trigger. You'll be happy you did!

The Goal Zero Nomad 20 is a great portable solar panel. I haven't given it a lot of use yet, but already it works as intended. I am able to charge my phone off it when the sky is overcast. In direct sunlight, it charges faster. I was also able to charge a usb battery pack, that doubles as a car jump starter, while out camping where there was no electricity. This was handy, considering I drained my car battery running a waffle maker. Downsides? it doesn't come with a carrying strap, though it isn't hard to add one.

I purchased two of these units with solar panels for emergencies and have been using them to supplement electric bills while waiting for that big emergency. This is a win win for me. Am waiting for additional battery packs to ad to units. Performance so far is much better than expected.

Really satisfied with the Delta pro that I backed through Kickstarter. It really exceeded my expectations from it. Using it for my self built campervan as main powersource and it has all the handy features built in. Really convenient to be able to directly plug in your solar panels for charging and charging from your car alternator while driving. This product really delivers, only minor downside that I could find is not being able to simultaneously charge with solar panels and 12v car adapter. They use the same charging port on the Delta Pro. Overall great purchase and would definitely recommend! Great invention!

Very good so far , charge very fast Very good investment, my next purchase will be the solar panels

Ability to charge in car and more portable.than stock

Great portable power when needed. It’s a small package but can power a few essentials when needed. I will be purchasing another with more solar panels for power independence

We have been looking for a portable solar battery for tailgating and backyard football/movie watching. Watched and read many reviews and was excited when the Delta 2 came out and immediately purchased it. We already have 2-160w EcoFlow solar panels which we plan to use with the Delta 2. My only complaint is that although it can accept 500w charging, the 60 amp voltage limits it to 2 panels. Other than that, it is excellent and highly recommended.

Delta2 works like a charm! I test recharged it with the solar panels. Went from 51%charge to 100% in 2hrs 15 min on solar panels. Super pleased!

I received the delta unit last week as it took awhile to receive due to popularity ,the unit was packaged extremely well and looks very sturdy and made very well,also ordered the solar panels but will need another set as 1 set won't be enough to charge solar fast, the wall charge is extremely fast pushing 800 to 900 watts,the solar is only 92 watts so another set is required ordered the mc cables for additional panels. I keep the unit plugged into outlet when not in use per owners manual,2 Year's warranty for peace of mind,I researched hard on this product and canceled the blueetti to go with this purchase,so far very happy as only time will tell,Jeffrey from Wisconsin:)
