Best Portable Solar Panels And Charger

[882 Wh] 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

[Battery] 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!

[Black] I hooked up the solar panels to the charger today. The panels and charger are on my in full sun. Started at 29% battery and now is at 42%. Charges at a slower pace. It’s been charging for about 2 hours. I have four panels for 400 watts.

[1.35 lb] Great solar panels. I was surprised how well it charged.

[Monocrystalline] Great solar panels Love the quality and the performance

[1] I have an HOA that does not allow Solar Panels to be permanently attached to the property. To get around this, I manually set up solar panels every time it needs a charge. I like using the Delta 2 Max to power my PC setup, and this extra battery gives me more days between recharges. Given the added convenience, I will be using much more solar in my day to day life. I LOVE the storage compartment, I will never loose the cable with this! My only complaint is how much solar energy input does not transfer to charging, but I recognize this as a limitation of the technology. I didn't find this information in any of the reviews, so I'm placing my findings here. Of course your results may vary, but I have observed approximately 87% of Solar Input converting to Battery Input.

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

[29 lb] Best portable screen.
