Customer service is excellent; product it's very good
I bought this a year ago. I recommend you do the same. The solar panel: works well, but I live far north and the sun just doesn't have enough energy unless it's a beautiful day to do anything more than maybe charge your phone over the course of the day. Nothing is wrong with the product, it's working perfectly. I just don't live in California. I personally bought a much larger solar panel, because on days where it's gloomy or over cast where I live, you need an exceptional sized solar to get any kind of energy. Again, the product works perfect, my energy requirements need a larger panel. If you live anywhere where it routinely hits 80+ degrees f, this thing will work perfect to charge your battery up quick. If you live in say Washington, with the overcast and lower amount of energy in the sun it would probably take 2 days to charge up. Do some mental math and see if the panel could work for you. It's very small and could clip on a backpack, so it could function while being mobile. Free charging. I went with a larger setup that is packable, but when deployed cannot be mobile. Joys of living in places that just rain and the sun doesn't have as much energy. Now for the battery. It's the bread and butter. I love it. I used drill batteries with a USB adapter in the past, but my batteries kept going under voltage since my adapter was just some Chinese knock off and was permanently killing my expensive drill batteries. That's when I decided It was time to upgrade to something that will last a little longer. So I got this. It's great. Small enough you can bring it with you on any kind of camp trip, big enough to last you at least a weekend of phone charging. The inverter works perfectly, but you lose roughly 30% of your energy from inverting from DC to AC. If you can, try and use USB for everything. Most of our devices that are mobile are DC. Try not to invert from DC to an AC charger, since it's just going to invert back to DC to charge your phone. Use the built in USB sockets. I run a very small portable AC projector off of it and it will last about 4 hours, or I pump my air mattress up (pump is built in to mattress, queen 14" thick) and can do so about 2-3 times. The customer service is amazing. I was having a technical difficulty trying to learn how to charge it, and they sent me a new battery immediately. I honestly didn't even ask, they insisted. I love doing business with companies like that. The battery was past warranty, so they had no reason to ship me a new one, other than they stand by their product with excellent customer service. I can forgive issues with products but I would never forgive poor customer service. All in all, this isn't the setup for heavy glamping. This is for a family to charge phones on a weekend camping/float trip, or power 120v device a few times. If you need more, I wouldn't hesitate to shop this brand and look at larger options. This is also good for a group to bring instead of everyone bringing their own individual mini power banks. The weight to MAH rating is better to go with larger batteries. Rough estimation, I can charge my Google pixel 7 at least ten times off of one battery. If it's a perfect sunny day, I can charge my phone purely off of the solar panel in about 5 hours. Instead, charge the battery so you can use the phone, and transfer that battery power into your phone while you sleep. Perfect combo. Read more
