    This was a great purchase, is very easy to use and the display is easy to understand. I was able to charge my laptop from dead, charge my phone, and run a mini 100W heater for 45 minutes off it (I didn't do this all at once) Looks like charge time via wall plug in and via car are both 5 hours. I'm very happy with the product, but debating returning it for something with more watts so that I can get more done in between charges. Haven't decided yet, because for $160 and 300W thats a pretty good deal and I'm very happy with the product

    When we lose power due to storms or snow/ice, the Power company usually gets us up in 2-8 hours. This portable power was able to run my laptop and monitor as I used my cell phone as a hot spot. Worked beautifully for 6 hours (could have gone longer) until the power was restored. This saved me a PTO day.

    We use the Square Stand and Square Retail with an Epson Receipt Printer and Card Reader. We purchased this battery to help us when we go to festivals with our mobile sales booth. I read the specs for this product, and measured the power needed for our POS system, and made an estimated assumption that it would power the POS for about 8hrs. Well it far exceeded my expectations. In the two times we have taken it out with Moderate to Heavy usage, we have managed to run all day (9+hrs) and on both occasions the unit still had over 70% life. Really smart decision.

    Since I received this I have used it for so many things. We live on a small farm and it is great to have power move around with me. This is a great unit and a really good price

    Product is excellent, and works perfectly for my needs! Charges all my devices when I’m off the grid camping. Paired with the 60W solar panel these thing is a real power house! Travel size with full size power!
