Goal Zero Yeti 400 Lithium Portable Power Station (Open Box)

Does the job.

I take this camping and it charges my phone, tablet, and even a small fan. It's compact and easy to carry. The open box I received was in like-new condition. Great value for the price.

The Yeti 400 is fine for charging phones and USB devices, but it struggled to run a mini cooler – it only lasted about an hour. It's good for what it is, but don't expect to run large appliances. The open box was fine, but I wish I had gotten a bit more power.

I use this to power my CPAP machine during power outages. It lasts about two nights on a full charge, which is perfect. It's lightweight and easy to store. The open box came with a small cosmetic scratch, but it works perfectly. Good purchase.

I've had this for a few months and it's been reliable. I take it to the track to charge my drone batteries and phone. It's lightweight and the display is clear. The open box deal was a steal. I'll definitely buy more Goal Zero products.

The Yeti 400 charges my devices fine, but it takes a while to charge up itself – about 6 hours from wall, and it doesn't support solar charging as fast as I'd like. But for the size, it's okay. The open box was in good shape. Overall, a solid product.

This little unit is perfect for my needs. I use it to power my reading lamp, charge my phone and laptop, and even run a small TV. It's quiet and efficient. The open box was in great condition. I'm very happy with the purchase and would recommend it to others.

It's okay for basic charging, but the battery drains faster than expected when using the AC outlet. For the price, I expected a bit more. The open box unit was fine, but I'm not impressed with the overall performance.

I use this to power my small TV and speakers during tailgates. It lasts about 3 hours with the TV running, which is enough for a game. It's compact and easy to transport. The open box had a few scuffs, but that's fine. Good buy.

I bought this open box to use in my RV for charging devices and running small appliances. It works like new. The battery holds a charge well, and the ports are convenient. I'm very satisfied with this purchase. It's a great value for the price.
