Bests & Worsts Reviews from Amazon

The Yeti 400 makes a heavy paperweight! Arrived with a defective AC inverter. I read the other negative reviews on amazon and believed I would not have the same experience. But I was wrong. It takes a long time to charge which you must do immediately out of the box. It outputs in DC and USB, but the AC output was dead with a fault reading on the display "AC!" The manual and Goal Zero customer service indicated that I should try the following troubleshooting methods: a. turn the AC button on and off b. remove all connections, open the battery box, and disconnect the battery to reset c. press down the AC button for 30 seconds d. or press down the display button for 30 seconds. None of this worked. So I contacted customer service again to repair it under warranty. Customer service at Goal Zero picks up there phone and is responsive on the phone. But they asked me to email them my concern and contact information, along with the proof of purchase from Amazon. No response yet - not even an acknowledgement - just radio silence. This is not a returnable item through Amazon. Amazon instead offered an full refund or replacement. I had purchased this for an upcoming camping trip. With no immediate resolution in sight, I went ahead and purchased the Atoto Lithium Ion Portable Power Station instead of another Goal Zero product. I called Goal Zero again, this time to ask if they had a solution to connect the two nomad 20 solar panles in the kit to anderson adapters or even to MC4s for the Atoto PPS. The answer by Goal Zero customer service was simply NO and that the Nomad 20 panels were basically for this goal zero product, which was defective. It takes 8mm connections. Save your money and purchase something else. Goal Zero seems to be everywhere on the internet when it comes to portable power supplies. I had hoped they produced a reliable product. But I see from the other many reviews that this is not the case. I share in the frustration expressed by many. The replacement product that I purchased, Atoto PPS, is similarly rated as 400 watts, is much more lighter because of the the lithium ion batteries, is comparably priced to the Yeti 400, more portable, and most importantly works! I would recommend anybody that asks not to buy this product.
