DO NOT PURCHASE DIRECTLY FROM AMAZON!
on January 24, 2012
There was a bad run of the power packs that would heat up and melt. GoalZero has corrected the problem months ago and sent out new power packs that are labeled "GUIDE 10 PLUS" in the indention below where it says GoalZero. The old defective power packs just say "GoalZero" with nothing in the endintion. The word !PULS! tells you that you have the re engineered power pack. Amazon's stock of GoalZero products are the old defective power pack that will heat up and melt. I ordered one on January 20, 2012 and got the bad power pack. After talking with customer service, it is evident that the old stock will be shipped until it is exhausted. They were very helpful in refunding my money without requiring the product be returned. Make your purchase from Amazon THROUGH one of the other sellers listed on the right. I contacted Blue Kangaroos and they are aware of the problem and HAVE the new power pack ready for shipment.
Update 2/3/2012:I have both the old and the new power packs now and have additional information. I was told by GoalZero Tech Support that some of the old power packs, the ones that DO NOT have the word "Plus" on the label, were modified before shipping and will not heat up. The only way to know if yours has been modified is the pry the end cap off of the Power pack. The end cap that covers the plugs and LED. Just take a small screw driver, put it in the grove and twist, it will come off. Behind the LED there are three large resistors [the large gray round things with color bands on them]. If none of the color bands are BLACK, this power pack has been modified and WILL NOT heat up. I have verified this. Mine has no black bands and does not heat up. GoalZero will still send you a new power pack and batteries if you request it. There is a slight functional difference between the Old and New power packs. The "Old" will charge devices through the USB port at about a 300ma higher rate than the New "Plus" power pack and will charge the batteries a little faster. This is because the old Power Packs have the Data+ and Data- lines connected together which tells most devices to accept charging at a higher rate.
