Goal Zero Guide 10 Power Pack
Historic Range: $29.95-$34.98
Reviewers Paid: $40.00-$50.00
The biggest "con" to the Guide 10 Power Pack is that the consumer is left to guess whether or not his/her electronic device will be compatible. Goal Zero does warn that not all all electronic devices will work well with their products, but it's a $50-gamble for the consumer to take.
- Good customer service
- Only works with some devices
- Does not perform to its published claims

1/28/14 My email to Goal Zero (8:00am)
I purchased the Guide 10 Plus to go with the Nomad 7 Solar Charge I had previously purchased. I have now tested it twice, and I can't get nearly the performance out of it that is listed on the website and in the printed material that came with it. I have charged up the pack to 100% twice using a USB connection to my computer. The first time, I charged it up until the light turned a solid green. The second time, I left it connected overnight (a full 10 hours).
I own a Motorola Razr (not the Maxx). In both tests, the phone was kept dormant throughout the charging period, except for a quick battery check every 30 minutes to see where it was at in the charging. On the second test, I disabled both WiFi and Mobile Data to further conserve batter life.
On the first test, I ran the phone's battery down to 3%. I connected it to the Guide 10. After ninety minutes, the Guide 10's light was a solid red, and the phone indicated it was no longer receiving a charge. It was charged up to 61%. This morning, I connected my phone at 1% and the Guide 10 charged it up to 68% before stopping.
Normally, I wouldn't be disappointed with this performance. I can get a lot done with 68% charge. But the technical specs state the Guide 10 will charge a 5-7watt smartphone twice, and I'm not even getting one full charge. What am I missing on this?

Thanks for contacting Goal Zero! Sorry to hear you are experiencing issues.
-Did you remove the plastic ‘pull’ tab between the batteries and the Guide 10 Plus?
-Are you using the Goal Zero NiMH AA batteries?
-Have you tried charging other USB devices? Are you getting the same result?
I look forward to helping you!

My response 1/28/14 (11:15am):
Thanks for the quick response. I wasn't expecting to hear from anyone so soon. Regarding your questions, I have removed the plastic tab, and I'm using the unit exactly as it was sold to me (with the Goal Zero NiMH AA batteries). I have not tried any other USB device.
Am I misunderstanding the expectations of the charge? Do the batteries need to be charged and drained a few times to reach maximum efficiency? Could the pack or the batteries be defective?
Thanks for the help.

Can you please provide your physical address and contact information? We have found that some Motorola phones have trouble recognize the USB port on the Guide 10 Plus as a charging device.
I would like to send you a USB Smart Adapter which will allow your phone to recognize the device. You can view the adapter here: http://www.goalzero.com/p/200/usb-smart-adapter
Thanks for your patience!

Technical Description from provided website:
Phones have different needs when it comes to charging. The phone checks its power source to be sure it will not by damaged by over powering and sometimes to prevent it from charging from different brands of chargers. Almost all devices are different when it comes to this. The Smart Adapter will communicate with the two, the power source and phone, and make the correct adjustments to the power source meets the charging requirements for the phone. The thing is that currently ALL USB ports are 5v, but some devices want 0.5 amps and other want up to 2 amps, the smart chip will sometimes tell the device what to expect so that it know and will then accept the charge.

Very well thought out piece of gear. Will charge my phone two times with a full charge on the Guide 10. On a cloudy day might be lucky to get half charge, but guess you can't bet that. I mean it's all free energy.
I really think Goal Zero did a great job!!!!
