The "Guide 10 Plus" is a very versatile USB power pack. You can charge up its internal batteries (4x AA NiMH) from an USB power source, or from a solar panel (such as the Goal Zero 11800 Nomad 7 v2 Solar Panel). Once the internal batteries are charged, you can then power its 5V USB output port to recharge other USB devices, such as cell phone or tablet. In case of emergency, you can even insert 4 disposable alkaline AA batteries in it, just to recharge your essential USB-powered devices. Finally, it comes with a handy little LED flashlight.
The 4 included rechargeable AA NiMH batteries are advertised as '2300mAh' and are pre-charged (low-self-discharge) type. Both claims are accurate according to my measurement with the La Crosse BC1000 Battery Charger/Analyzer:
- Right out of the box, the average remaining charge was 1927mAh
- After just one Recharge/Discharge cycle, the average capacity jumped to 2360mAh
- After two more cycles, the average capacity settled at 2368mAh.
Just for comparison, the eneloop AA is only rated for a capacity of 2000mAh.
The Guide 10 Plus spec sheet says 1A max output from its USB port. In actual testing, I was able to draw up to 1.3-1.4A from its port - as least for a short duration (I don't want to risk burning up the power converter inside). This means the unit can be used to recharge most smart phones and small tablets. On the other hand, you should not expect it to power up your iPad or Kindle Fire, as those require at least 2A of current.
I connected a 5 ohm power resistor to the USB output port, and recorded its output voltage and current over time. The unit was able to generate 0.99A at 5V (or 4.95W) for 102 minutes, which corresponds to a total output energy of 8.4Wh (4.95*102/60). This is consistent with the energy stored in four AA rechargeable batteries (4 * 1.2V * 2.3Ah = 11Wh), if we assume the energy conversion is only 75-80% efficient.
The product description claims that the unit can "recharge your cell phone 1-3 times". This sounds overly optimistic. My Samsung Galaxy S3, for example, has a battery pack rated 3.7V 2100mAh, or 7.77Wh. So the total output energy of 8.4Wh from this power pack is barely enough to fully recharge my S3 just once, after conversion losses.
Just for comparison, the Jackery Bar 5600mAh Power Bank is able to provide 19.8Wh of energy during my test, enough to give my S3 two full charges. The Jackery bar is also much smaller, lighter and cheaper than this Guide 10 Plus unit.
#1: The product description did not mention whether the unit charges 4 AA batteries individually or in pairs. What I found out from my testing is that it must charge all 4 cells at once. If I connect the unit to a USB power supply with just 2 or 3 cells inserted, the red LED starts blinking as if the batteries are being charged, even though they are not.
#2: The charge-termination method seems unreliable. The first time I tried charging 4 AA cells, the unit drew 0.78A from 5V supply for 2 hours, then the LED turned solid green to signal charging was done. But those batteries were only charged to 50% capacity according to my BT-C2000 Battery Charger Tester Analyzer. The next time I restarted the charging process in the Guide 10 Plus, the LED stopped blinking after 4 hours, and all batteries were charged to 100% full. I still can't figure out why the charger terminated prematurely the first time.
#3: I connected the Guide 10 Plus unit to a USB power source, with the intention of using it just as an LED lamp. But if I don't have 4 batteries inserted, the LED light pulses every second, making it unpleasant to use.
Overall, this Guide 10 Plus unit works as advertised... mostly. Given its high price, I am disappointed by those design flaws mentioned above. So 4-star is the best I can give it, and that's only because I got the package for a good price during an Amazon Deal of the Day sale.

Just in case you want to know how well the Guide 10 Power Pack works with the Nomad 7 solar panel, see my review on it for details:
Able to be shipped over seas to APO addresses. Sent to my brother at a military address. You cannot send lithium batteries via mail anymore. So this is your best option if you want something over there.
You can charge items from the pack itself, or you can charge individual batteries inside it, and use those in items as well.
They have a lot of accessories that can be used with this as well.
It's not the largest or faster charger out there, but it does a lot for you.
The only Con is you need to have 4 batteries in it to use charge the batteries. But, I've seen some work arounds for that.
In my opinion Goal Zero is a solid company with great goals. They stand for something more than just making a dollar. Are there cheaper alternatives? Yes, but you wouldn't be backing a company that cares about getting lights and power to third world countries.
You should buy this and keep it in your pack, just in case. Also, get a solar panel from Goal Zero to keep it charged up for free.
UPDATE: Bought it 12/03/16,I have used this in the house 3 times, doesn't work already. I can't charge a device with it nor can I use it as a battery charger. The led flashlight works,but switched on to charge my iPhone the indicator light doesn't come on. Hopefully GZ will replace it. (I have used 3 different sets of batteries that I know are charged.)
After fiddling with this for about half an hour, the on/off switch appears to be the culprit. It appears to function intermittently.
GoalZero customer support says they will send a replacement. awesome! The replacement arrived in 2 days. Thank you
