Guide 10 Plus
on March 22, 2013
I purchased two of these so I could charge AA and AAA at the same time, as my equipment requires both types of batteries. These work with my iphone 5 and my iPad 2. I purchased the 13.5 watt solar panel and it will only charge this off of the USB. The benefit is that there is more surface area on this solar panel and even with overcast, it continues to charge the Guide 10.
IMPORTANT!!! When you get the Guide 10, there is a small plastic tab that is on the first battery. KEEP THIS and when you are not using your Guide 10, put the clear plastic tab back between the battery and the bottom tab. The reason for this is, it keeps the unit from discharging your batteries. Your batteries will still slowly discharge, but if you don't put the tab back in between the battery and the terminal, it will discharge your batteries quicker. IMPORTANT!!!
With the tab in place, I have been able to retain 70% charge after several months. Using the supplied tab, I am able to charge the batteries up and store the unit for several months and still be able to pull it out and use it. I have heard others say that they pull the one battery out, but I don't want to take the chance of losing one battery. This way, everything stays in place and is ready for use.
Also, you might want to pick up another set of batteries so that one set can be charging in your backpack (with solar panel attached and hanging off the back) while you are using your other set in your gear. Eneloop makes a great 2000mah rechargeable battery for this purpose.
If you are needing more power, the Sherpa 50 is the way to go. Using both the Sherpa 50 and a Guide 10 plus for your equipment that cannot be charged off of USB and uses AA or AAA batteris, is the way to go.
