User questions & answers

Question:	It says in the discription to not leave it in a hot car to charge. is there an issue with leaving it in a hot car when not charging
Answer:	I personally do not know but... I found the following in the internet: Avoid Prolonged Exposure to Intense Heat and Cold Leaving a battery-powered device in your extremely hot car for more than about 2 hours can not only permanently shorten the battery's life but also damage other parts of the device, including the LCD screen, the plastic case, and the glue holding it together.Aug 1, 2007
Question:	Battery pack is stealing power from my phone, not charging my phone. What am I doing wrong
Answer:	Check the plug in situation. You might have it set up backwards?
Question:	Can this be brought on an airplane in a carry on bag
Answer:	Based on my researching this question, and as I am buying this specifically to bring on a plane (camping in remote area of Panama), the answer is yes, it can be brought on a plane. I am not sure why the other answer was "no". This is less than 100 wH lithium battery and FAA regs say anything less that 100 is OK. HAVE TO BRING IT IN YOUR CARRY-ON-not in checked baggage. Here is how you calculate the wH. mAh/1000 X 3.7 = wH. This has 25,000 mAh. 25,000/1000 X 3.7 = 92.5wH.

• Cell type: Monocrystalline
• Degree of efficiency: 22%
• Output: 1x USB with 6V 1.1 A equaling 6W (max. power)
• Dimensions: 21.3 x 8.7 x 15.4 in

• Important note: The solar panel performs best in direct sunlight. In changing sunlight, the output performance of the solar panel can vary. We recommend the use of a buffer battery (e.g. XTPower XT-13000). In this case, you charge the intermediate battery with the solar panel. The intermediate battery provides a constant charging power.
