User questions & answers
Question: | For the 12V barrel connector outputs, are they center - or |
Answer: | The center pole (deep inside the bottom or back of the outlet) is the “positive” pole, while the metal shell (or metal clips inside the socket on the sides) of the outlet form the negative pole. |
Question: | How do I upgrade to charge at 60 to 72 watts |
Answer: | I believe that you can charge with solar & ac & /or power port at the same time... The power station should "safe" itself if anything is wrong. |
Question: | Can the Rockpower 300 be charged while using |
Answer: | Rockpower 300w cpap camping power supply can only be charged while using for dc and usb port. But it cant be charged while using for AC to prolong the battery life. |
Question: | after 500 life cycles what % is remaining |
Answer: | With respect to "is it chargeable to 100% and on the 501st cycle, it will only charge to 80%" by username Amazon Customer: No. You'd still see "Charged to 100%" but the capacity at 100% would now be ~80% what it once was when new. Nothing to do with management systems or software. It's the inherent chemical and mechanical degradation in each cell, caused almost exclusively by basic charge cycles (namely, the latter 20% of the charge cycle, for lithium batts). It's normal wear and tare from charging... even in ideal circumstances and cool temperatures, it's unavoidable damage, but partially mitigated if you keep your cells under 70-80% state of charge (max); would be true if you stopped charging a powerstation, at 80% every time. Then it will take 3-4x longer to see the same degradation in that device's battery as 500 charge cycles worth, but still, unavoidable in the end. Same would be true for any device's battery, as long as it's a common lithium chemistry. That's why it's terrible to top-off cell phones, tablets, Nissan Leaf's, power packs, etc. because the latter 20% of charging costs like 60% of a full charge's wear-cycle. Keep that in mind and you'll have a much better time with electronics. :) Best of luck to everyone. |
