Q: Once you charge the battery with the USB if not in use how long does it charge stay

If it's not attached to the pump, the charge should hold indefinitely. I'm not sure how to put a timeline on it, but it functions like any other battery in the way that if it isn't discharging it holds the charge as well as the quality of the cells being used. Over time charge will diminish slightly, and slightly more if left attached to the pump, but this would be very slight. Think of it like the Duracell batteries you see in the store that say "5 years guaranteed" what that means is that the battery is rated to hold it's charge for five years. Unfortunately, I couldn't find any documentation on the cells used in this, but it's the same principle and the charge should hold for quite some time if it's not being discharged. (Also, to preserve the batteries life, if it's not going to be used for say six months or longer, it should be discharged to about 30% to protect the longevity of the cells when a charge is needed). Hope this helps a little!

Q: how long to charge for full charge

Hi customer, the battery will be fully charged within 4 hours if using a 5V 2A charging block. Please contact us via the Amazon buyer message if you need any further help. – Best wishes! -AstroAI

Q: Can you charge your cell phone with the USB connection on the battery?

Hi customer, thanks for your question. The rechargeable battery is suitable for charging your low battery electronic devices (such as smartphones or i-pad ). If the rechargeable battery is short in power, please charge it as soon as possible instead of continuous use.
