Current Prime Day discounts stack on this one. After Promotional Code 8XR76RMA, price works out to $11.09 + tax. Sorry if posted elsewhere. Wasn't sure if "new promos stack on existing deal" makes it a new thread or not.
Note: you need to press the button once to turn it on, it does not have a sensitive load-sensing function like other power banks. So according to one of the review, anything that draws under 0.17A will NOT be considered as a load and the device will shut off after 15 seconds. This means you can't fully charge small bluetooth headset, or a "nitecore tube" keychain flashlight or power up a low current USB light, unless you have more load connected in the other port.
Also, if you leave your smartphone charge using this overnight, likely by the time you unplug and use the phone, it won't be 100% because once it is fully charged (probably at the middle of the night), the portable battery will auto shutoff and it will start using the smartphone battery again.
