Ordered the item around midnight, it was delivered early evening within the day. I am impressed with the fast delivery and how the item was properly package, received it in perfect condition.
The item came 75% charged so I decided to charge it to 100%, it took close to 3 hours to charge using a regular 5V USB adaptor. Used it the next day to inflate all 4 tires from 24 to 34 psi, it was easy %26 smooth process, it used up 25% of the charge to inflate all 4 tires. Fortunately I had this jump starter on hand since my car wouldn't start all of a sudden. Attached the battery claw attachments, within seconds light indicator displayed green, turned on the ignition, car started easily, the charge still sat at 75%. I'm so pleased with this purchase, it came in handy at the right time, saved me from calling CAA for assistance.
I highly recommend this product !
