These are perfect 9 V batteries with an amazing USB charging function
It is a novel way of charging these batteries using a USB port. I am super happy with the function of these batteries and I am using a number of these in smoke detectors. To tell you the truth I am still amazed at the USB charging function for these 9 V batteries. These batteries have performed flawlessly for me. I only wish that I had known about these batteries sooner.

Not reliable
Batteries made it through 10 to 15 charges. After charging further than that, battery started to lose power and remain dead upon use.**Update. Changed to 4* because of customer service.

Long life
I use this in our door alarm sensors. Now they last a lot longer and reduce time spending charging batteries. Even came with a twin charge cable. Nice touch.

Real Junk
I do a lot of battery testing for use in various products. I have tested pretty much all available brands of lithium-polymer USB rechargeable batteries currently available on amazon. I bought a pack of 8 of these about 2 months ago and tested them.Results:2 of 8 failed to work right out of the box6 of 8 did take a charge the first timeWhen used in a device, all 6 lasted much less time that older 9V Li-Po batteries that were rated only at 650 mAh. I conclude that the real capacity of these batteries is more like 350-450 mAh, not 1300 mAh as advertised.Upon recharging, additional batteries began to fail.After only 4 recharge cycles, all but 2 of the original 8 batteries have failed and will not take a charge, and will not deliver usable power.I would not buy these batteries again.

Appears to be non-standard "USB-C"
Claims to be "USB-C" but doesn't work with my standard USB-C cables like other devices. Had to use the tiny cable it comes with to charge it.
