## Customer Reviews

### ⭐⭐⭐⭐⭐ Great 9 volt recharge option
*by C***0 on May 16, 2025*

These are super easy to recharge and hold a charge long time for our medical pain device.

### ⭐⭐⭐⭐⭐ 💛
*by R***N on April 6, 2025*

These work great. For them for my husband as he plays guitar and needs runs through batteries like crazy. Haven't had any problems yet they're pretty awesome :)

### ⭐⭐⭐⭐⭐ They Work Exactly As Specified - Which is not always the case!
*by J***S on June 1, 2024*

Played my first three set gig with the Kratex powering my (as measured) 134 mA Tonex One. I also tested it at home and it was going strong after 4 hours of continuous operation of the Tonex. Seems to meet their spec at roughly 1.5x the watt-hours of a standard alkaline 9v battery.It also charges at a 10 watt rate which is 4x what the next nearest battery of this type I tried. When it is fully charged it completely stops taking any current from the USB power source. The battery seems to fully implement USB C orientation protocol, which others of this type do not.It does operate at a very slightly lower voltage than a fresh 9v alkaline, but well above what an alkaline would fall to inside its useful lifetime. This was implemented in the interest of being compatible with older 9v battery chargers, which I don't own and did not test. But what I did test was whether it could power any of my collection of guitar pedals, and it at that task PERFECT!
