Really great start! Good batteries. Good recharge. Nice charging unit. Well designed. Want to see what longevity is like, but impressed so far!

Great product. Takes the hassle out of having to change batteries in every day products.

Good product, well packaged and easy to charge. Looking forward to seeing how they perform over time

These batteries are a little more expensive but they are the best I have ever seen. They are easily rechargeable with the chord plugging directly into each battery and then on a USB or C port. They charge up quickly and they keep their charge for a long time. I used the AA format in a battery operated tooth brush and the batteries lasted weeks. It is quite impressive.

Very well-made batteries. Included charger is very convenient.

Akkus sind in der Nutzung gut und halten vergleichbar mit einfachen Batterien. Kein Problem beim Aufladen. Etwas teuer.

I bought these little gems as I'm sick and tired of adding to the unnecessary resources required to service my needs.

Also customer services are awesome.
I had a question regarding charging requirements and I was told my batteries would get updated withiut having to throw them away.
Outstanding. First class product, first class customer service, first class company! 👍

it took few hours to fully charged. batteries are light.
great eco-friendly alternative to single use batteries.

I bought different types of batteries, all charged full within few hours.
Great choice for kid toys, that require new batteries every few months.

Batteries seem to keep their charge very well and are easy to recharge just by plugging them onto a USB port with the cables provided. Well worth the purchase and good for the environment.

In kurzer Zeit geladen, so gut wie keine Selbstentladung – bessere Akkus kenne ich nicht.

CR123A USB-C Rechargeable Batteries

AA & AAA Sustainability kit

I got these for my electric guitar, which has a piezo bridge. I had previously tried conventional NiMh rechargables, but these tended to be over-sized and not fit properly in the battery compartment, meaning it did not close properly. I tried another cheap USB lithium rechargeable solution, but the voltage converter (I assume) introduced constant high-pitched noise that made it unusable for the guitar. I had almost given up, but found these. They are actually the correct size, and don't introduce noise! The piezo does not draw a lot of current so I have not ran the battery down to report on their capacity, but it has lasted a few months with no signs of stopping, and with everything else I am inclined to believe their claimed capacity. They cost more than other solutions, but it is worth it as the size and components are clearly better than competitors.

I bought these to use with guitar effects pedals, which in the past have not worked well with rechargeable 9v batteries, either because other batteries don't actually deliver enough power, or because they're not quite the standard size. These Paleblue ones work perfectly. They're the exact right size 9v is meant to be, and although I can't measure the power exactly, they are powering everything correctly. The time they last depends on the particular pedal I use them with, but even the most power-hungry pedals are lasting a couple of hours with them, which indicates the capacity is as much as Paleblue advertise. Recharge time has been quick, too. I'll certainly be buying more.
