Paleblue USB Rechargeable AAA Lithium-ion Batteries, 1 Hour Charge Time, Recharge Over 1000 Times, 600 mAh, 4-in-1 USB-A to USB-C Charging Cable, 4 Pack

a little expensive but so far they have lasted a long time on a single charge, 1 cable charges all 4 batteries at the same time.. just get a decent power supply so they charge up in a little under an hour

these batteries are very useful. even with a device that take two, the other two still hold a charge for use.

Better than expected

I expect that when the four batteries are attached to the charging cable all four flashing green LED's will light to say that the battery is charging. Actually only three lit up and I assumed the fourth was defective. I was half way through the Amazon returns process when the fourth started flashing too. I now believe it is not defective. The instructions should say "allow 2 mins for the batteries to start flashing after you connect them to the charging cable."

Fantastic! The fact that these are 1.5V is a complete game changer, you are probably familiar with disappointment from “normal” rechargeable batteries not working for some devices. That’s usually because they are only 1.2V, these completely overcome that and work just the same as regular batteries

I love this item, I will be buying more!

Fantastic so far, no issues. Charges in a few hours

Does not support USB-C PD Power Delivery charging

As someone who's career has been working in office settings focused on records management and data entry, I quickly discovered that noise-cancelling headphones with hot-swappable batteries were a must for me. I had been using traditional rechargeables in my Bose Quiet Comfort 25's, and my recent experience had not been great, with the newest of those batteries only lasting for a little more than a day, and several of them no longer holding a charge at all. The Pale Blue Earth AAA batteries have a lifespan of around 3 of my 8-hour business days (24 hours total listening time), which is great for me. In the event that I did forget to charge them at home, the plastic travel case that holds the batteries also holds the charging cable nicely, and the batteries themselves only take about an hour to charge, so my noise-cancelling shields to save me from the constant chatter of the office environment would be back up relatively quickly. I had heard reports from people who were using these kinds of batteries in headphones where the electronics in the battery to control voltage had emitted a signal that then became audible in the headphones. In the several months that I've been using them, I have not detected this signal, however I have only been using them in the office environment where the drone of the air circulation system, and my chatty colleagues could be drowning this noise out. Beyond the longer life-span, the most drastic performance trait that I have noticed about these batteries is that when they die, they are dead. With the traditional rechargeables, my headphones would blink in and out of active noise cancelling as they died. I didn't particularly like that, so this new behaviour is something I'd mark as a plus. I'm also told that because the battery itself is tracking its lifespan, the light on the switch of the headphones won't indicate how much life is left in the batteries anymore. As the light is on the side of the headphones, and not in a place that I can see when I'm wearing it, losing this feature doesn't bother me. I imagine that as time progresses the lifespan of the batteries will take a dip, but my history with lithium ion batteries in all of the tech that I use on a regular basis is that these will probably have a much longer tail on them than traditional rechargeables.

Excellent. Charges fast, works reliably, and charges last a long time. Connectivity is easy, and the compact cord is so much more portable than the bigger plastic recharger units.

Réception en temps et en heure (Prime) Produit rangé dans une petite boîte translucide de rangement assez pratique pour le voyage. Le câble USB livré avec est de très bonne qualité, les connecteurs sont en aluminium et très robuste. Les piles sont en 1.5 volt, ça change du 1.2v des piles rechargeables classiques. Elles délivrent la bonne tension pour les appareils électroniques. La recharge se fait facilement avec le voyant vert qui clignote sur le côté + de la pile. Qd elles sont chargées, le clignotant vert reste fixe. Côté autonomie, il y a mieux c'est certain, mais vu le prix, c'est plutôt bien placé. Très bien pour alimenter des télécommandes par exemple. Attention toutefois de ne pas les utiliser avec des appareils de puissance, elles risquent de surchauffer..... Elles ne sont pas faites pour ça. Stockage dans un endroit sec et tempéré. Lors du stockage, veillez à ce qu'elles ne soient pas chargées à 100% mais plutôt a 70% .

Çok fazla şarj edilebilir pil kullandım ama bunlar gerçekten harika...

充電器を使わず四股USBケーブル直結タイプで、付属のケースに電池とケーブルも収納できるので、携帯に便利です。
