Rechargeable Batteries With A Usb Plug

And rechargeable through a USB.

I clearly did not understand that it didn't actually come with rechargeable C and D batteries, though instead they are adapters and you need to plug in AA rechargeable. Not sure how a AA rechargeable will be enough to power a D device....

Top quality, thin, has its own internal rechargeable battery that can be charged by USB or power plug, all included. Touch on and off , perfect light, no flicker. Big enough for one sheet of 35mm, 120, 4x5” or 8x10” neg.

It works perfectly! No need for batteries as it is rechargeable and it last for 7-8 hours but it can run forever if you plug an external battery on the trasmitter (mike) during the use. No problem at all. I Love it!!!

Quality rechargeable batteries.

This is my first time purchasing rechargeable Lithium Ion batteries with a built-in USB charging port. That's a very convenient way to charge the battery especially if you forgot the adapter at home.

First of all, I'm not sure why Logitech ever discontinued this excellent keyboard. It was inexpensive for my budget, and had the PERFECT feel. I cannot stand the insane loudness of mechanical keyboards. This keyboard hits the sweet spot as it is not too loud or too quiet. The width of the keyboard is just perfect, as I sit in a recliner in front of a big TV, and have no issues with anything. Unlike someone below complaining about the numeric keypad on the right..... that is standard on almost every keyboard. No one uses the top row, are you kidding me? It's too easy to use your right hand to easily hit every number and math symbol. Top row numbers are useless unless you're playing a game. They take longer to press because they are spaced out about 10 inches!!! No thanks! Now, I will miss this keyboard greatly, and sadly I spilled stuff on mine and two of the buttons now stick forever and I kind of broke them when trying to clean it, so I will be buying another keyboard. But the other fantastic feature of this keyboard that is hard to find anywhere is the USB rechargeable feature. This allows me to not have to worry about changing batteries all the time! I don't even like changing rechargeable batteries because it's just annoying. It's so much simpler to be able to charge the keyboard with a USB cable and get several days or weeks of life out of one charge, depending on usage. RIP, K800. You will be missed.

These rechargeable batteries are the way of the future! I have not bought batteries since I started buy coast flashlights. I recharge them from any usb port which is super handy. I also notices that the rechargeable batteries discharge faster and are brighter all together and because I only have to buy them once i don't care when they run out

These batteries are game changers, individual USB C charging is one of the best ideas I have seen in a long time. No more bulky chargers or old style rechargeable AAA/AA that will not power most devices due to a lower voltage/current limitation on the old style rechargeable. As a A/V Installation Technician I have many tools with regular battery requirements. Multi-meter, network tester, cable toner, signal generator, laser level, flashlights etc...I am now saving a lot in the cost of disposables without impacting my tool use, great job Coast! and top notch customer service.

These are the best rechargeable batteries I've ever used.
