Charge Computer Battery Without Laptop

Without the BC-TRV you need to use your camera to charge a spare battery. So you can't use a battery and charge a battery at the same time. I've been caught out so many times when travelling. The BC-TRV solves this by giving you an off camera charging solution.... Excellent as always!!

I use this with my a6000 camera. Sony should have included this with the camera. Without it, you charge the battery inside the camera. That means you can't use your camera while the battery is charging. So get yourself at least 2 batteries and this external charger. That way you can charge one battery while still being able to use your 2nd battery in the camera.

[This review was collected as part of a promotion.] Without a doubt the X300 is the best portable speaker in its price range. The sound quality this speaker delivers is top notch. Excellent treble and mids plus liekly the best bass Ive heard from from a speaker of its size. Audio is clear both when listening to music and when using it for a hand free call. The unit itself is clean and slick and there are no visible screws of any type. All the buttons are located right on the side, and even include a battery button that when pushed will tell you its charge so there's no more guessing. Speaking of the battery it charges quite quickly using USB-C and holds about a full day of charge. Being both water and dust resistant makes this a terrific speaker for outdoor use.

[This review was collected as part of a promotion.] I can use this charging cord while I work on my computer laptop for work. It easily connects to the USB-C port on the laptop and it only took a few minutes to charge up my phone. I was pleasantly surprised because usually the computer charging cords are slower to charge than the wall outlet. But this one worked great.

Plug the battery directly into any power adapter, or a computer USB-A port to charge the battery with the provided cord.

Without a doubt, the best all in one camera. Just wish it took the bigger Sony battery.

I use it with cameras, phones, iPads, and even my laptop. Holds its charge very well. Great battery. Perfect size.

I don't use any V-Mount gear so I can't speak to that, but the plethora of ports on this thing and the wide range of USB power implementation is fantastic. The screen tells you exactly what is going on with each port when in use, and what voltage devices are requesting/receiving. It handles just about every USB power standard I know of, and claims to have quite a few safety protections for peace of mind. I use this to power my entire location recording rig: Zoom F8n Pro, a standalone stereo mic pre, even a laptop, screen, or camera if I need to. I charge the battery itself over USB C with a standard 65W laptop charger, which takes remarkably little time. Actually living the consumer DC power unification originally promised by USB C years ago is pretty wild. Clients often forget to charge their iPad/laptop/tablet/phone before sessions, often using those devices to read sheet music, and having this battery available has saved multiple recording dates and made some very happy clients. I also bought the 50Wh version which is great for travelling as light as possible for shorter gigs. Same general features and ports.

I purchased this charger for my laptop because the 45W unit that came with the device was not keeping up with charging the battery and running the laptop. Also the connection did not seem to alway work. Prior to purchasing this unit I purchased a 3rd party 45W replacement but is was not keeping up with the power requirement to charge the battery and run the laptop, plus it took too long to just charge the battery. This unit does a great job of keeping up with the power requirements. I also like the longer length of the cord to reach a power source.

The ability to charge two batteries at the same time just plugging into my laptop is great. Makes it easy to be sure you have that battery ready to go when you need it.
