KastarCharger + 2 Battery Compatible with Sony InfoLithium L NP-F570 NP-F550 NPF330 DCR-TRV320 DCR-TRV510 DCR-TRV520 DCR-TRV525 DCR-TRV720 DCR-TRV820 DCR-TV900 PLM-100 NEX-EA50M NEX-FS100 NEX-FS700R

I use these two to power up my Chromo Inc 160 LED CI-160 dimmable LED lights. They are easily inserted and easily removed from the device. I find this method of powering up these LEDs very convenient. Can't say they last for too long, maybe close to an hour on maximum brightness. I'd say long enough. But the main weakness is the slow charging speed. It takes around 3 hours, maybe more, to fully charge with the provided charger. So you can't really count on charing one of the accumulators, while using the other. You need to make sure you have enough accumulators for the evening.

This battery charger worked very good with my Sony DCR -TRV 320

I ordered this for a buddy as he was going to pay almost $45 for a single battery for his video camera and I just could not stand to see him pay too much.He reports that the charger is BETTER QUALITY than what came with his SONY camera and the batteries ,after he charged them, show a lot more time available than his original ever gave him. He,and I,are very happy with the quality of the charger and batteries.

The batteries are great and last a long time but what I am very happy with is the charger that came with them. Now, I no longer have to charge my batteries while that are attached to the camcorder. I have had a Sony TRV 720 for 7 years( love the camcorder) and this battery upgrade is fantastic. The shipping was speedy and arrived within a few days after placing my order.

Batteries arrived as advertised but can't say much more since charger was fitted for wrong type. Carelessness. It's the little details like actually getting what you ordered that make all the difference. I'd usually say with no animosity that you get what you pay for with this kind of thing, but in this case that's only part of the problem. I assume it just got packaged at the tail end of some fourteen year old's sixteen hour work day so I won't throw a fit over the wrong piece of plastic, but consider yourselves warned..

Good Item worked as it's supposed to no problems

I ordered these for my older camcorder so I could see some of the recordings of my kids. They have worked great so far and I am pleased.

satisfaction is what I feel about delivery and quality of the charger and batteries. I've used them a couple of tims and they work fine so far. ptw
