Question: Is this unit capable of recording while charging? If so, has anybody used an external battery pack with this?
Document: Great HD camera, but you can NOT charge it while it's in use. Once you plug it in the video stops recording and it goes into charge/download mode. Sucks when you dash mount it and travel long distances. Battery just doesn't last long enough for long recording sessions.
I bought one to wear on my clothing to capture video of my kids playing. The clip is strong and the camera is super easy to use. I used it this winter to video snowball fights and sled riding. I've used it so much, friends have bought the same unit after watching my videos.
I've used this product for about a month now. It doesn't record audio on 1/3rd of the videos i've taken. Perhaps it has something to do with the camera going to &#34;sleep&#34; and when i spam the record button to try and wake it the heck up to record my action shots. Takes about 5-8 of hitting the record button on the remote, to wake up and start recording. I'm not loving this thing.
Just got this product yesterday, picture looks pretty good. So, I used it driving to work this morning and when I got to work I checked the video and I realized that I had it upside down when recording. So, now I'm in the process of rotating the view and converting the mov file to an mpeg. I can give a better review when I use it more in the next 2 weeks but quality wise its a solid product.
Great value and quality feel to the unit with outstanding camcorder unctions and options to video at different defs etc. Looks cool as well :)
Easy to use, good battery life. Comes with so many attachments which alone make this purchase satisfying. But it also captures great footage while mountain biking on rough terrain. Very impressed.
I did a ton of research prior to purchasing this item. I have had it now for a year, and during that time it has slowly stopped holding a charge. It started out holding a good 3 hour charge, then went to 1.5, then 1, and so on. I am now lucky to get 30 minutes from one charge. Another interesting issue is that I will charge this unit overnight and it STILL is not fully charged by the morning.
The Muvi truly is an amazing little camcorder with the capability of recording in 1080P for over three hours with the recommended 32 GB SanDisk MicroSDHC Class 10 Memory Card that Amazon recommends as part of the bundle. It comes with a plethora of mounts (no suction mount, though). The ones I use the most are the dashboard mount and the headband mount.
My unit stopped working, I bought it 3 months ago and never even took it outside. I emailed customer support, no answer. There's just non-committal, "we'll aim to reply to further technical support enquiries within 24 hours". Well, it's been more than that and I'm still waiting. There are no phone numbers to call. Not even a troubleshooting guide (just a short list of FAQ).
This camera has much better quality than most camera's I have seen that cost more than it. The time lapse function is really fun to mess around with. It does not have very loud sound but if you are in a quiet room you can hear it very well.It takes a while to charge but it has a long battery life.
Answer: 1) no.  2) I have used a battery pack and it charges the camera's battery just fine 1-4 hours and during this downtime you cannot use the camera till it is finished charging. After my purchase I contacted the company and asked several questions also made a few recommendations as a customer that could make the camera more user friendly etc.  No response! I am currently researching for another camera that will fit my needs and use this one as a backup or spare.
