Charging up the device takes 2 hours, but you get 15 hours of continuous recording with a full charge. The device is also voice activated, which means it automatically starts recording when it detects sound. This might concern you memory wise, but you don't have to worry about filling up the storage, because of the big 16 GB memory capacity. Even though the pen it's very light, it's very sturdy and stiff.

Buyer Guide Considerations
Quality of Recording
There are number things you need to take into consideration when getting a voice recorder. One of the biggest things is obviously the quality of the recording you don't want to get a recorder and then find out that there is a hiss or some sort of echo in the background and the noise cancellation is low-quality so your recording comes out extremely mumbled.
Memory
Another big consideration is making sure that the memory is at a minimum 4 GB for recording this would give you a minimum of 40 hours of recording time however these days the majority of voice recorders come with much more than that and much better quality with one of the recorders in the top of our list coming with 128 GB.
File System
You also want an easy to use file system you do not want your voice recorder to come with some strange file system and type that you will never be able to decrypt. The simplest is obviously MP3 however there are many other different types to keep an eye out on.
Battery Life
Another thing to keep in mind is having a minimum of 12 hours of battery life you do not want your voice recorder to stop working in mid record having you lose all of that recording time. One great feature to keep in mind is automatic voice recording and voice activated recording this is a phenomenal feature because it actually allows you to start recording when the subject enters the room or when something makes a noise.
Display
A display is also an interesting feature to have however for our purposes of a spy voice recorder you may not want to let people know that you are recording and any LED or screen would give your position away.
Micro SD
Another nice to have is a microSD slot which would allow your spy voice recorder to store much more memory.
Transfer System
Finally wrapping up having a good and easy file transfer system like a USB that is of high quality can really make getting the recordings off your device to your computer that much easier.
