Power use time

Power use time namely digital camera Battery Charger use original battery can photographs number. Digital camera often can use dry cell batteries, manganese base zinc, nickel cadmium battery, nickel-metal hydride batteries, lithium ion battery and lithium battery as its power. Use the battery as a power supply, not only replace simple, and make the camera and easy to carry, flexible operation, and the battery the scope of the choice is larger.
 
Just buy back of rechargeable batteries jvc gr-dv500u charger generally very low or no electricity power, should charge before use. For charging time, depends on the charger and battery, and whether the use of voltage stability, and other factors. If is the first use of the battery, the lithium battery charge must be more than six hours of time, the nimh batteries must be more than 14 hours, or future battery life will be short. General required to pass through several times the charging/discharging process can reach the best efficiency. And the battery and residual power, try not to repeat charging, to ensure the battery life. Full of electric charge was very hot, should stay after cooling then in camera.
 
Digital cameras jvc gr-d270u charger have electricity ability, if you use a do not match the battery or do not pay attention to save, then the battery in didn't you shoot a few picture fails. The following measures can save battery usage: first, try to avoid using unnecessary zoom operation; Second, avoid frequent use flash, flash is large power consumption, we try to avoid using; Third, in the adjustment of the picture composition of best use when the viewfinder, and do not use LCD. Because most of the digital camera will open for liquid crystal display (LCD) point that consume more power, will close it can make a battery spare time two or three times growth; Fourth, use less as far as possible even pat function. Digital camera even pat function of the most built-in cache to temporarily save digital photos. If often use these cache of words, the electric power very much. Therefore, to reduce the use even the beat and the dynamic image short films function, are of great help for power saving.

Instead of mobile phone chargers head lamp

DIY LED light jvc gr-dv500u charger bulb transform old man lamp, spend minimal, the effect is very good, and continue to carry on the DIY spirit, spread, use small snail mouth bulb drawn power, transfer to standard miniUSB interface can give ordinary mobile phone batteries.

Now most of the cell phone charger jvc gr-d270u charger is actually a 5V dc output power, so long as can provide stable current power 5V can be to recharge the phone number five, and section 4 nimh battery good electricity is exactly the cell phone battery, to more than 5V should be just right. Checked on the net, does anyone really do this, he is oneself do four batteries power box, and my hand head lamp is four batteries, not just right? So immediately begin, still need a little light bulb snail mouth, then grafted in a root do miniUSB line will do.

The snail mouth posted above references miniUSB line can directly find a miniUSB this data, as long as the can, I use a broken charger jvc gr-d270 charger. Cut open, it after it 2 lines, red is positive, blue is negative, if is, must make clear data which two line is power supply, made a mistake is to be burned cell phones, meanwhile polarity is also must make right, wrong also is very dangerous, don't know is there to prevent phone circuit protection of reverse connect, be careful.

So, after two days of activities, generally a night of electricity is exhaustless head lamp, just the cell phone battery night. I use mobile phones do GPS navigation, had the recharge, the next trip, don't worry, ha ha.

Checked, like someone say this to cell phone charging, blunt discontent, even then, I feel, had this wire, emergency, direct to cell phone power supply is no problem, after all four sections BiRongLiang almost nimh batteries are cell phone batteries 2 times, can be at ease use mobile GPS. jvc gr-dv800u charger
