Solar battery in general and solar battery charger in particular is about solar energy + storage this energy
Solar power is used to to produce heat and electricity. Solar battery charger concerns solar power to produce electricity stored in battery or battery systems
For solar batteries and solar battery systems is necessary to relect the demands of unstable grid energy, heavy cycling (charging and discharging) and irregular full recharging. Exists a variety of battery types fitted for above unique requirements. Considerations for choosing a battery include cost, cycle life and installation and maintenance.
Considering all that it does and its generally excellent video quality for the category and that it’s all topped off with a touchscreen, the Hero4 Silver earned our Editors’ Choice Award. Still, there are some things to know before you buy.

amazon.comDesign and features
For your money, you’ll get the camera, a waterproof housing that’s good down to 131 feet (40 meters), skeleton and touch back doors, two adhesive mounts (one flat and one curved), horizontal and vertical quick-release buckles that attach to the bottom of the camera’s housing and a three-way pivot arm, so you can mount the camera on the top, front, or side of a helmet.
A small locking plug (also included) can be used to help prevent the buckles from accidentally releasing from the mount from force or vibration. There is no charger in the box for the camera, just a Mini-USB cable for charging via computer or USB wall adapter if you have one. There is also no microSD card included for storage, so plan on getting at least one of those.
GoPro kept the basic dimensions the same as the Hero3/3+, so if you have one of those, you can still use those housings as well. What you can’t use are your old batteries.
The battery compartment was redesigned so that you just slide open a door on the bottom and load the pack into a slot. It makes swapping batteries out much easier, but it also required a new battery design. The conspiracy theorist in me says GoPro did this to force you to buy new batteries at $20 a pop (£16, AU$34) and a new external charger (though Blue Nook already has its non-OEM Wasabi packs in production).
GoPro HERO4 SILVER
Free shipping67 used from $299.00
- Built-In Touch Display: Frame your shots. Easily adjust settings. Play back videos and photos. Improved Camera Control: New dedicated button enables quick access to camera settings. Simplified menus make navigating settings easier than ever.
- Fast, Powerful Photo Capture: Captures high-quality 12MP photos at speeds of up to 30 fps.
- Built-In WiFi + Bluetooth: Delivers enhanced connectivity to the GoPro App, Smart Remote
On the left is a removable easy-to-lose cover protecting Micro-HDMI and Mini-USB ports and a microSD slot supporting cards up to 64GB. The Mini USB port is used for charging and transferring content off your microSD card, but can also be used with an optional 3.5mm stereo mic cable so you can attach an external mic. Also, next to the touchscreen is the Hero port that lets you attach GoPro’s Battery BacPac, though you’ll be blocking the screen if you do.
When not recording, the button accesses your settings menus. The menus on past models were a mess, but GoPro made things a bit easier by making everything sensitive to which mode you’re in. That means if you’re in video-capture mode and press the settings button, you’ll only get the settings options for video.
Given that there are so many resolution, frame rate and other shooting options, this cuts down significantly on the menu hunting. Plus, now that you have to go into a separate settings mode to turn on Wi-Fi it means that it won’t accidentally kick on in your bag and kill your battery.
At small screen sizes the video looks great, considering the size of the camera and sensor. The camera adjusts quickly and smoothly to exposure changes and handles fast movement (though extreme highlights will blow out) and vibration relatively well, but it’s not without its Jell-O-ey moments. There’s no option for digital image stabilization, but you could crop in when editing to help.
You can also change settings, preview and review and transfer content using GoPro’s mobile app. Just connect the Silver via Wi-Fi directly to your smartphone and you’re set. Bluetooth has been added to the Hero4 to make reconnecting faster and easier. The app can also be used to update the firmware on the camera, which is much easier than the old procedure of loading up a microSD card.
The 1.5-inch touchscreen on back can be used for changing modes and settings, too. Just swipe in from the right and select your mode. Then swipe up from the bottom and change your mode settings.
It’s way more efficient than all the button mashing required when using the buttons and small screen on front, which still isn’t lit in any way making changes at night a pain. The touchscreen lights up just fine, though, and as mentioned earlier it can be used for previewing before you shoot and for reviewing after.

So. Many. Options.
The possible resolution and frame rate combinations seem nearly endless and I’m just talking about straight-up video. Add in stills and time-lapse options and you’ll quickly find there’s no shortage of things to experiment with. I could list them all out here, but you’re better off popping over to GoPro’s specs page for the full details.
Video slider
Again, although you can record at resolutions up to 4K, the most important settings for most people will be the 1080p at 60fps, 960 at 100fps and 720p at 120fps. However, if you’re willing to drop down to 30fps for 1080p or 60fps for 720p, you’ll be able to record video and capture time-lapse photos simultaneously at intervals of 5, 10, 30 or 60 seconds.
Above is a series of sample videos shot with the Hero4 Silver set to 1080p at 60fps using GoPro’s SuperView option that digitally stretches 4:3 video so you end up capturing more of a scene, but still have a 16:9 format. It was edited and exported with the company’s free GoPro Studio software.

The bit rate at these settings is about 30Mbps, so it’s not the absolute best quality possible from the camera (you’ll have to turn on Protune for that), but more likely what you’d use for uploading to YouTube or Vimeo for sharing.
