Macbook Full Charge Capacity Mah

The powerbank capacity was increased to 4,000 mAh for this newer model PB-96A. It is now enough to fully charge my iPhone X once for example. At 100%, the light is really bright and wouldn’t want to aim it at a person’s face/ eyes up-close, even with the diffuser on.  To test and see how long the light can be used for, I set it to 10% and went to bed at 10 PM. At 6 AM, the battery still had 75% charge. I then set it at 100% brightness and that depleted the remaining power in about 45 minutes. 5,600k matches the daytime light coming through a window. At the other end of its temperature range, 3,200k matched the interior ceiling lights at night. When unsure, I meter with my camera manual white balance and match the read or stay around it. Distance and positioning make quite a bit of difference. So experiment to get the desired look. It’s easy to use and bright enough for a street interview or vlogging at arm’s length. From a few feet away, offset to the side and at eye level or slightly above, it elevates the image quality for video calls (set from 10 to 40%, anything higher reflects off the skin and then you’d need HD foundation/ makeup). I used it for a car interior scene, table-top products photo shoots and videos as well as some creative shots with long exposures. I could not get it to overheat, even when using it at 100% for as long as possible. The aluminum heat sink just becomes slightly warm to the touch.  It comes with a phone holder, ball head on a cold shoe mount and a short tripod (wish the legs were 2-3” longer). Above all, I appreciate its compact design, intuitive controls and the small increments when adjusting the color temperature. The light is great. Having it double as a powerbank with useful mAh capacity makes it even more of a smart pick in my opinion. The attached photos on the desk show at it 10%/ 5,600k and 100%/ 5,600k.   [I have received this product in exchange for my honest review]

Great product! Did exactly as I expected. I took the old batteries from my deck post lights and conditioned them. I found out that , out of 16 - 700Mah batteries none exceeded 150 Mah. Half were less than 50 Mah at full charge.Those were made in China. I have 8 -2450 Mah IKEA batteries I conditioned next and the lowest came in at 2415 Mah at full charge. I found 4 other AAA batteries I was going to recycle because I thought they were junk and put them in to condition them. These were only 400 Mah batteries made in China. After the cycle was completed all the batteries still had a lot of use left. They all came in at 390+ Mah

Installation was simple and after charging it, the battery showed 8112 mah of battery capacity.

I purchased this for my Sound Devices 702 recorder. The battery the recorder comes with is 2,000 mAh, so this, at 6,600 mAh, is quite a bit higher capacity. While I have not yet used it extensively, I can definitively say right now that this battery is fantastic. It seems to last way longer than it should. Even after hours of recording it's still not dead. Of course, it's worth noting that this higher capacity will greatly increase charging time as well as running time. Also, the battery is physically much larger than the one that comes with the 702, so make sure that whatever case you are carrying the 702 in has room for it to protrude from the back of the recorder, as it is not flush with the unit like the stock battery. In short, it's a high capacity battery that does exactly what it's supposed to do.

This is an excellent unit to analyze the condition of your battery fleet. It provides the user with an actual mAH capacity of each battery. I mark each battery individually along with the date. When they fall below a threshold, you can retire the battery or move it to secondary backup service. Without this unit, maintaining your rechargeable batty fleet is all guesswork. Maha / Powerex provides a good 4-page instruction manual that explains the technology well.

The B&H site lists this as 6600 mAH, but it is 7800 mAH capacity - nearly 4X the standard 2200 mAH pack. I used to worry that the 2200 mAH packs would barely last long enough to record a 50-minute scene on my Sound Devices 702. With this beast, I can record continuously for 3 hours and still have plenty of reserve. I use the Dolgen charger and have fast recharge time as well.

The 3300 mAh capacity is a big improvement and is a welcomed upgrade from the earlier versions of this battery.

I have yet to see such a high tech battery charger. It has all indicators, mA, mAh, volts. The best part is, it connects through USB port. You can charge with the charger that comes with the camera, or you can charge with cellphone charger. You need to have an external charger as you do not want to risk an expensive camera with a battery charging mishaps. Nor you want the camera to sit ideal during battery charging. It is a MUST HAVE product with a Sony Alpha series camera.

I upgraded from a D7000, and am very pleased. The resolution step-up was more than sufficient for me. My D7000 batteries work in it, so with the 2 that I bought, I have more than enough. I took it on a 2-week Grand Canyon trip. I used up 2 of the ENEL15A's from the D7000, and half of one of the new ones. I took around 240 photos and a couple of video segments. My observations: - Great dynamic range - Whites will clip if the internal meter is more than halfway up the scale - I have not seen any banding in my photos - Live histogram in the viewfinder is awesome - Locking mode dial is a big help c/w the D7000 - Idiosyncratic viewscreen activation, I switched to manual - extendable viewscreen is a huge plus - Playing with all of these features and the touchscreen consumes more battery than you might expect based just on # shots - I did not try to charge it though I had a solar panel, a folding 7-watt type. It could just charge a 6000 mAh GoalZero. I couldn't charge all of the time because of raft conditions and angles / shadows. I think that the ENEL15b is probably around 6000-8000 mAh from what I have read. If wanted to seriously charge these batteries in the field, I would consider a 20 Watt or higher panel, charge a battery pack, and then transfer the charge to the camera at night. Sorry for the rambling..

I bought one of these RAV Power 20,100 mAh power banks w/AC outlet about 4 years ago and it is still going strong. Powers my video camera during shoots (8hrs dead cam, 7hrs live w/zoom), charges my laptop, and will power it while the laptop is running. These are worth full price but I caught more on sale at B&H so I bought 2 more. I have the RAV 21,000 mAH model w/AC outlet. More juice but not as reliable powering the laptop for some reason and it is a bit heavy. This brick style 20,100 mAh RAV is fairly lightweight for what it is. It does take hours to charge but it runs forever. My guess would be a slow charge provides a deeper charge.
