Look that Wasabi Power's picture, the output are 4.2 V and current like 800 mA. The Wasabi battery is 7.2 V with 1.500 mAh. How do Wasabi battery can

The different models of battery have different voltages and ampacity, depending upon model. Make sure you have the exact battery for your camera. I wouldn't rely on the picture to provide the battery specifications, but rather on the text which reads: "Includes two (2) Wasabi Power batteries for LP-E8; each with 7.2V, 1500 mAh, Japanese cells " the "LP-E8" defines the model of Canon Battery that this replaces, which is a 7.2V. Check your existing Canon battery for that exact info. The 1500mAh defines how long the battery will power your camera . . . like 1 liter of gasoline will power your car for 8 miles and 4 liters of gasoline will power your car for 32 miles . . I don't see the photo referencing 4.2V. Buy on the description not the picture.

I'm not sure that I understand the question but here's what I can say. These batteries function well in my Canon 550D (T2i). They last longer than other off-brand batteries and their power metering is the same (I don't get much warning when they are about to shut off - maybe 1 min during video mode). They are completely functional. I have not used a meter to test their V & mA accuracy as it has not been a concern.

Because companies like to exaggerate in advertising, they are 40volts max, but 36V normally during most of their discharge phase. So, basically this battery can reach 40V, for about 2 seconds, but as you start to drain a battery the voltage drops and this one drops rapidly to about 36V and then hovers around 36V until it is almost drained (then goes even lower, obviously).

These batteries have a max continuous current of 4.87 amps...for 30 watts, you may want to look for one with a MCC of 10 amps (watts=amp x volts)

If your measuring the voltage of a battery (18650) with this module it becomes more tricky. The battery is only 3.7 volt. The module requires 4.5-30v supply voltage. You would have to have a separate supply to power the module with at least 4.5 volts, and then measure the battery voltage (with the third wire).If your testing voltages on a battery buy a multimeter. I use this module on a variable power supply to measure the output voltage

No, mah is only capacity, nothing about power output. I use mine all the time, no damage.

Because these batteries are not made up to the standards of the Makita battery. They have wires inside them that are soldered which is very old technology. They also lack a computer chip to communicate with the Makita charger.

watts is just amps x volts so it depends on how many amps you are drawing from the battery

The "mAh" number is "milli-ampere hours", and is an indication of the ability of the battery to deliver electricity. The higher the number, the more electricity the battery can deliver from a charge. So, if those numbers are correct, the Wasabi battery would power your camera 32% longer than the Canon battery. In comparing batteries, one, of course, needs to compare batteries of the same size and voltage for the comparison to be meaningful.

When used in series (as most battery configurations) to produce twice the voltage, available current will be the same as for one battery. Series connection - twice the voltage, no change in current. Parallel connection - twice the current, no change in voltage. BTW, the batteries that I received were 1000mAh, not 1500mAh as shown in the picture. Also, I would point out that there would be no harm in using a battery with a higher mAh rating. They would just last longer between charging cycles.

Hello Kristin, We can't speak for other sellers of this product, but if you purchase from Battery Supersite, we ship the higher capacity version of this battery which IS sealed (non-spillable) lead acid and 100% rechargeable. It has the same 12v output as the 12v 4.0ah, but is rated at a higher capacity. The capacity is listed as the "ah" rating, or amp hour rating. The amp hour rating is simply just the capacity of the battery and how much reserve power it can store. It's like the gas tank in a car; the larger the gas tank, the longer it can run. We always search the market for high quality batteries that will have a higher capacity but keep the output the same. The important thing to check is the voltage as the voltage should always be the same (ie. a 12v cannot be used where a 6 volt was used). A good example of this is the 4ah and 4.5ah battery. Nearly every battery manufacturer has updated this size battery to the 5 amp hour battery which will provide up to 20% longer runtime than the previous capacity battery. Feel free to contact us with any questions. Battery Supersite "The Amazon Battery Experts"

This PortaPow unit does NOT regulate the output to 5V. All it does is to take the combined voltage of 4 cells, and substract a diode drop (~0.6V) from it. So if you are using 1.5Vx4 alkaline cells, the USB output is around 5.4V. But if you are using 1.25Vx4 NiMH cells, then the output is only around 4.4V.

You actually need to use the Wasabi charger for the Wasabi batteries. OEM batteries will not work with the charger. I think the Wasabi batteries can work with OEM charger though. I haven't tested them yet.

The specifications on the unit give the output as 5 VDC @ 750 mA and the battery as 3.7 VDC @ 2000 mAH.

The output is listed as: 2×USB 5V 2100mA, DC 9V/12V 2000mA. mAh is commonly used to describe the total amount of energy a battery can store at one time, so that is not related to a particular voltage. The fact that it is 10000 mAh just means you can change your device more time than with a external battery of less capacity.

They are only 1.2V (all the 1.5V I found are alkaline batteries).For your purpose, I recommend you get the 1.2V rechargeable with the highest mAh. Personally, I would get these:8 pcs of Tenergy C Size 5000mAh High Capacity High Rate NiMH Rechargeable Batteries

My Wasabi says on the back "Replaces NP-Fv50". It also says "8.4V 1200mAh 10.0Wh." The Sony spec sheets for that HDR-SR12 Handycam says FP-FH60 7.2V. So I think the answer is no. This Wasabi is too powerful.

The panel does not output 5W like the specs and other reviewers suggest. The integrated *battery pack* outputs 5W, but the panel itself seems to only output in the range of 1W to 1.5W. From the specs directly from the manufacturer, the battery is 2200mah, and it takes the panel 10 hours to charge it. If you work the math out, that means it charges 220mah per hour, which would be 220ma of current @ around 5V (maybe slightly higher?), 5v * .22a = 1.1W Just because the unit has the capability to output at 5W, doesn't mean it can collect power from the sun comparable to a 5W panel.
