Hi there,

I have read several times questions about cameras with battery packs, and now I found something that might be very intresting because it can be used with almost any camera on the market.






It is called "EFFEKTA P-Bank Portable Battery Bank" and supports 2300mAh, so depending on your camera you can go several hours without the need to recharge. It supports power out from 5V to 19V at a maximum of 3.5A, and the voltage can be chosen freely.

Power in will be 19V, 3,2A so someone could think of adding a solar panel for recharging it.

more information can be found here:

(sorry only german)

The manufacotrs price is 99Ä + Tax, I found dealers selling it from 135Ä

Here is an overview PDF, also only in german:

Here is a dealers page for purchasing it in germany:

http://akkuplus.de/shop/article_3574/EFFEKTA-P-Bank---Portable-Battery-Bank.html

If I find english information I will post it here.

"Battery Bank" and supports 2300mAh, so "

... peanuts. I'll go with 5V for that available current, so MAYBE 12 watt-hours of capacity. For very small and simple cameras that's MAYBE three hours, or MAYBE half that for a typical camera (non-wifi) but most better cameras run on 12V, and I don't think you can get 2.3 Ah out of that little thing at 12V, so good luck there.

For that price ($200) you can put four (sealed), deep-cycle marine batteries in parallel and get about 100x times the capacity (at 12-14V), and it'll work just fine. The batteries are easy to find and replace, too. Use a regular car battery charger once a week, or use two at a time, and keep the other two charged to swap as needed (every few days, not every 90 minutes-- but you're not doing to do that with that $200 battery pack).

If you're going to use a battery, use the biggest one you can. Multi-hundred buck gizmos may look cute, but looks don't do much when you get down to it.

If you're just doing this every now and then, okay -- use one marine battery. It'll do the job a lot better, and cheaper, and be more reliable to boot.

Well, whenever the question came up, noone ever posted a ready to use solution. It is more easier to tell that a solution is crap than coming up with something on your own Smile

I will let you know of my experiacne Smile

Sometimes no solution is better than a bad one. Here in the States, they were arguing as recently as yesterday if it pains the condemned during the cocktail injection, and if that were the case, if it should be stopped. No doubt many different things were suggested as, eh, solutions.

Back to marine batteries... they work, have HUGE capacity relative these little device batteries that are really only good to charge your ipod, are cheap, and are very reliable. If only they could execute the condemned as well, ay?

P.S. Regular D cells have more amps that than thing. Put four or five D cells in series and you have a battery that bests that $200 thing, and only for a few dollars.

So, despite of spymasters post I will post my experiances here now.

Situation:

I am using a freshly charged cell as described above, double pack, equaling 5Ah according to the manufacors specs.

As camera I am using a Y-Cam black new model (mpeg version with firmware greater than 1.9). The cam is continously streaming at 25fps via wlan (10m from AP, 2 walls inbetween) the IR Leds are switched off.

The battery lasted 30h 20min

Then I recharged the battery and ran the same test, this time with IR Leds switched on.

The battery lasted 21h

The results ae much higher than expected, and I guess the manufactor gave an averadge power information on the battery on lifetime. According to the manufactor the battery is designed for 300 recharging cycles.

Of course spymasterflash and others will have much better, cheaper solutions - I just wonder why they don't come up with manufactors specs, where to purchase, test results reviews, but only with critics?

According to Y-Cam support the wlan module in the new models use a power management.

My next tests will be with the old model of the y-cam black.

You need to include at what voltage for that to mean anything. 5A @ 1V is 5 watts, while 5A @ 19V is 95 watts.

What is powering the access point? Another battery? If that's plugged in to the wall, what is the point of spending $300 for a battery if 10m away you have power available from the wall?

That's probably a best case (and very hard to validate). In reality, it depends. After a year Li-Ion will hold no more than some fraction of its new capacity, perhaps 80% (at best). Also, Li-Ion doesn't handle deep discharges well. If you run it empty it can damage it irreversibly. I suggest you physically remove the batteries from their control portion if you plan on storing them since it's likely the control portion will draw power from them. A stored (not connected to a power draw) Li-Ion can last a long time.

The only way I can see this as being useful is to use that $300 battery (your double pack was probably more than that) to power a camera that is attached to a laptop that is running on its own battery power. It makes little sense to power a camera with a $300 battery that has main power readily available a few steps away.

But frankly, it makes no sense to spend that kind of money for a battery.

This is common for all wifi radios. What it does it power down when not doing anything. Also, it xmits at a lower power, so range and speed are affected. I've been using wifi for several years on PDAs so I know how drastic "power management" on wifi radios is. Most people turn it off because connections drop more readily and range and speed are grossly affected (by that I mean, you may see no more than 1Mbps, and perhaps half the distance, if that, and if you've used wifi before, you already know how easily connections are dropped). Since the cam will be streaming continuously, the only power reduction possible is by reducing xmit power. Not much of a benefit (like I wrote, most will turn the PM off).

Although I already threw you a fish, I am getting in some stuff you mentioned above.

As you might have noticed the setup was for testing conditions. If I wanted to setup a camera on my desk, you can be sure that I would have used a plug. I am sure you knew that before and stated that above to point out I was dump. Otherwise I would have to think you are too dumb to see that this was just a test setup.

This shows me you did not even have a look on the specs, the battery is not Li-Ion but Li-Polymere. So you areguing not on facts but on made-up assumtions. This also gives a clue about the quality of your statements.

Ok let's come to the price:

I payed 200Ä inkl 19% VAT, that is 168,07Ä without tax.

Now let's consider that the US Dollar is extreamly weak the last weeks compared to the strong Ä, that makes european produkts expensive on the american market, and americans get the impression that the products are over expensive. The reason however is the weak dollar.

Not a made-up assumption, a fact, you can check it out here for yourself:

http://de.finance.yahoo.com/currency/convert?from=USD&to=EUR&amt=1&t=1y

So if you take an exchange rate at 1.6 for the weak US$ as we had it a few days before the price of the battery would be US$268 without tax, and it is much better for americans to buy their own products than importing from europe, after it this development goes on, americans hardly can afford good technology made in europe.

However for europeans it is a solution worth to check out and compare, after it is a plug and play solution.

Same technology. Li-Ion is the base. The "polymer" simply means it can be shaped to fit odd forms.

Here's something you could have done:

Level-one, a German company, sells cameras (and other things) in the US for much less than one can buy in Germany (it resells Asian gear, but its boxes all say printed in Germany). For example, I paid $160 US for an FCS-1060 last year (it's a bit under $200 now, delivered). Here's the first one I grabbed from a google search:

PRICE excl VAT: Ä 246.40
PRICE incl VAT: Ä 289.53
Catalogue No: FCS-1060

In dollars, that 290 E comes to 450 American. Sort of ridiculous, but if people in Europe are willing to pay that, why not. $200 US is 128 euros right now.

What if I told you German was my first language spoken? Was yours turkish? No, because I can tell you are a German just by the way you act (in this thread; I won't even go into the other threads in which you always come out swinging). Not that that's a bad thing, of course, being German (well, unless you're a former DDR'er). Come on, take another shot. I dares ya!

Nice stuff Dwayne.... In fact I have already routed customers who asked for a battery solution to this forum thread.
One of them needs a battery solution where he can place the camera in different locations every day depending on the time of the year. The price of the battery is good enough to bundle with the Y-cam. Also the duration will fit most applications.

Pity that the thread is littered with negative posts for no apparent reason. If you donít like the price or canít afford it just donít buy it.

I think that Dwayne is doing us all a favour here in testing out stuff and posting reviews. Well done Dwayne and keep up the good work!!

Are you the same guy from ycam that "quoted" me 120 pounds ($240 US) to ship a y-cam to Texas? That's on top of the 149 pounds ($300 US) for the camera itself.

Would you like Dwayne so much if he weren't shilling ycam? I think not so much.
