How long does it take to charge a Canon camera's battery?
Batteries are measured as having different energy levels, which allow the batteries to last longer or shorter than the other guys. With digital SLR cameras, I have generally gotten around a thousand shots per battery charge. With this in mind, I usually drag around two spares at any given time so I don’t run out of juice. I always have a battery in the charger and when I run out of one, I replace that one with a freshly charged battery. I’ve never timed the actual event of charging a battery, given that I have a slew of spares available at any given moment. I think my camera bag has 6 batteries for my Canon 50D and 40D cameras. I try to buy batteries rated at 2000 Ahn or better, so they will last longer per charge.
I forgot my canon 5d mark ii battery charger, can I use my laptop to charge battery?
Why do you have a professional level camera if you don't even understand that no DSLR can be charged through a connection to a computer?
Is the Pisen LP-e6 battery compatible with the Canon battery charger?
I've heard stories about non-canon batteries frying within minutes of charging on the default canon charger... Does anyone know from experience if the pisen lp-e6 battery is in fact compatible with the Canon charger? I don't wanna fry my battery... :( Please only comment if you know FOR SURE (e.g. from direct experience) or you are very confident in your answer (e.g. you are a semi-pro/pro photographer who knows almost everything about DSLRs. BTW my camera is the 60D, if that makes a difference. Thanks!
Why can't you charge a DSLR Camera battery via a USB port?
Most digital cameras run from large batteries at higher voltages… USB has not offered a very good charging option compared to the various others. But this is slowly changing as USB becomes ubiquitous and grows up a bit.Here's the new Panasonic DMC-G9, a fairly high end Micro Four-thirds camera. And its one of the first I've heard of that actually does support USB charging. The standard battery is rated at 7.2V, 1860mAh, 14Wh. So expect it to take 3.5–4.0 hours to charge from a USB 3.1 data port, a bit over two hours from a USB Battery Charging port. That is extra circuitry in the camera, extra heat as well, given the need for a boost converter.And actually, the best part of the USB power connection for a serious user isn't the battery charging at all. Rather, it's the ability to run the camera from a USB power supply. That could be anything from a wall wart to a 15000 mAh power brick. And given that this camera uses a peak of about 1A on USB, on a standard Battery Charging port, the battery will get some charge.The other reason USB charging on a serious camera is unusual is that it's not that useful to an advanced user. I can't use my camera while it's plugged in and charging — until recently enough, USB charging wasn't powerful enough to run the camera, and even then, it's some kind of a tether, not ideal for anything other than maybe video or studio work from a big tripod. Batteries are inherently replaceable, so why not charge one of two while using a few others… my trusty Watson charger has travelled the world with me!With the advent of USB Type C and USB Power Delivery, I think USB charging will be far more common in DSLRs, mirrorless, and other serious cameras. You will get fast charging, higher currents and voltages, etc.
Can I charge my DSLR battery with a usb cable?
Probably not.Most DSLRs plug into USB for data transfer only, not charging.In order to charge your DSLR battery, you need a battery charger. It’s quite common for digital cameras to not have the charging circuit contained in the camera at all, particularly DSLRs.Part of this is simple math: the original USB Type A port could provide 500mA of current at +5V. For a pro DSLR, you probably have a battery that’s 7.2V or so, dual-cell Li-ion, and with a capacity of 1500–2000mAhr, as with the battery I have here for my Canon 6D.First problem is the voltage. You can’t charge a battery with a voltage below that of the battery. So in order to charge from a +5V power source like USB, you have to “step up” the +5V to maybe 8–9V, depending on what the actual peak voltage is on that battery. When you boost voltage, you drop current. So that 500mA becomes around 250mA, given boost regulator efficiencies and all.This particular battery is rated at 1800mAh, which means, at 250mA, it’s going take at least 7.2 hours to charge. That’s pretty unacceptable to most photographers. Now of course, a charger that can use USB 2.0 power delivery can get 1.5A out of a charging port, lowering that to around 2.4 hours. But they don’t change pro battery form factors very often .. most of these have been around before USB could do this.Also, it’s pretty common to want to use your camera while you’re charging a battery. So most photographers are going to have an external charger or three. When I’m travelling, I can leave a pair of batteries on my Watson charger and bring another pair with me, then swap when I stop in for a minute. Works great. So I suppose that many manufacturers consider in-camera charging kind of pointless. It’s extra parts count, extra size, extra heat to deal with during charging, etc. And they only design that charger once and cover a dozen models, versus having to work out that charging circuit in every new camera.Not all cameras, though. Consumer point & shoot cameras often do charge from USB. They probably also use a single 3.6V Li-ion battery, which can be charged directly from USB without the need for power conversion hardware (obviously, it still needs a charging circuit). Plenty of consumers don’t swap batteries, and they’re ultimately saving some money per camera with the in-camera charger done that way.
Can a USB cable be used to charge the Canon 450D camera's battery?
No not directly as the USB only provides 5 volts and the LP-E5 Li-Ion battery used in the 450D requires 7.4 volts. There used to be a USB charger that required 2 USB ports that could charge these batteries, see:Amazon.co.uk: Camera & Photobut it’s just as cheap to purchase a mains operated one, which would probably charge the batteries much faster than the USB version.
How can I use a selfie stick with an iPhone 5s?
This is not a 5S specific question. Most iPhones and sticks will behave similarly.There are two things you should care about.how to hold your phone with the stickhow to trigger the photo or the videoHolding the phoneThe sticks mechanics are usually quite good, you can resize them to hold any sized phone (well within some limits). The phone might be too heavy for the stick or the mechanism. Better try this first.Triggering the photoThere are at least 4 types of trigger solutions, which might be compatible with the iPhone:Trigger button, this is a Bluetooth device simulating a buttonpress (probably the best solution, if it works) and this triggers the photo or video. Just like pressing the volume button of the phone.Bluetooth communicating with an app (not too good, you need to start up their app to make and store the photo)mechanical trigger connection with the iPhone (not a nice solution), for example plugging in a cable into the phone.no connection, you need to use a built in timer to trigger the photo (not very handy)PairingWhen using a Bluetooth solution, you should pair the selfie trigger button with your phone first. (This Bluetooth trigger button can be built into the stick, or can be totally separate.) Then your phone and the trigger button also "remembers" this pairing, and you do not need to pair them again. Such trigger buttons might be paired usually with one phone only, so you need to break this pairing before pairing it with a different phone.The triggering (or pairing) might give you problems. You better try it first before buying.Sadly this is not very straightforward, I just returned two Bluetooth triggered sticks, because they would not pair with my phone.NoteYou should also care to switch off the Bluetooth trigger when not in use, these devices usually use tiny batteries, which discharge quite fast (within days) when kept turned on. You should buy some intelligent ones, which at least have a small led showing that they still have some charge.
