Mcoplus EOS-800D Vertical Multi-Function Replacement Battery Grip for EOS Rebel 800D/T7i/X9i/77D/9000D

Good item.But, not in conneting cable

Utilisation sur un EOS77D.Aucun problème de fonctionnement.

This product worked 100% with my Canon 77D. Other online products are known to cause the camera to not recognize the battery as an original Canon battery and display warning errors. I installed two Neewer LP-E17 replacement batteries (recognized as DR-E18 with or without the vertical grip). While they function fine, the camera does not provide recharge performance. However, this is a battery issue and nothing to do with the vertical grip battery connector. When I install the original Canon LP-E17 on the vertical grip battery compartment, it works perfectly and shows the recharging performance measurement correctly.The battery fitment is very snug and the holding clip works perfectly. Make sure that you tighten the grip's installation knob to avoid any faulty contact issues since your power is running through the vertical grip.Installation was straight forward and very easy. Note that the vertical grip has a battery cover storage compartment and you can store it there to avoid loosing it. Ergonomically, I like the feel of the grip and the rubberized handle makes it very comfortable.I powered on the camera with both Neewer batteries and took about 500 pics (mostly without using the LCD rear display) and my battery remaining capacity still showed full. I was able to use the grip's dual battery without switching the vertical grip power button to the "On" position, so I am not sure what this button does or doesn't do.The build quality is good and the grip pattern matches that of the camera. You wouldn't know this not an OEM add-on from the looks of it.I would highly recommend anyone looking to add a vertical grip to extend the battery life of the Canon 77D. It is fully compatible and works excellent.

The light itself works well - until it doesn't. The power pack that came with it was not a problem, until it shorted out and shorted out another DC plug I connected to it. Obviously a low-cost option will run electrical risks - but the timing of this couldn't have been worse. I haven't made my mind up as to what to do with it as yet - either I invest in batteries to charge and power it with or I chuck it in the bin.

I bought the 77D mid-2017 or so and at that time there were no battery grips available, first- or third-party. Fast forward to March 2018 and I looked again and there seems to be two types of Chinese third-party grips available. The version sold by Neewer, and one or two others, has a little battery tray that slides out from the right (looking at it from the viewfinder side). The other version, by a company called "Mcoplus" has a door on the rear side that releases down and the two batteries slot in side by side using a mechanism similar to the battery compartment in the camera body itself. That version is a bit more expensive, but I went with that because the little "twist tab" that releases the battery tray on the Neewer version (from the picture anyway, I haven't seen one in person) seems a little too delicate. Also, in my case, I have a Peak Design hand strap on the right side of the camera body so it seemed like it would be a hassle to access the pull out tray.All third party versions have a second shutter release on the grip, but it will only work if you use a small cable to connect the grip to the camera's shutter release connection. This is apparently because for whatever reason Canon did not include in the interior of the battery compartment any connections for anything other than power, such as for shutter release. The little cable is not so bad, and at least in my particular case, I don't think I would ever use the second button except on a tripod anyway. The 77D does have a removable battery compartment cover, so if they never planned on offering a first party battery grip, at least they left it open for third-party solutions.All the Chinese third-party versions are available on Amazon. I didn't conduct an exhaustive search so it is possible that Canon has a first-party version, but I don't think they do. The "Mcoplus" version I got seems sturdy enough, and quickly and easily attached to the 77D. It makes the relatively small 77D a little more solid and substantial in the hand. Inserting the batteries into the grip is a wee bit tight, but I'm not so sure that is a bad thing. I like that the door flips down and the battery slots are readily accessible. I haven't had any issue mixing my one OEM Canon battery with a third party version. So far there does not appear to be any excessive play on the flip down door. The unit screws onto the base of the 77D body tightly, and the Peak Design base plate I have screws solidly into the bottom of the battery grip. It powers up so far with no problems. I've never used an original Canon battery grip, but I assume that all of these knockoffs are not as well built as the Canon version, but since there is no Canon version, it doesn't really matter. Also, I would assume that if Canon did offer a version, it would be 4 or 5 or six times the price, so there is that. The second shutter button seems relatively sound, the battery door seems to close solidly, and the grip fit into the camera body battery compartment tight enough. At this price point if it lasts a few years that would be great. I have not seen or used the other version, so I can't opine about how it compares to the version I ordered. Hope this helps any 77D owners out there. BTW I have no connection to any of these sellers, and I did not get anything free for "my honest opinion." I was a little nervous purchasing this version without any reviews, but I preferred the "flippy door" to the pull out tray, so I thought I would take a chance and it seemed to work out.
