Battery Depleted Switch Controller

Very easy to use. One draw back is there is no on/off switch but it says battery should last 3 yrs. I have used this Controller to do time-lapse photos, long exposure and even helped with my pole photography.

Small and very lightweight. Easy to calibrate, but sometimes have to remove battery to re-calibrate. The thin controller that goes with is brilliant. And on/off switch would help. It’s tricky to figure out to push the battery to the side.

The switch was quickly adopted by the controller and was up and running in a few minutes.

Dustin Abbott on YouTube said this was on sale and I jumped on the offer purely based off the facts that it basically doubles my EOS RP’s battery life and it gave my pinky a home to grip on, greatly reducing the lens heavy nature of RF glass. As an added bonus, the Vello BG-C18 has a shutter button for vertically oriented shots; the only thing is that you’ve gotta connect a cord from the grip to the remote shutter input on the EOS RP and flip the grips switch to “on”. To me, that’s not a big deal at all. I noticed while filming myself for over an hour’s worth of footage that the grip depleted both batteries evenly. I have two Canon brand LP-e17 batteries in this grip. When I took off the grip and just put in each battery one at a time into the camera, both had the biggest section of the battery indicator depleted. I haven’t calculated how many shots would it take to deplete both batteries, but I have a feeling I shouldn’t have a problem with my casual enthusiast level of shooting. Overall, this is definitely better than paying for Canon’s cute colored grip for almost double the price!

Have used this battery pack over a few charge; use until near depleted and recharge cycles, and have found it to be as good as the original battery shipped with my X-T2. Mirrorless cameras put a high drain on the batteries since their rear display, imaging sensor and eye-level display together consume lots of power. Since this is the case, I want to carry two batteries. Personally, I rather pay the premium price for a manufacturer battery and the quality control that comes with it. This battery is worth the price. However, that's just my opinion, as always YMMV.

This is a nice compact battery booster. It will start most vehicles that haven't completed depleted their battery. My old start boost device had basically died. It wouldn't hold a charge despite being plugged in. This new booster works perfectly.

In early use of 100 test shots, here is what I have observed. If anything changes I will repost: 1) No it is not magnesium alloy... but the plastic appears durable 2) For a non-EOM product, it fits perfectly to the D850 3) All buttons tested on the grip function as intended 4) Love the ability to take a vertical shot in a more natural position minimizing body fatigue and camera shake 5) Did it seamlessly transfer from the depleted camera body battery to the Vello battery grip? SUCCESS! This was a significant concern as reviews sited that you needed to disengage the grip, reattach, and the battery would engage. I purposely had a very low battery in camera, and once depleted, it transferred seamlessly. Love double the battery life-- use live view exclusively in Landscape Photography. Here are battery transfer tips that I followed from the instructions: In the D850 Set up Menu A) Battery Type: indicate FR6 Lithium for your EN-EL15a B) Battery Order: Indicate Use camera battery first. Because I shoot primary landscape and portraits, 9 frames per/sec was not a functional requirement and not tested here. As long as the product continues to perform as is, at 25% the cost of the OEM product, its a solid investment.

Love the fact depending on the light you have to be able to charge in the unit, or put a fresh battery in and charge the depleted battery with micro usb. I definitely recomend any light that excepts the zx350 batteries especially if you can also charge the battery while still in the unit.

Given the length of time it takes to charge up a fully depleted DMW-BLK22 battery, approximately 75 minutes, this is pretty much a necessity unless you want to leave your camera plugged into an AC outlet to recharge your batteries. When I travel at the end of the day, I'll typically recharge my depleted batteries in the hotel room, while I am out doing either night street photography or just enjoying the local sights. Having a separate battery charger just makes so much more sense.

I bought this with the OMD EM1 because I always want a spare battery. It takes a couple hours to go from near depleted to full, but it has been lasting in camera better than I expected. Don't leave home without it...
