Switch Pro Controller Rechargeable Battery Pack

Product is much lighter than my rechargeable battery pack. I bought it because I can just switch out the batteries if it starts to run out of juice as opposed to having to recharge its battery. Maintained good connection with my Canon flashes-600 EXII-RT. It increased my flash time immensely and I feel much more confident that my flash will continue to fire with it. I have 3 600's and they all fire much better with this battery pack attached.

Great light and you can use the rechargeable battery pack.

This was exactly what I was looking for. The battery pack is rechargeable and fits in the flashlight. very easy to use.

Very nice headlamp, and it comes with a rechargeable battery pack.

Have 2 of these out, I purchased the rechargeable battery pack and made a big difference

I have had this light for a few weeks at this point and so far I love it. I got the rechargeable battery pack with it and the battery pack lightens the light up significantly. Battery lasts a long time and the light is BRIGHT! Haven’t had to use it in the weather yet but so far I am super happy with this light.

I purchased the MB-D18 Multi-Power Battery Pack after I purchased my D500. Initially I found that I was consuming rechargeable battery packs on the camera at a rapid rate when out shooting, particularly when downloading images via SnapBridge as I was shooting. The MB-D18 Battery pack gave me the flexibility of utilizing different rechargeable batteries that fit the type of photography I was involved with on different days. Utilizing the larger En-El 18c rechargeable battery packs allowed me to go longer without changing batteries at times when battery changes were not feasible. I would highly recommend the MB-D18 battery pack for any photography enthusiast who wants to be able to have greater flexibility in choosing power sources and the ability to shoot significantly longer without changing batteries!

I use this battery as a back-up to my Nikon battery EN-EL4a rechargeable Lithium-ion Battery Pack. I always use my original Nikon battery but if I am out in the field and my Nikon battery goes down after many shots, I then switch to the the Watson EN-EL4A Lithium-Ion Battery Pack as my back-up until I can re-charge the Nikon battery again at home. I find it's more economical using it that way since there is such a big price difference between the Nikon Battery and the Watson Battery. However the Watson battery is a very good battery and reliable in every way.

Awesome flash light love the rechargeable battery pack and cable

Bought this for my Tascam 100 and its amazing. This battery pack takes 6 batteries; i'm using rechargeable Energizers. With phantom power on i'm running a Senn. ME66 and a sony lav attached to the Tascam100 along with a sound devices 302 mixer with an np1 battery and i'm getting 7.5hrs on a charge. Wish I knew about this battery pack a year ago!
