Power Pack Rechargeable Battery

[11.1 VDC] 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.

[2700] This is a Great Battery Pack with even more power than the 400DR!

Awesome flash light love the rechargeable battery pack and cable

[Steel] I purchased this battery pack to replace an other one that used a rechargeable internal camera type of battery that would no longer hold a charge. To replace the battery was more than this unit cost. Love the fact this pack uses good old fashion AA batteries. Works perfect for my needs.

[Multiple] 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.

[8.65 x 4.4 x 1"] I'm a big fan of rechargeable batteries. Saves a ton of money in the long run. This charger and battery combo is perfect. I love the big LCD display. It lets you know the status of the battery and charging levels which is very helpful. I've had other chargers in the past that would just blink, or give a red/green light. Having a descriptive display is so much better, as you can gauge how much power is left or how much more needs to charge for the batteries to be ready. This is vital. It can also discharge the battery to refresh them. This is also a very handy feature to extend the life of the rechargeable batteries. It will not only charge AA but AAA batteries and I plan to get some AAA's to partner with the AA's that came with this. The batteries themselves work great and last a long time. I'm very impressed with the power and time they give. [I have received this product in exchange for my honest review]

[1.465 lb] Love cameras with extra battery power. Has 2 trays for batteries. Regular or rechargeable work. I have had it out now for a little over 3 months and it has taken pictures and videos and it is only a little over half way through the 1st tray of batteries. I love the fact that you can set it and sit back and enjoy the pictures coming in on your phone! Definitely recommended

[14 oz / 396.9 g] We originally purchased the DXA-MICRO-PRO adapter, which is the same unit except that it is powered by a 9v battery, whereas this unit is powered by a rechargeable battery with an option for an external power cord (USB). Except for how they are powered, and for the addition of the accessory plate, the units are identical. This is the unit to get if you are able to power it from USB or AC-to-USB. Otherwise, your choice is rechargeable battery (this one) or disposable battery (the other one). I hate batteries, so I got this one.

[0.185 lb] Great light but getting the rechargeable battery will make you use it so much more often.

[Yes] I love the fact that the battery is rechargeable!
