To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought the charger intended to charge my Nikon En-el18h battery. Even though I have already read the reviews that it doesn't fully charged the OEM batteries I still tried my luck. Reviews are correct, my 18b battery can't be fully charged using this charger so I plan to buy the wasabi batteries. I can't complain because I knew the risk before hand.
I usually don't leave a review within a couple weeks of purchase. However, I thought this review would help someone. The Wasabi charger has worked very good for charging my Wasabi EN-EL 18a and Nikon EN-EL 18a batteries. It has enabled me to get 9fps in my D850 . The only concern is that the initial and one subsequent charge, I can only get a 87% charge on both batteries. The charger shows 100%, however inserting the battery into the Nikon D850 shows only 87%.
I've had this product for only a few days thus far but the two times I've used it, it works great. I use the charger to charge my EN-EL18c battery to use in the Nikon camera grip. As other reviewers have noted, the calibration part of it does not register (doesn't bother me) and after I put the battery in the Nikon D850, it shows 99% charged instead of 100%. Since I don't have the Nikon charger which is in excess of 5 times more expensive, I don't know if the Nikon charger would also show 99% versus 100%. Anyhow, I usually use only Nikon products for my Nikon camera with only a few exceptions and this is one of them. I am completely satisfied and happy with this product and you will be too.
If you are looking here then you have probably already been shocked to find what Nikon wants to charge for their OEM version of this charger. I have a D500 with a Nikon grip and I use the EL18 batteries in it. Nikon wants an exorbitant amount for those batteries so I use the DSTE brand that I find here at Amazon. They work just fine. I have. No problem with them not charging to 100% and they last all day long. I have never seen the “calibrate” function work and I don’t know if that is working as it should or perhaps it does not play well with my off brand batteries. However, since they charge completely and the camera is happy with them I really don’t feel I need to complain about a non-problem. Perhaps as the batteries age the calibrate light will illuminate in the battery status and then that function will work. Not a big deal considering how much I saved. Nikon wants so much for the charger and batteries that trying the alternative options first is the only sane choice. My opinion is that this charger I know works fine with the DSTE battery and I am happy with it. It may also be fine with the Wasabi battery but they were unavailable when I purchased.
For a long time, my theory on Nikon power was to buy Nikon brand batteries and Nikon brand grips for their reliability. I saved money by buying an off-brand charger. I figured if the charger blew up, the loss was a battery, not a camera/grip. I stand corrected. One of my 2 batteries maxed out at 91%, the other at a whopping 31% after about a year of charging on the Wasabi charger. This happens every time I drained/charged the batteries. I tried calibrating. Nothing. Could both Nikon batteries be bad/failing? Possibly. Well, I bought the genuine Nikon charger for the EN-EL18, calibrated both batteries, and they now read 100% consistently. Lesson learned. Buy the reliable name brand. I would've saved myself $60 in the end plus all the frustration of the half dead "fully charged" batteries in the field.
A photo buddy told me that replacing my Nikon MH-26 charger for my D4 batteirs was going to be $300+. I said, "Not based on one model I saw on Amazon." I called Blue Nook first because the item didn't have any reviews. They were very friendly and helpful. The Wasabi charger may look slightly different, but the functionality is spot on. It charges my batteries as effectively as my original Nikon that bit the dust after a couple years. The old unit kept getting lost between charging and calibration modes and wouldn't accurately do either. Seller shipped immediately. Great find.
