Can confirm that this one is genuine bought it 2 months ago, most of the batteries sold without the charger are fake even if the item is "fullfilled by amazon" stay away from them.

Thanks for your reply, that's a shame they've regressed with his new phone. I carry one of these spare batteries for my Note 4: http://www.amazon.com/Samsung-Galaxy-Battery-Charger-Replacement/dp/B00NQG2XNC and end up swapping batteries almost every day. If they didn't improve battery life, that's the main deal breaker for me.
Yeah, that looks like the Samsung Galaxy Note 4 Spare Battery Charger with OEM Replacement Battery https://www.amazon.com/dp/B00NQG2XNC/ref=cm_sw_r_cp_apa_flSZxb0PYMNWF
Although that's not exactly what I had in mind, I guess that case may work for my travel needs :)
This one right? https://www.amazon.com/Samsung-Galaxy-Battery-Charger-Replacement/dp/B00NQG2XNC
I have the same setup, plus a 10k mAh external battery pack (which ironically uses a Samsung battery), with my Note Edge. I love how I can keep them both in my purse while the battery charges.
Amazon has them for $34.99 with prime shipping http://www.amazon.com/Samsung-Galaxy-Battery-Charger-Replacement/dp/B00NQG2XNC
I know it's not the same but it's still pretty cheap and in stock.
You put the spare battery in a dock, then plug in the charger into the dock. When the battery is charged, a green light pops up. See amazon.
