As you may remember, you didn't buy the Sony multi-charger as it's only able to charge one battery at a time.
Good news : JUPIO proposes this guy, for Sony, Canon and Nikon batteries...
It can charge 3 batteries simultaneously (USB-C connector).
It can be used as a charger as well.
And it can store memory cards.
It's

No battery included in the package.

From JUPIO site:
"1.Storage
With the use of premium materials we managed to make a product that houses and protects your NP-FZ100* camera batteries, SDHC memory cards, micro SDHC cards and CFexpress Type-A cards. All in one sturdy housing.
2.Charger
But not only is the Tri-Charge a convenient storage for your NP-FZ100* batteries, it is way smarter than that because it is a fast charger as well. Just plug in the included USB-C cable and it will charge all 3 NP-FZ100* batteries simultaneously. When using a USB-C to USB-C cable in combination with a PD (Power Delivery) USB-adapter, then each of the 3 batteries is charged simultaneously with a charging current of 700mA. Each battery bay is equipped with 4 orange LED-lights, which indicates the charging status of each battery.
3.Powerbank
But the fun does not stop here, because the Jupio Pr1me Gear Tri-Charge has a third personality and that is being a powerbank. When the NP-FZ100* camera batteries are full of energy, you can use this to power all your other USB-devices like your smartphone, tablet or you name it. Connect it with the included USB-C cable and with a charging speed of 2.0A your smartphone or tablet will be recharged."
