SMALLRIG 2520mAh Replacement USB-C Battery for Panasonic DMW-BLK22, 2.5H Fully Charged, for Panasonic LUMIX GH5 / S5, for LUMIX G5 II, S5 IIX, GH7, GH6, S9, G9 II

Have used this batter for quite some time now and no storage degradation. Quick charge and consistent power to camera. Charge last long than needed and quality is very good. For the price and charge convenience, this battery is a good buy.

I find the colors on these batteries very helpful to remember which batteries i have already used. I wish they came in more colors as i can sometimes go through 4-5 in a big shooting day!

Why buy anything else? Charges fast, I can charge in my camera bag off a little battery pack. Super visible, very good. Bought multiples after trying one

Thinking it would be a goofy gimmick, it is crazy convenient to have a usb-c port on the battery. Most chargers (that you'd willingly travel with you) come in pairs. When your charger is full, this feature is amazing. I love the colors and capacity of SmallRig's batteries. If you're considering an extra battery, just get it. And get these!

I bought a Lumix S1RII that I love but has semi poor battery life so I wanted a spare battery. I didn't want to pay $$ for the original battery as it's crazy expensive. This Smallrig battery has a great price, I really like that it has a built-in USB port you can charge directly to the battery. Long story short, the battery works very well but, in my case it definitely does not last as long as the original Panasonic battery. It also charges faster than the original battery. I noticed the battery life is not as good as the Panasonic battery, especially if you leave the battery in the camera it definitely drains much faster than the original. That said, for the price and for a second battery, it seems about perfect. However, if you want the longest battery life it seems it does NOT last as long as the original battery which is way way more expensive. This doesn't matter so much, but I love the Orange color.. :) Very good value, a "good battery"....not quite as good as the OEM battery!

Works well. Charges fast with USB. Not meant for a regular charger, it will charge very slow.

These batteries have saved me lots of headache trying to recharge my batteries from inside the camera, they seem to last even longer than the standard Panasonic batteries, and cheaper. Being able to charge these via usb-c is a game changer

I was doing extended traveling overseas for 2 months, so I was very keen a keeping my entire travel USB-C compatible. It was either this, or an external USB-C input charger. I’ll save you the trouble, buy this instead. The space savings alone made it worth it. Tha said, I wish this supported fast charging, since the purpose of having this is mobility and portability.

Batterie SMALLRIG DMW-BLK22 utilisée en complément de l’originale, et rien à dire. Elle fonctionne parfaitement, se charge normalement et offre une autonomie comparable à la batterie d’origine. Mention spéciale pour le port usbc pour faciliter la charge

Buena batería, dura bastante y carga rápido. Usada en una Lumix S9, volvería a comprarla, y tal vez lo haga cuando lo necesite.

Great functionality, the USB C direct charging makes life easier considering Panasonic doesn't provide a charger anymore with their cameras. Battery life is as good as OEM and charges fairly quickly. Pricing is good compared to OEM batteries.

The NEEWER S5II/S5 replacement battery (DMW-BLK22) works perfectly with my Panasonic Lumix GH6. It delivers solid performance, lasts well, and can conveniently be charged from a power bank anytime — super handy for travel and outdoor shooting. Exactly what I needed. Highly recommended!
