Battery Case for Galaxy S24Ultra,Upgraded 12000mAh High Capacity Rechargeable Portable Protective Extended Charger Case Compatible with Galaxy S24 Ultra(6.8 inch) Wireless Charging Case &Carplay-Black

The battery case works well.

I love it.

Great item

Bought this after 2 other brands died, usually get about 1 year. Liked this because its smaller and not as bulky. Died exactly 60 days from purchase. Shows full charged, wont charge phone. Also a struggle to get it recharged, tried 2 different charge cords. Disappointed!!

I was so tired of having my phone's battery run down on me sorry I decided to try this to see how good it worked. It works fine I like it little on the heavy side but that's okay. I love how it charges the phone and it is fast charging Nice product I'd recommend it

This case protects my phone really well, and fits my A24+ perfectly. The case does add a significant bit of weight to the phone, but it's easy to grip and when both the case and phone are fully charged, it just about doubles the life of my battery. I haven't tried wireless charging yet.

I mean, it works. It does what it's supposed to do. But the life on it is just so short. I turned the case on around 15 or 20% and I'm down to one bar, and I'm only at 65%. The other battery case I had before would easily charge my phone from twenty percent to a hundred percent twic The other battery case I had before would easily charge my phone from 20% to a 100% twice before I'm being dead.

Charging time isnt like in the description. You can charge with it maximum one time. According to Chat Gpt S24 Ultra battery ≈ 5000 mAh (≈19.25 Wh). A 12,000 mAh power bank is rated at 3.7 V (≈44.4 Wh). After conversion losses (typically 70–85% efficient), usable energy ≈ 31–38 Wh. 31–38 Wh / 19.25 Wh ≈ 1.6–2.0 full charges → ~1.8× in real life. It is not 12000 mAh maybe 5000
