    • Never deal with another dead battery
Anyone who owns a Note 20 Ultra knows that the battery drains so quickly, and it's annoying. This case is a must-have for me. I started using this case and now I can't go anywhere without it. The price and features you get are unbeatable. Other battery cases are upwards of $50+ and have fewer features. If you still need a case, this is all you need. ... show more

    • The day the battery pack died.
I found myself waking like it was Christmas morning when the man in the big blue van delivered my package. I sprang from my bed, tripped over the cat, high fived the floor with my face, then picked my jolly self up and ran, (like only I can in my overweight body) to the door. I opened the box like a gleeful Villan finally besting the good guy! I found the battery pack nestled inside like a good soilder. I on the other hand forgot the most important thing....Coffee....no ....my samsung galaxy 20 phone. Duh. I know it needed a charge, it always does with me. Thankfully when I plugged it in my heart was so full of love. Until....I came to the realization seconds later that this wasn't a birthday party to be joyful of.. but a funeral.....the day the battery pack died and never lived was the most traumatizing make beleive Christmas present I have ever witnessed in my life. RIP battery pack, that never had a chance to live....like a dream that never comes true. 😢 ... show more

    • Not very convenient, but never skips a bit to charge, while newdery often refuses to charge
This case to use the stylus is a pita to get it, and put it back, big minus! But! This case doesn't conflict with galaxy note 20 ultra like newdery does!!! Newdery refuses to charge the ohone, refuses to pick up the charge itself, often have to separate the case from the phone and charge both separately. Yes Newdery sometimes would do these kinds of kinks, way annoying! All in all, I will take this case any day over Newdery, because it works with note 20 without a shadow of conflict, charges on demand every time you press the button without a skip. As long as better alternative not available I'll take this. Newdery? Nice looks, but its a utter garbage ... show more

    • Added battery life.
I bought this with the intent to carry it regularly but it makes your phone bulky and hard to hold because it's a very smooth texture and there's nothing to grip. Along with you need to hit the power button to turn it on to charge your phone and it takes an extreme long time to charge. And to get it installed on your phone you have to be extremely careful that you don't break or damage your charging port on your phone. "All in all, it does give you a longer battery life and it will do what you brought it for to extend your phone battery life." ... show more

    • Looks great but has some unworkable inconveniences
It's got a pretty big battery inside and it charges the phone quickly. I get probably an extra several hours worth of power out of this battery. However, the downsides are pretty extreme. Firstly, the texture of the case feels nice but it's very slippery. It's very challenging to get the phone in and out of the case which wouldn't be a problem if I didn't have to do it every single time. I have plugged this case into every charging port that I have that'll fit it and it seems like my phone charges but the case doesn't. I tried pushing the button to maybe disconnect the case from the phone so it could charge itself but it still wouldn't charge. This means I would have to take my phone out of the case every night, risk dropping it in the night, and have two USB C ports by my bed. The quality feels great the case looks phenomenal but it just is not convenient in the way that I am needing. In addition to this, once the case starts to die it flashes my phone on and off over and over again as it attempts to charge and then stops and then starts and then stops. Even when it was fully charged, it seemed to be charging my phone and reconnecting every 30 seconds or so. I had to turn the charging sound off on my phone otherwise it drove me nuts. Overall, I feel like this case needed better programming to be able to charge efficiently. It needs to know when the phone needs to be charged versus the case and it needs to charge consistently like a power bank does rather than starting and stopping every 30 seconds. rather than starting and stopping every 30 seconds. ... show more

    • PEACE OF MIND
Mid day I'd have to run to my charger because my Note 20 plus was losing power. I'd plug it in and walk away to get things done and run to it if it rings. Since I got this charger I don't have to use my wall charger for a few days. This is great I just push the button on the back and my phone case starts charging. And as an added benefit, it serves as a protective case for my phone. WOW! I'm loving the convenience. ... show more
