works great & compact

Works great and compact size. It doesn't weigh in much and the battery is good to hold. I haven't timed the charging speed of my s25 but it does decent job.

Not a bad portable battery for its size.
SamT Posted
The portable battery isn’t as small as I thought, but it is small enough to carry around in my backpack. The 10,000 mah capacity is good enough to charge my iPhone 13 from 20% to 90% twice, so it is great during power outages and camping. It takes about 3-4 hours to fully charge it when it is down to one light, so it is kind of slow.

Appreciate the detailed review, SamT! Sounds like it’s a solid backup for your iPhone, especially during outages and camping. Noted on the charging time—thanks for the insight!

Great option for the price.
PatrickB Posted
Overall great charger. Its not too bulky, not too heavy. Battery level indicator is handy, and it a good charge speed. Its a great choice for the price. I was able to get two full charges on galaxy s23 ultra before needing to charge it, and a full charge from 0% on my phone took about 2 hours.

Good Charging Bank
Wonderful Posted
I love this power bank. It charges my phone and iPad really quick. Holds charging for a long period. Haven’t charged it in a week and have been using it to charge my phone at least 3 times last week. Worth the price, I had other charging devices and they needed charging after 1 or 2 use .

Need for Portable Charger
AbelE Posted
Bought this as a gift for a recipient. He was very grateful since he had no way of charging his phone at certain times of the day. This charger made his devices last longer. I would recommend this item to my family and friends. It's not bulky like other ones, and it fits in your pocket.

Great charger
DoubleB Posted
This charger works great. My phone battery is awful and I'm able to charge my phone from dead a little over 2 full times. It's also not too large like some of the other chargers out there.

Worth the price so far.
AlexNY Posted
The Best Buy Essentials 10,000mAh Power Bank was on sale for a great price and I was looking for an extra power bank (you can never have too many)! I found this one online and grabbed it before they ran out. It is definitely worth having. My only issue is that it doesn't charge as quickly as I expected based on the reviews. Otherwise, it does what it says it does. That same weekend, I purchased the Belkin Power Bank at another retail site. There's not much difference between the two, but I haven't had it very long, so I will update after using again. The size is perfect for throwing in a tote, backpack, even a pocket, etc when you're on the go! Cord is long enough without being too long.

Heavy but still convenient
TUHL Posted
Decent charger, able to charge my phone and tablet at same time with expected speed. Heavy compared to some of my other chargers but compact enough to still be convenient. Does not get hot during use.

One Night Stand lol idk
MagicM Posted
It's small enough to fit anywhere. Fast-ish charging indeed, but the bank itself loses charge quickly. With increased usage and market for USB-C cords, I wish there was an additional C-port as there are connectors. But it's so good someone stole it off me!
