    Great battery pack. I was looking for something with a great price with about 20000mAh to 30000mAh. It didn't take long to charge the battery pack. It charges my phone quickly. I can charge my phone about 5 times from 0%. The battery pack holds a charge for a very long time.

    Over the years I've had many name brand and generic portable batteries. It seems like Energizer is a popular brand these days but I had two of them die and customer service is non existent so no warranty service. To replace it I bought one of these generic Best Buy essentials brand portable batteries and it's been really good. It's rated at 20W which means a rapid charge for your phone or other devices, and it also recharges fairly fast. It lasts a long time, I'd say longer than the similar rated Energizer 20,000 mAh portable battery. I highly recommend these Best Buy brand portable batteries.

    This charger had a lot of power, but in a smaller package. I have other chargers tgat are 20,000mAh, but they are very chunky. This one holds a charge for a long time too! That helps me because I often use it a little at a time when I'm traveling and won't want to have to keep plugging it in. The price is a great selling point as well. Definitely worth the purchase.

    Compared to the other power banks from big name brands, this power bank from Best Buy offers a similar performance at a great value! It is a little heavier than expected and easily prone to scratches but these are small complaints for an otherwise great product!
