Great battery pack, i use it to charge my security cameras when I have bad weather for several days and my cameras need the sun, no worries now. I can charge 6 cameras and only drain the pack 15% . This is fast charging too or trickle plus i got it half off

This Battery pack is amazing!!! It has saved my life multiple times haha. I can now charge my devices anywhere and whenever I want

I bought two of these, one for my daughter who went off to college, and one for around the house. Wife likes to lounge in the back yard with her electronics, but doesn't like to run power cords. This is a perfect fix, light weight and durable with good storage. Also, good for emergency back up in car.

Great device. Fast charging anywhere. On the go without an electrical wall outlet

This battery pack is incredible! It's hard to believe that it's able to store 30,000 mAh 30W of power. I wish this kind of product was available a few years ago when I chaperoned my kid's high school trip to Florida, spending the better part of 2 days on a bus each way. I could have kept my phone, as well as the phones of 1 or 2 other chaperones. However, I'm glad to have it now so I don't have to worry about power outages, even if they last multiple days.

Plus: the amount of charge it stores Minus: its weight Nice feature the display it brings

Its safe for flight travel and suppets for multiple device charging parallel

Excellent product, holds good amount of charge. Can be used to charge multiple times.

It's much bigger (and heavier) than any other portable charger I've purchased in the past and takes longer to charge but this thing works so well. Charges our phones/tablets fast and it does not drain quickly (I absolutely love the digital display showing the remaining battery). I don't look forward to carrying it anywhere but I love using it

Works great and last for several phone charges. Love this thing.

Great fast portable power. Last for days without needing a recharge.

Great product I had to buy two honestly, was clutch on long trips

This Power Bank has everything I need to keep my devices charged in areas where ac power is virtually non-existent. I bought it after seeing that it has the necessary ports that are usable with my gear. It has plenty of charging power and very portable inside my backpack. Kudos to Energizer !

I did a charge test on this and it was at 110% cap. If you account for the average loss to heat while charging, you get full capacity for 30 dollars. Some of my anket packs score less than this.

Good powerbank and once fully charged it can charge multiple phones. Performance is good and only drawback is the device is bulky.

Definitely the heaviest and biggest power bank that I have. It feels substantial. It charges up correctly and has a lot of extra power - I think it's not only perfect for emergencies but for planned power outages. It's a good value for the price.

The capacity seems legit and charges my phone 3-4 times. However it does act iffy at low charge - it will go sometimes from 15% to 0% in a minute and once even did 40% to 0% and turned off. So a bit unreliable but otherwise good

"Excellent 30,000mAh wireless power bank, long-lasting and charges my phone super fast!"

Very happy with this product. Holds good charge! Charges my phone fast.

This thing is a beast for portable charging. It actually isn't as heavy as I thought and I've had older batteries that have less mAh but weigh more. The strap is nice and I like the screen showing the battery percentage. The only thing I feel is pointless is the flashlight, it's not strong at all and hardly lights up a dark area in front of you. But it doesn't take away from the value or use of the battery
