I'm glad I purchased this charger. I usually use it at home to charge my phone instead of the wall charger. I can get 3 or more charger off of a full charge. It is a bit heavy so I might purchase a smaller/lighter one for travel.

Hi Fire, Thanks for the great feedback! We're glad the 30,000mAh power bank is serving you well at home—it’s built for extended use, and getting three or more full phone charges is right on target. While its size adds power, we understand it can feel heavy for travel. A smaller-capacity model might be a better fit for portability, and we’d be happy to help you explore options if needed. --Energizer PowerPacks Service Team

Battery can charge my watch and phone for a week. It can also charge a laptop, but it will drain battery a lot faster

Value for money. The only thing that would be nice is to get a fast plug that can charge faster. Well if you use your fast charging plug to charge the battery it does but it’s just a nice thing. Overa,, it has given me the value for money.

For at-home or at-work phone-charging-- not travel

Purchased this to charge two smartphones and for same-day, one-bag travel for days when laptop nor tablet were brought on flights. It charges one Samsung 8 four (4) times from 2% to 100% before needing to charge the bank w/ a C-to-C cord plugged into at least a 20W wall-charger; it takes 2.75 hrs to charge this phone from 2% to 100% with the energizer bank. With the 20W wall-charger, it takes 9 hrs to charge the bank from 0% to 100%, with it taking about 30min to go from 99% to 100%. While the e-display shows charging usage and tells me power remaining in the bank after charging each phone to 100%, this bank is TOO HEAVY for travel and made for home-only or work-only usage. It hurts my shoulders if carried in a slingbag, backpack, or totebag. Regardless, I am purchasing a second one for use strictly at home instead of for work, as I like the ability of having a portable charging unit that I can use in laundry room when doing housechores, for example, instead of solely near a wall-plug when needing to charge cell phones.

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.

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.
