Customer Ratings & Reviews

Takes time to charge, but once its fully charged, it holds it well, and can definitely handle charging devices on the go. Used for a multi-day convention and never once ran out of power when I needed it thanks to this!

Got a 10000 Energizer last year and it has been a real work horse and continues to hold its charge. I needed more battery then the 10000 and purchased this model for 10 off the grid trip and it kept all my devices charged and I still came back home with 24 percent left.

Checked the airlines websites, this device is too large to be carried on the airlines...you may be able to get away with it but if questioned by TSA you may also need to throw it away if you intended to purchase this unit for travel. Suggest the lower capacity 20K unit which can be used for air travel.

This unit is heavy, I would compare it to a 3 pound weight. I owned this about a week. When it came in the box it was at 77%. I have not allowed it to drop below 50%. It take a while for it to recharge. So make sure you charge at night and just walk away. I did notice when I went to unplug it the unit it had cut off and only reached 99%. I just plugged my phone in to write this post and look on the net about 20 minutes later it’s at 97%.

It wasn’t charged to 100 when I received it and I was unaware that I would have to buy an adapter to charge it in the future, but overall, it does exactly what I need and I am grateful for it.

This works really well with a very long battery life and not a crazy amount of charging. Some airlines will accept it, however, some will take it away. If you are buying for travel get the smaller option.

Its as intended, has a large capicity which is nice. Then i was able to charge my phone with it for a week straight while camping. Only downside is the price, its in a reasonable spot but still seems like a bit much. Other then that 5 stars

Too heavy and will only last for 2 days even if I am just charging for a few hours.

Best portable charger ever !! Don’t hesitate and buy this amazing Energizer 30000 great buy.

A little heavy but it charges very fast. I would buy it again

The product is easy to use. I can carry it around in my personal bag while I travel. It charges my battery and tablet fast and it is durable. This is best purchased I have made for the price of the charger.

It’s really worth it I am so happy to buy this product battery last long for long time and it charge quickly.

Great power bank! I used this for a camping trip and it kept my phone charged for all 4 days.

took a while to charge up to 100 but otherwise no complaints.

Great choice, allows more freedom to move around and longer use time when away from a fixed power source

This power bank has been working very well for me charging my iPhone and iWatch!

This battery lasts a tremendously long time! Greatly exceeds my expectations!

Works awesome!! Great product and very good price.

It seems substantial but honestly, I haven’t had to use it yet.

Works great. Can completely charge an iPhone 11 Pro with just 15% of the battery pack. The unit is heavier than I expected. I would have ordered a smaller one if I knew it was so heavy.
