Customer Ratings & Reviews

I bought three of these for my three sisters. Only one worked and thankfully for the sis that needed the most. The ones that didn't work seemed like they were charging (started at 3 out of four dots) but even after multiple tries, it didn't charges my iphone. The one that worked needed to be charged but functioned properly. Charged a bit slower than I hoped. Getting replacement so hoping they're not defective either.

This charging pack has enough power to charge my iPhone completely. Awesome product for someone who does not have access to a wall charger. Also great quality for the price.

Nice to have a second battery finally. This works just like the first one that came with my kit. No issues, and nice to be able to change out real quick when I am outside.

I'm constantly forgetting to charge my phone. I keep this in my car charged and once I get out, throw it in my purse with my phone and have a complete charge in no time.

This is a great product. I'd had experience with much smaller devices that did similar things but was looking for something much bigger and this on sale was a no-brainer.

the first one i purchased was defective and had to take it back and exchanged for one that worked.....

The Mophie Powersation 4000 external battery is a good and functional device to power my USB devices. While I do wish that it was not so bulky, it is an excellent device that can be used to charge my phones on-the-go.

Bought this Mophie after seeing it advertised in the Best Buy website. After the initial charge it has held its charge very well and it has performed as advertised.

Mophie - Powerstation 4000 Rechargeable External Battery is great product. I used it when I went to San Jose. It's last long more than 4 hours for charging. I loved it.

Picked this up while on vacation in NYC. Taking so many pics and using gps to get around was killing my battery. The mophie when fully charged gives my cell phone 2-3 complete charges.

Very useful for when my phone is near the end of charge I can charge it whether it is on or off. Can still use it when it is recharging.

Found this online on sale and bought two. Have used it numerous times to charge cell phone and other devices. Typically will get 2-3 charges before needing to recharge.

The Power Station 4000 performs as advertised. Just be sure to use an iPad wall adapter for faster charging. An iPhone adapter will work, but it takes noticeably longer.

I got this on sale for $10 and gave as gifts for Christmas. My family has been impressed with how quickly it charges their phones compared to other external batteries.

I bought this for my iPhone 5 when I take the bus to and from work but it doesn't just charge my iPhone but also my bluetooth earphones and anything that can be connected with a USB.

This little charger is compact and practical. It has its own built in charging cables for a less cumbersome experience. Wouldn't change anything about this product.

Bought this for my son and it does a great job of charging electronics quickly and is able to charge several devices on just one charge. Highly recommend this item.

I keep it charged up in my purse in case I ever need to charge my phone when I don't have access to a wall outlet. I e charged my phone at least twice on one charge. Works great!

I got this and it's great charging my iPhone 7 Plus and it charged pretty fast. It has circuit protector and they sell this at the Apple store...Apple certified.

I've bought this brand of charger from Mophie before and I never had any problems compared to many other brands that I hear about not being able to hold a charge.
