Pros: - Battery level display
- Huge battery capacity (I needed it daily)
- Double output USB was very useful for road trips.

Cons: - Didn't come with a user's manual, took me a while to figure out the flashlight feature
- Something happened to the charging port, it won't let me charge it anymore

Other Thoughts: I loved this product and used it all day every day. Sad it sopped working for me just after the return policy deadline :(

Pros: This is a great product which is gets the job done.

Cons: However, it took me 3 weeks since my purchase date to get my product in the mail. On the order page, it stated that it was shipped, hence why the product page states "Most customers receive within 3-5 days." However, it just means that the product has been shipped and it will take a long time for it to get to America and then will take 3-5 business days to get to your house.

Other Thoughts: I still don't know how to turn on the LED light near the USB ports due to there being no instruction manual. Other than that, this product does not need an instruction manual as it is straightforward.

Pros: Amazing!!! It kept charging two phones and 2 tablets [in "Airplane" mode] while on a cruise for over a week, and it didn't even exhaust the "first level" of its 4 power level indicators.

Cons: Heavy, especially when carrying in a purse.

The recharge/refresh time for that last of 4 levels (but what do you expect for a week of recharging 4 devices????)

NOT truly a negative!!!

Other Thoughts: I bought three, expecting much lower performance.
Bad idea!!!
Just buy one.
If it's not enough, you can get another later!

Pros: Absolutely Amazing power. I was able to charge both my Smart Phone and my iPad twice with this battery. It sure comes in handy when you don't have access to a power source. And the best price around for a comparable charger.

Cons: No instruction manual included, but not really necessary. Very self explanatory.

Other Thoughts: If you need power to recharge your devices away from home, this certainly does the trick!

Pros: This NewNow U20 20800mAh External Power Bank has had the capacity to recharge my Samsung Galaxy Note 4 four and a half times, each time from 10% to 20% charge up to 100% charge using the 2.1 amp jack in just a few hours. The half time from 15% to 35% then the U20 had run out of electrons. After one full day of charging using a normal USB 1.0 amp charger the NewNow U20 is ready to recharge my devices again. Over the past two weeks this is the first full cycle use of the NewNow U20. I suspect slightly better performance in a few more full usage cycles. The NewNow U20 is similar in size as my Note 4 and half as thick so it does not take up additional desktop space as it recharges the Note 4 laying on top of it and at just under a pound carries well in my daypack.

Cons: Non yet!

Other Thoughts: I think I have found a great quick present for those technical folks in my life needing something like this.
