Can I use my USB cable other than that came along with my NewNow external battery?


NewNow external battery’s efficiency

Each external battery loses power because of circuit resistance and voltage conversion.

As the industrial standards say, each external battery is labeled based on its raw cells capacity rather than efficiency. We follow this standard like other companies.

How long will the external battery lasts if it’s not in use?

Most of our external battery’s static power consumption is less than 100uA, which means it will take 3.5 ~20 years to use up the battery.But the chemicals inside the li-ion cells will become less active as time goes by. Most external batteries will die in two years without use.

How to extend your external battery’s life?

1. Remember to charge and recharge your battery at least once each 3-4 months.

2. Never overcharge or over-discharge your battery. You’d better keep it charged between 5% and 95%.

Can NewNow external battery be used for overseas travel?

Yes. Make sure the USB adapter you take with is compatible with the voltage of your destination country. Each adapter’s voltage input is printed on its surface.

Can I take a NewNow external battery on board airplanes?

Yes, each NewNow external battery can be taken on board airplanes safely and legally.Listed below are the related requirements.

Quoted from Federal transportation security rules (Effective January 1, 2008):Lithium ion batteries (a.k.a.: rechargeable lithium, lithium polymer, LIPO, secondary lithium).

-Passengers may carry consumer-sized lithium ion batteries [no more than 8 grams of equivalent lithium content or 100 watt hours (wh) per battery]. This size covers AA, AAA, 9-volt, cell phone, PDA, camera, camcorder, Gameboy, and standard laptop computer batteries.

-Passengers can also bring two (2) larger lithium ion batteries (more than 8 grams, up to 25 grams of equivalent lithium content per battery) in their carry-on. This size covers larger extended-life laptop batteries. Most consumer lithium ion batteries are below this size.

Big battery!!! Nice size!!!

Really great portable battery. I believe I got exactly what I paid for, a good mobile power brick with the ability to fully charge multiple devices multiple times where the ability to plug in is not an option. I would definitely recommend this product to a friend or colleague.


Love this!! Excellent buy.

Love this!! Powered my phone and tablet for 3 days without needing charging. Super easy to use, and the cord fits all my electronic devices. Excellent buy.


great charger

great charger . Can charge two devices at once . The only drawback is that it's a little bit longer than expected but that's easily overlooked .


A great product

A great product. Have used it on my iphone, ipad and kindle. It works as advertised. Charges quickly.


It's a great portable charger. I like it.

It's a great portable charger. I like it. It charges pretty quickly and I love how it has more than 1 port so I can charge my both phones at the same time. It can charge my galaxy s5 so many times.


I really like the battery pack.

I really like the battery pack. It's ridiculous size has saved by phone more than once and it has solid build quality. Obviously there are a few things on the want list, but they can be handedly over looked for the great product that it is. Unless you really need it to smart negotiate the charging rate. It has completely replaced my solar rechargeable 10400mAh battery that used to do this work and has been a great companion battery for about 2 months now. Time to get it an Aperture science sticker.


Nice looking and nice price

I just charged my samsung S5 for the first time using my power bank and i got powered up quickly and efficiently. Nice looking and nice price


Good Power Bank

Good Power Bank. I test it when I got it,the batteries nice,high power.


Highly recommend!

I can charge my n5 for about 5 times completely. Its capacity is 10400mAh. Has 1A and 2,1A charging ports. With the 2,1A port charges my phone fully in about 15-25 minutes. Highly recommend!


I was able recharge my phone and my nook while on the plane

I was able recharge my phone and my nook while on the plane. Still don't know how many charges are in this thing, but it holds plenty for an extended trip away from power.
