Can I use my USB cable other than that came along with my NewNow® battery charger case?


NewNow® battery charger case’s efficiency?

Each NewNow power bank case loses power because of circuit resistance and voltage conversion.

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

How long will the NewNow® battery charger case lasts if it’s not in use?

Most of our power bank case’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 power bank case’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® battery charger case 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® battery charger case on board airplanes?

Yes, each NewNow power bank case 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.

Ok this case greatly surpassed what I expected!

Ok this case greatly surpassed what I expected! The power button on The back is pure genius! Was expecting a good quality case that could hold its own and what I got was a great case with a battery charger included! I use my phone constantly between facebook the web reading apps and different games and apps to keep the kids entertained and this has extended my battery by leaps and bounds. I've gone from charging four times completely to one charge! Not to leave out the fact that I have five children and giving each equal time to play and aurf accordingly is hard enough in itself! The NewNow battery case is a MUST HAVE! You will definitely kicked yourself if you don‘t do this one!


Overall a very nice product, and I highly recommend it.

This case is very nice. I have never had one of these battery cases, but it seems to protect just as well as some of the other cases that are out there, and you don't have to take out your phone out of the case in order to charge it, when you plug the case in to charge it will automatically charge your phone as well, so in the morning you're waking up with both a charged phone and a charged case, I love this thing because I like to play a lot of games and watch videos on my device, this allows me to do so and as soon as I'm getting low on power I just press the button on the back of the case and it starts charging the phone without having to plug it in. Overall a very nice product, and I highly recommend it.


This case is amazing.

This case is amazing. I am a heavy user of my phone, and often will drop the battery to below 50% before 5 pm each day, and always am charging it throughout the day. With this case, I no longer have to carry a charger everywhere that I go.


works great and very handy

Best charger ever, works great and very handy, save my life I never have to run out the battery


Definitely recommend this case!

This battery case is very well made. It is easy to get on and off of the phone. This is a great case! I would recommend this case to anyone who is looking to extend their battery life for a long night out or for just not having to plug in every night. Definitely recommend this case!


This is truly an amazing battery case!

This is truly an amazing battery case! I love everything about it, the color combination, the size, the rapid charging speed, everything! My Samsung S6 (like most other people's) is always running out of battery way too quickly so I knew I needed a battery case. I was always a bit skeptical about getting battery cases because I was afraid they would overheat/ruin my phone's battery but I am very happy to say that my NewNow case proved my skepticism wrong!


What a fantastic product!

What a fantastic product! The case arrived very well packed with a large sticker on the package bearing a scan code. I was instructed to scan the code and watch the resulting installation video. The video really simplified the phone installation process. The case is very well made and fits very precisely. While not waterproof, my S6 is very well protected - I wouldn't worry about using my phone in the rain.


This is way better than the charger case i recently had

This is way better than the charger case i recently had... I can go days without using my actual charger!


So far I am extremely satisfied with this product!

This arrived fully charged and slipped right over the 6+. It is light weight and is very simple to use. So far I am extremely satisfied with this product!


All in all every aspect exceeded my expectations

Great product works far better than one which I have previously own. Seller was very fast at getting item to me as well. All in all every aspect exceeded my expectations
