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.

This is a great product

This is a great product. I use it when I go dirt biking to simultaneously charge my phone and GoPro camera. It eliminates the need to keep my keys in my vehicle's ignition while I'm taking a break, plus it's very portable.


So far i haven't encountered any problems

It takes a while to fully charge the external battery, but it works! I've charged my phone multiple times with this product. So far i haven't encountered any problems


So far this is an awesome product

So far this is an awesome product. I hope to find out its full value once I trek to Corpus Christi in a month with several electronic items.

The charge is very fast.

The charge is very fast. Charging with this unit is just as fast as plugging your phone to the outlet. This little unit packs a punch and it starts charging your phone immediately when you plug it in.


Used it to charge my phone while we were camping

Used it to charge my phone while we were camping. Worked great! Only used about half of the battery charging my phone for three days


I like this charger very much.

I like this charger very much. It is very fast to charge it and also fast to charge my i-Pad. We were out of power last night and I'm so glad I have this! I would recommend it to everybody, not just for travel, also for any time you may need power.


Got this unit quick

Got this unit quick, I started charging my iPhone 6 plus immediately and I saw results, fully recharged this unit quickly with no problems. I feel like purchasing 2 more units so I don't have to move it from one place to another.
