Call it what you like – a battery, a power bank, a quick charge – We like to think of it as a rescue story.
Something you hope to never use but are so grateful to have when you need it. This lithium-polymer battery has 9,000 mAh of storage capacity – more than enough to rescue you and a friend in your hour of need. And who doesn’t love a great rescue story?
A real-world explanation of Batteries and your mobile devices.
mAh stands for milliampere hour and is an expression of stored power. If you check the specifications for any of your portable electronic devices, the "size" of the battery will be referenced in mAh capacity.
Phones and Tablets come equipped with a wide range of battery sizes. The grid below is a sampling of popular devices and how many re-charges you can expect from the Lifeboat.

For all you creative thinkers, here’s another way of helping you make the right choice.
Think about a battery as a tub of cream cheese, your phone as a bagel, and your phone’s battery as the amount of cream cheese you can spread onto one bagel.
The questions then become:
How big is the cream cheese tub (the battery)
How big is the bagel (tiny phone? Or big fancy smart phone)
How much cream cheese can you put on the bagel (how big is the battery)
And finally, how many bagels can you serve up from one tub of cream cheese? (how many times can you re-charge your phone)
The chart below takes a stab at explaining things. Read along from left-to-right.
If a tub of cream cheese represents the battery and a bagel represents your phone.
Milliampere-hour. A unit of electric charge stored in a battery
An ounce of cream cheese
Amount of stored power in the eBags Lifeboat battery
How big is the tub
Micro USB Input Port
The small port used to recharge the Lifeboat
How does the tub get filled/re-filled
USB Output Port
Where you plug the charging cable in to recharge your device
The knife used to spread the cream cheese
iPhone 6S battery capacity (see above chart)
The maximum amount of cream cheese you can spread on a bagel
3.7 full re-charges for an iPhone 6S (9000mAh X 70% transfer efficiency ÷ 1715 = 3.7
How many bagels can you serve from a new tub of cream cheese
Transfer Efficiency (why only 70%)
It takes energy to transfer energy. Plan on getting 70% of the listed capacity out of the Lifeboat
How much cream cheese is left in the tub & on the knife when you give up on getting any more out of the tub
Output (in Amps)
How fast your phone can be recharged. 1.0 Amps of output charges more slowly than 2.4 Amps of output
How fast can you spread cold cream cheese (equiv. to low Amp output)? How fast can you spread warm cream cheese (equiv. to higher Amp output)
Highly efficient lamp to indicate recharging status of the Power Bank as well as available stored capacity
How much is left inside the tub?
