20000mAh Small Size Unique Design 2A Fast Charger with 2-in-2-out Fast Charging Power Bank

RichRipple 20000mAh Portable Power Bank  2A Fast Charger

RichRipple Power banks battery technology:

Real Full 20000mAh Capacity.

All power banks use rechargeable batteries based around lithium technology.

Lithium-Ion and Lithium-Polymer batteries are most commonly used for power banks, but don't be surprised if other types start to hit the market before long.

Battery technology is key to many new developments: everything from mobile phones to electric vehicles, and as a result it is quite likely there will be some spin-offs into power banks.

The two technologies that are currently used have slightly different properties:

①Lithium-ion:   Lithium-Ion batteries have a higher energy density, i.e. they can store more electrical charge in a given size or volume, and are cheaper to manufacture, but they can have issues with ageing.

②Lithium-polymer :   Lithium-polymer power banks won't suffer  ageing quickly, so they are a better choice.   However they are more expensive to manufacture and as a result they may not suit all budgets.

Both forms of power banks work well, but it is a balance between cost and performance.

Smartphones are loaded with a lot of mobile applications and powered by efficient processors for fast operations.   These high performing mobile devices consume a lot of energy provided by the battery, hence the need of this reliable mobile accessory to boost the battery so as to enjoy the various features available on them.

Not only aesthetically pleasing, this 20000mah powerful power banks is also portable and pleasant to the touch.   This is the perfect travel companion alongside your smartphone, tablet or digital camera.  We are here suggest you this Lithium-polymer  Power bank, and We RichRipple has already down the cost to the lowest because we have factory to produce these power banks by ourselves.

• Rated Output Capacity: ~13000mAh / 5V )

[Important Capacity Notice]

• The Nominal Total Capacity (e.g., 10000mAh) of a power bank's internal battery cell is measured at 3.7V.
• The standard charging voltage for devices like smartphones is 5V. During discharge, a voltage conversion and boost process occurs, which involves inevitable energy loss.
• Therefore, the Actual Effective Output Capacity of a power bank is approximately 60%-70% of its Nominal Total Capacity.
• Example: For a power bank with a nominal capacity of 10000mAh, its actual available capacity for charging devices is approximately 6000-7000mAh (specific value varies bydevice and usage environment).

Notice :

The first time you receive a power bank, it is virtual power showing.   Please fully charge the power bank to 100%, and then use the power bank to the shutdown state

 (don't charge the power bank during this cycle, regardless of the number of using) until it reaches 0% blink and shut down, and then recharge the power bank to 100% again.   

Follow the above steps to use it more than 3 times.   At this time, the digital display is the most accurate!  The above is the process of power bank intelligent learning power storage.
