20,000 mAh Powerbank and Why It’s Essential to Own One

We live in an age of portable electronics, which also means we live in an age that demands the convenience of powerbanks that can keep our multiple devices charged and ready for action. And while smaller powerbanks with 5,000 mAh and 10,000 mAh capacities, a 20,000 mAh powerbank will last you longer and charge your devices multiple times.

But with so many sizes and options on the market, choosing the right 20,000 mAh powerbank for your lifestyle can pose a daunting challenge. The best place to begin is understanding the science behind the mAh acronym itself

Understanding mAh

The standard unit of measure when sizing portable powerbanks is known as milliamp Hour, or mAh, which refers to the energy capacity of a battery over time. The greater the mAh the higher the capacity and the more hours that the powerbank can be used before it discharges all its power. The math is fairly simple: divide the capacity of your powerbank by the draw of your device to calculate the number of hours of charging time available. A 20,000 mAh powerbank, for example, could theoretically power a smartphone that draws 100 mA for 200 hours.

Of course, any powerbank does loose charge over time and there also loss due to inefficiencies associated with then type and condition of the charging cable you are using as well as the capacity and of the battery being charged, but you get the picture.

Why a 20,000 mAh powerbank?

The benefits of choosing a 20,000 mAh powerbank are numerous, so here are some of the key benefits that comes with choosing more capacity when you have a choice:

Higher capacity means that you can charge more devices more often. There is nothing more frustrating than having to constantly be recharging the device that you want to use to recharge your devices. A 20,000 mAh powerbank can literally go days between recharges, which means that it is more readily available for action than its smaller 5,000 or 10,000 mAh cousins, which drain more quickly and have to be recharged more often.

Easier to carry than multiple smaller units which take up more space to deliver the same amount of charge capacity. A good quality 20,000 mAh powerbank weighs in at around 4 ounces, which is the same or less than an average 10,000 mAh unit. So why carry 2 units at double the weight just to get the same charging capacity as a single 20,000 mAh powerbank can deliver?

This makes a 20,000 mAh powerbank the perfect choice for travelers, hikers, and outdoor adventurers. Besides the ubiquitous smartphone, a standard day- or backpack contains more than simply a change of clothes, some basic toiletries, and medical supplies, and a map. It’s also likely to contain a digital camera, laptop computer, some portable travel speakers, and perhaps an eBook for reading on long bus or train journeys. The common denominator of all these modern accessories: they need to be recharged, and a 20,000 mAh powerbank is exactly the portable workhorse you need to keep your devices ready for that once-in-a-lifetime photograph or video.

Capacity and Portability Make Ideal and High-Performance

A 20,000 mAh powerbank offers the capacity and portability that makes it ideal for the high-performance professional. Photographers, real estate agents, tradesmen, and small business owners rely on their electronic devices heavily while moving between jobs or tasks. Knowing that they have power readily available when they need it is one less thing to think about during a hectic day. Small enough to slip into your pocket or briefcase, a 20,000 mAh powerbank is the perfect safeguard, too, when you know that today’s client presentation is crucial to next quarter results. Simply plug in your laptop knowing that your slide deck will never fade to black unless you want it to.

And when you need some downtime after closing the big deal, a 20,000 mAh powerbank delivers the charging punch that gamers demand. Mobile games are a notorious drain on a smartphone charge, but you never have the fear of missing out on making it to the next level knowing that your powerbank is charged and waiting in your backpack or suitcase.

And finally, a 20,000 mAh powerbank is a perfect safety feature. Keeping one charged in your glove compartment or tucked in your purse means that you never have to worry about falling out of touch due to dead or dying cellphones. A broken-down car or suspicious stranger is scary enough to deal with but there is never any reason to be out of touch due to a dead battery.

Key Features

Not all 20,000 mAh powerbanks are created equal. Here are some of the key features to look for when purchasing this essential tech-support item:

Quick-charge, USB ports are essential in today’s fast-paced world

Transportation Security Administration (TSA) airline-approved means that you never have to worry that your charger won’t make it through a baggage check when you need it most

Dual outputs so that you can charge two devices at once or share with a friend

LED display so you know when the unit needs to be recharged and never got caught without the charge you need when you need it

Durability so that your 20,000 mAh powerbank can keep up with your lifestyle, whether that means working the boardroom or hiking the backcountry.

Final Thoughts

Electronic devices are a huge part of modern life. 88 percent of Americans own at least one laptop while 75 percent report owning one or more smartphones. Devices help us work, stay connected to family and friends, capture memories, and keep us safe. A 20,000 mAh powerbank is a reliable engine that keeps all these devices charged and ready for action when and where you need it.

Adding a 20,000 mAh powerbank to your desk, car, or backpack not only makes sense, but it is also an essential accessory to living a full, rich life in our intricately and wonderfully wired world.
