I’m going to tell you my lovely days in Lisbon, which was the capital of an empire. All lisboa remembers his glorious padado. Like when sailors came out to discover and conquer lands on the other side of the world.
You see old faded tiles on their facades. Peeling walls and stone streets lined with old trams. No great luxuries or European stores are sought in this city, although they do. What is sought and found is a melancholic beauty, art, imperfection and the charm of the people.
Portugal is fashionable.
Last year it was awarded for the second time as Europe’s Best Destination in the World Travel Awards (WTA) They are prizes of the world tourism industry. And Lisbon turned out to be the Best City in Europe and the Best Cruise Port.
This is a selection of the best gadget power banks to charge any electronic device during a trip. Smatphone, eReaders or any accessory that can be charged by USB port. There are available from 1,000mAH to 85,000mAH.
To provide power to your travel devices, up to 89800 mah
We can find external batteries of great quality from US $ 20 to no more than 50-60 euros. Cheaper batteries usually have a capacity of 10,000 mAh, enough to charge an iPhone up to 3 times. While the most powerful batteries have up to 85,000 mAh load.
All the models in our list have a minimum capacity of 10,000 mAh to be able to charge the mobile phone at least 3 times. The most powerful batteries, + – 26,000 mAh allow to charge our mobile at least 8 times
Weight and size
Again, the weight and size are linked to the load capacity of the external battery. lighter batteries can weigh less than 10 oz (250 grams) with very small dimensions that make us not realize that we are carrying them. The most powerful external batteries usually have a weight of around 20 Oz (500 grams)
Verify that the models have the latest advances in security:
Protection against overheating
Protection against short circuits
Most of the best power bank have at least 2 output ports to be able to charge two devices at the same time. Some chargers have up to 5 output ports between USB, lightning, micro USB …
Ports of entry

Check if an external battery is suitable for air travel
The regulation specifies that the nominal capacity must be less than 100 Wh (Watt-Hour). That is to say: any power bank with a capacity lower than 27000 mAh (at 3.7V) is apt to be carried on an airplane as carry-on luggage. – See the TSA regulations–
How is the nominal capacity calculated in Wh?
Normally, the power bank specification sheet usually indicates its nominal capacity in Ah and Wh but, if you can not find it, you can calculate it for yourself:
As you already know, a power bank consists of a set of lithium-ion batteries of a certain capacity and a voltage between 3.6 Volts 3.8 Volts.
To know the nominal capacity in Watt-hour (Wh) you must multiply the total capacity of the power bank indicated in mAh by this voltage and divide by 1000:
Rated capacity (Wh) = (mAh x V) / 1000
For example: An external battery with a capacity of 20000 mAh and a voltage of 3.7V, the nominal capacity will be:
Rated capacity = (20000 mAh x 3.7V) / 1000 = 74 Wh <100 Wh

Comparing it with the Kindle, both products have made improvements from their earlier models to ensure that navigation is as simple as possible for the user. This means that they can be used by people who are ereader beginners and by children.
However, the Kindle is the best option if you are thinking about your children using your ereader, as there are more options for the children’s content available on Amazon.
Both the Nook and the Kindle have a battery life of eight weeks so they are similar in this regard. The life of the battery is one of its main concerns, any of the options would be equally appropriate.
Both e-readers have a similar price. This means that they fall in the same price range and will be of interest to people with the same budget range.
The Kindle can store over 1,000 books and includes free cloud storage for all Amazon content. This is perfect for both people who use Amazon to get content and for hardcore readers who can take full advantage of storage space.
The NOOK has a greater capacity of storage, it has the possibility to store up to 2,000 books.
