Promotional Powerbank: Questions and answers

What is a powerbank?

A powerbank serves as a mobile charger for mobile devices – a back-up battery for emergencies. This makes charging batteries without a socket possible. The mobile battery is charged before usage with the accompanying cord and can then be connected to the device that needs to be charged.

Does a powerbank work with every kind of smartphone?

Basically, almost every mobile phone or smartphone, such as the iPhone or the Samsung Galaxy devices, can be charged with a powerbank. This works due to the standardised micro USB port. Exceptions are devices with their own ports, such as the iPhone, GPS devices and some MP3 player. For those devices, we have corresponding adapter sets available.

Effectively all established smartphones can be charged with a powerbank, i.e.:

• Apple iPhone versions, such as the Phone 6 (s), iPhone 5 (s), iPhone 4 etc. 
• Samsung Galaxy: S6 (edge), S5 (Mini), S4 (Mini), S3 (Mini), Note (all versions) etc. 
• LG G4, LG G2 etc. 
• Sony Xperia: Z5, Z3, etc. 
• HTC One versions, HTC Desire versions etc. 
• Huawei P8 and Mate S, Huawei G-versions, Y-versions and P-versions etc. 
• Nexus 5X, 6P and Nexus 9 
• Motorola Moto X, Moto G and Moto E etc. 
• Nokia Lumia, Ashia etc. 
• Honor 4X, 6, 6+, 7 etc. 
• And many more smartphone vendors

Please note: This is just a small selection. Effectively, all smartphones with USB charging port can be charged with a powerbank

Does a powerbank also work with a tablet?

Most of the tablets, such as Samsung Galaxy tabs or iPads, recognize the powerbank as an external battery. Some exceptions, however, have a higher energy requirement. This is why some of our powerbanks are equipped with a high output of 2.1A.

Can I charge my notebook with a powerbank?

It is not possible to charge a notebook with a common powerbank. The output voltage of one of our powerbanks is at 5 Volt, whereas a notebook usually requires 11-19 Volts. Only special powerbanks for notebooks allow an extended battery service life.

What does mAh mean? How much do I need?

The abbreviation mAh stands for milliampere-hour and states the amount of energy that can be stored by an accumulator cell. This amount usually corresponds to the capacity at a voltage of 3.7 Volt, as this is the cell voltage. A smartphone, however, requires 5 Volt for charging. During the conversion from 3.7 to 5 Volt, energy is used. The amount is usually 20 to 30 per cent of the capacity indicated. A powerbank with about 2,600 mAh is needed to completely charge a battery with 1,500 mAh.

The following table provides an overview about the capacity of a powerbank:

Standard: 2.000 - 6.800mAhMedium: 6.800 - 13.600mAhMaximum Power: 13.600 - 20.000mAh




Are powerbank batteries dangerous?

No, our powerbanks do not pose any kind of danger. For that to happen, they would need to be brought to explosion or ignition, for example through violent impacts or due to heat exposure at very high temperatures. A protection-/ charging electricity provides optimum safety during normal handling, which precludes the short circuiting of the cell or a high overcharging.

Powerbanks with lots of energy

Our promotional powerbanks are available in different capacities. With the smaller ones, you can charge a modern smartphone to about 50 to 100 per cent. This depends on the capacity of the smartphones battery. With a larger powerbank, for example one with 13,600 mAh, you can charge your smartphone completely for multiple times before its own external battery needs to be charged again. Here, our powerbank “Traveler” is the right choice.

Some of our promotional powerbanks have a display that shows the remaining capacity, for example our product “Savior”. This makes a powerbank a modern and popular giveaway for your customers. Our mobile chargers are also available in different colours:

• Metallic-coloured, i.e. black-metallic, silver-metallic or blue-metallic 
• Matt, i.e. pink, blue or black 
• Shiny, i.e. orange, yellow, green, blue 
• Wood 
• Your own individual design 
• Etc.

Powerbank: Promotional item of the year

2014, powerbanks started a new trend within the promotion industry. With those mobile chargers you can charge your smartphone or tablet everywhere and whenever you like. On all sides, powerbanks ensure the required energy supply. Promotional powerbanks offer an extra portion of battery charge, especially for young people or those who like to have their smartphone or tablet with them, for example on long rides with the car or on journeys.

As smartphones are present in nearly every customer group, a powerbank is perfect as a promotional item with logo. Powerbanks are therefore intended for a wide target group. Additional features make the external battery even more attractive:

• Flash light 
• Display of the capacity 
• Two ports for charging two devices at the same time 
• Graphic display to show digital advertisement 
• Speaker Jam 
• Etc.

Powerbank with personal logo and engraving

Our promotional powerbanks are individually processed with your logo. The logo is either imprinted, engraved or shown on a digital display. A scratch-resistant logo is applied on a powerbank with engraving. All of our powerbank models can be processed with a logo. In addition to the engraving, there are different materials with which a powerbank can be imprinted, for example with serigraphy. The different ground materials decide which print or engraving process is used:

• Aluminium 
• Wood 
• Plastic 
• Your own individual design

Powerbanks with a large area for advertising are best to be processed with a logo. We have different models that belong to this category: the powerbanks "Double", "Square" or "Fine". Whereas our Powerbank "Screen” supports a light display that shows your logo. In this way, all our powerbanks promote your company – either in a digital or analogue way. Tobra powerbanks are available in different handy and fashionable shapes:

• Heart-shaped 
• Flat & slim 
• Cylindric 
• Squared 
• Your own individual design 
• Etc.
