The popularity of mobile emergency chargers has increased tremendously over the past years. We are on the road more than ever and want to be connected at all times. The good old days that you could use a telephone without recharging the battery for 2 or 3 days or even a week are over. Today we are already happy if we make it through the day without our battery getting low!
A mobile emergency charger is a smart solution for anyone who frequently uses smartphones or other compact mobile devices. You no longer need to search for a connection to the current power and can charge your device wherever you are.
Are you thinking about purchasing a mobile emergency charger? These things might be useful to take into account:
- Battery quality: Unfortunately, with the rise of popularity of mobile emergency chargers many low quality products entered the market. These, often cheap, versions mostly do not comply with international quality guidelines such as CE and ROHS. The lack of good internal circuit protection might cause overcharging and overheating. This can cause damage to the mobile device you are charging and to the charger itself. It eventually might even cause an explosion! So always check if the battery charger you want to use is sold by a trusted party and if the battery is reliable. For example, the PowerTube of AVANCA® is equipped with the last generation Samsung Li-ion battery, complies with all quality qualifications and is therefore safe to use.
- Size and weight: An emergency charger will be often used on the road. Daily while travelling to work, during a concert or football game or outdoor activities. This calls for a lightweight solution. The rule often is: the more powerful the charger, the bigger and heavier the battery. Make a mental note of it. If you end up buying a large, heavy charger, the result might be that you don’t use it.
- Enough capacity: Which device are you planning to charge most frequently with the emergency charger? Smaller devices such as smartphones, often have a battery with a capacity of 1400-2500 mAh. When you buy an emergency charger with a capacity of 2200mAh, you will be able to charge your smartphone 1 to 1,5 times (basic rule: capacity of the emergency charger / capacity of the device = the number of times you will be able to charge it. Always round up to a lower number, because the charger will lose some energy while charging your device). With a capacity of 5000 mAh – for example the AVANCA® Powerbar Pro 5000 – you will be able to charge an iPhone 5 three times. Always check the capacity of the emergency charger and compare that with your mobile device.
- Voltages and ampères: Besides the battery capacity, the electricity tension and amount of electric charge is important. Most compact emergency charger have a tension of 5 volt and deliver 500 milliampère til 1 ampère of power. For smartphones, this is enough. Larger, heavier tablets often require 2.1 ampère power. A smaller, compact charger will be able to charge certain tablets (such as iPad Mini), but charging speed will be slower. Always check the required voltages and ampères of the device you want to charge.
- Compatibility with your mobile device: Some mobile chargers are especially designed for one device. In most cases, a universal charger is the best option, as you can use it with any device. If you want to change your smartphone in the future, you don’t have to change your emergency charger as well. Check if cables are included with the charger of if you can use your own cables.
- Charging time and technique: How do you need to charge the emergency charger? Does charging require a special adapter (and if so, is the adapter included?) or can you use a standard USB-charger, available in many homes and offices? Take also a closer look at the charging time of the emergency charger. Larger chargers often need more time to be fully charged. The minimum charging time for AVANCA® emergency chargers is 3 hours. Of course you can also charge the battery for a smaller part.
This leaves us with the +1 tip, which might be completely redundant
- The looks: never judge an emergency by its cover… Well, we do not completely agree. Of course esthetics are important. So choose the shape, color and material you like.
