Undoubtedly, the popularity of company branded power banks is constantly increasing. Since our daily routine implies the use of at least one performant, power-hungry device, it’s no surprise that power banks have become incredibly useful gadgets, carrying a huge promotional potential. Alongside tablets and smartphones, power bank batteries have become some of the hottest consumer products. As most of us already know, most tablets and smartphones do not come with a user replaceable battery. In simple terms, we do not have the option of carrying another battery around. And this is where Power Bank External batteries come in.
If you are looking for a power bank for your marketing or advertising campaign, there are several factors that you definitely need to take into consideration.
Important factors to consider when choosing a promotional power bank
Nowadays, power banks come in different shapes, sizes, and capacities. Their price can also vary considerably. Here are some key aspects that you should definitely look out for before choosing your promotional power bank.
Power banks vary by capacity, which can range from 2,000 up to 20,000mAh. If you want to make a good impression on your clients, you should definitely avoid buying a promotional power bank with a low capacity. Choosing a high capacity power bank will allow your customers to feel more secure and never worry again about their smartphones or tablets running out of battery.
Keep in mind that there are 3 main types of power banks based on usage and capacity: Business Class, Economy Class, and Special Classes.
- Their Capacity ranges from 3000mAh up to 10,000mAh
- They are capable of charging tablets and phones. Most have 2 output ports (one for smartphones, and another one for tablet or Pad)
- This is the most cost-effective alternative
- Though 2200mAh is the common capacity (industry adapted), the power banks in this class typically are under 3000mAh
- This class is ideal for charging smartphones on an emergency. It is not advisable to use this type of power banks with iPads, tablets, or other gadgets that have higher capacity batteries.
- This class of power banks may NOT always provide full charges to phones. However, they should be able to provide at least 50% to a fully power drained phone.
- The Special Class Power Banks are capable of charging phones and iPads, while some models are able to charge tablets, Notebook computers, or even start up a car when the car battery is worn out.
- This class starts at higher capacities, while some models have been tailored to suit specific market sectors.
- This is the most expensive class.
In most cases, power banks come with a single output port. This means that you can only charge one gadget at a time. However, if you know for a fact that your loyal clients use multiple devices on a daily basis, then choosing a power bank that comes with 2 output ports will definitely make a good impression and help your clients remember your brand.
Build and Warranty
If you want to impress your clients and make them feel appreciated, then your promotional power bank must have a good build and quality. The longer your promotional power bank will last, the longer your clients will remember your business and brand. So make sure you purchase a durable power bank which comes with a warranty (just in case the item has defects).
There is another important aspect that some businesses often overlook: safety!
Some of you may not be aware of the fact that External Battery Chargers can become extremely dangerous if low cost components are used in their circuit board or if Grade B (or even below) batteries are used. As a consequence, device overheating, malfunction, or even possibly high voltage transfer can occur.
The lithium ion/lithium polymer batteries are the main component of power banks. Though this type of batteries is widely used, the battery safety has always been the utmost concern. The safety of Power Banks is addressed on two fronts:
PCT (i.e. The Protective Circuitry) is acknowledged as a “Safety Valve”, meant to protect not only the equipment, but also the charged device and, above all, the user. PTC prevents Abnormal Charge/Over Charge, External and Internal Short Circuit, forced Discharge, etc.
The general Grade A concept is usually used to refer to a very good quality battery. However, having the UL battery certification represents the real test. Though most power banks come with many certifications, the most popular and safest power bank batteries have successfully passed the UL 1642 test. We are talking about a set of rigorous Mechanical, Electrical, Fire Exposure Tests, and Environmental tests. The UL certification is a widely accepted certification that ensures a battery’s compliance with a series of recognized safety requirements.
Reducing the costs of power banks is rather simple; some manufacturers cut out the costs of protective circuitry and battery certifications. However, by doing so, they are creating a tangible risk not only to the safety of power banks, but also to the safety of the charged gadgets and even the user.
Avoid buying the cheapest power banks
Though a low price might be tempting, you should keep in mind that, in order to cut costs, some manufacturers encase their external battery chargers in plastic. It is impossible for you to know the quality of their internal components. The price is – in most cases – a good indicator that inferior, dangerous internal components are being used. And the last thing you want is to endanger your customers’ safety. In exchange, if you opt for a good value promotional item, you will provide your recipients not only with maximum use cycles, but also with the maximum possible safety and peace of mind.
Safety is the key
As with all electronic and electrical devices, it is extremely important to treat power banks with care and respect, thus ensuring they continue to work safely and properly. Below you can find a list of general Dos and Don’ts:
Use power packs only for their intended use (i.e. recharge mobile phones and similar USB powered mobile devices)
Keep them away from liquids and heat sources (i.e. direct sunlight, water, or humidity)
Only use the connecting cables that have been provided with the battery pack or your mobile device.
Supervise children when using battery packs.
Expose power banks to extreme temperatures (cold or hot).
Don’t leave the battery pack on prolonged charge if not in use.
Don’t store power banks where they can short-circuit by conductive material (for example a bag with keys or coins).
Don’t roughly handle or drop battery packs. Though they are robust, they are not indestructible.
Make sure not to cover them when charging.
Make sure the environment is well-ventilated when charging.
Don’t attempt to repair or dismantle faulty battery packs.
If a cell is leaking, make sure that the liquid does not come into contact with the eyes or skin. If contact is made, make sure to wash the affected area(s) with water and ask for medical advice.
