3 Things You Should Know When Buying A Power Bank

Today’s modern gadgets need to be connected to a power supply more frequently than one would like. Simple things like a Smartphone, a tablet do not have a large enough battery to power them for a full day. Things are even worse when looking at laptops which can barely run on battery for more than four hours. Power banks offer a convenient solution that can supply a bit more energy for these devices. Here are 3 important things to look out for when shopping for a power bank.

1. Price & Quality

The price and quality of a power bank is mainly determined by its capacity and build. It is a combination of both that can help determine which products are worth spending money on and which ones should be disregarded. This also includes the type of batteries used and additional features such as over-charging protection and portability. To be noted that the portability of a power bank is also conditioned by its capacity. Weight and size of a power bank increases proportionally with its capacity. These aspects need to be taken into consideration as portability can be an issue for the ones that need to travel light and do not need to pack heavy objects. Lighter power banks can be carried in a back pack while large capacity ones should be tossed into a trolley.

2. USB Charging

Even if USB charging is just a feature it is highly important. A power bank that comes with a USB charging can be used for multiple devices. Cell phones, tablets and other gadgets support USB charging. This feature improves compatibility and expands its usage scope. High quality power banks come with all the required cables to charge various devices that use mini-USB, micro-USB or thunderbolt charging.

3. Capacity

The capacity of a power bank is the most important characteristic to look at when shopping for such a device. It will determine how many times it can charge a device and how big the power bank will be. The capacity is measured in mAH or milli Ampere Hour. The devices it can charge usually also have a capacity shown using the same measurement. To get a better picture of just how many times a power bank can charge a battery of a device it is enough to divide the capacity of the power bank to the capacity of the battery of the device. For example a 3000 mAH power bank can charge two times a 1500 mAH battery. It is important to understand that higher capacity power banks are not only a heavy but difficult to carry around.

How To Choose The Best Power Bank

Power Banks became more of a mandatory add-on item for every gadget enthusiast that likes to travel and enjoy using his smartphone or tablet without interruption even if there is no power supply around. When talking about how to choose the best power bank we end up looking at a bit of math. A decent power bank needs to offer a decent value for money and it should not be that heavy.

The very first thing that needs to be taken into consideration is the capacity. Determining the value for money of a power bank requires a simple division of mAH and price. This will show the actual value of how much a mAH is worth for every dollar spent. A relevant comparison requires this calculation for multiple models and as expected the bigger the value of the division the better. In general this ratio should vary a lot from one model to another. As the ratio grows so does the value of the product but this is not the only thing that matters.

The second aspect that should help chose the best power bank is the weight. In all cases the weight of the product will vary. There are multiple elements that influence the weight such as the type of batteries used, the enclosure and so on. To make it easier to compare and decide which one is better the capacity must be divided by the weight. This will obtain a mAH per weight ratio which can be used to compare multiple products and the higher the number the better. Ideally the best power bank will offer a decent capacity without being too heavy. It makes no sense to get a power bank that cannot be carried in a backpack due to its weight.

Last but not least, the build quality and design should help determine which power bank to buy. After the mAH per dollar and weight are determined a selection of models can be made and out of the ones that remained one needs to be picked based on its overall build quality and visual aspect. Most power banks have a plastic exterior but there are a few with aluminum casing which helps dissipate heat better.

These simple checks should help pick a rather reliable power bank. As an additional note, connectivity might prove to be an important aspect but these days almost all of them support USB charging which makes compatible with a wide range of devices.
