6 Factors You Should Notice When Purchasing A Surface Pro External Battery

Generally, there are several factors you have to first consider before determining which surface pro external battery is the most compatible with your situation. The factors will be detailed below and by understanding the trade-off between each feature, you will avoid purchasing an unsuitable device. 

Capacity

Capacity will determine how many times you can fully charge your device, therefore, the higher the capacity, the longer your laptop will run. However, higher capacity also results in a heavier power bank that takes more time to recharge. Therefore, you should consider how much additional time you need from the power bank so that you can pick the perfect portable charger that fits your use case at a minimized weight. Additionally, you should go for devices with clear indicator lights, which can let you know how much energy is left in the charger and other useful information.

Safety

Power banks that come with protective circuitry (PTC) will prevent the device from short-circuiting, over-charging, and overheating. This means the power banks will have better longevity and safety when used. Additionally, the type of battery the bank uses can be of different types and a lithium-polymer battery is less likely to cause a fire than a lithium-ion battery. High quality power banks usually come with various internationally recognized certifications, and power banks that have the UL (Underwriters Laboratories) certification are the ones that have overcome rigorous auditing and testing.

Build quality

You should avoid fragile power banks made of cheap plastic to ensure durability. Instead, you should look for power banks built from materials like silicone rubber, polycarbonate, anodized aluminum, or PC-ABS (polycarbonate acrylonitrile butadiene styrene). Most of these materials are fire-resistant and shock-resistant, meaning the device will be able to withstand drops or high temperature environments. Overall, the most durable and rugged power bank should have passed rigorous temperature, vibration, and shock tests before getting to the hand of the consumer, therefore, if you see mention of those procedures or materials then you can be more confident that the portable charger has good build quality.

Type and number of ports

A power bank that has a diverse collection of ports will be able to help you charge multiple devices at the highest efficiency. For example, a power bank with an additional high-capacity port will allow you to quickly charge compatible devices like your phone while still being able to charge your laptop, however, to utilize these high-speed functionalities, you must have a suitable cable that can deliver high currents.

Brand and warranty

By sticking with established names like Anker, PatPower, MAXOAK, and many more famous brands, you will avoid ambiguity and uncertainty. Unbranded power banks made by obscure manufacturers are prone to causing issues, sometimes at the cost of your devices. Sticking with established brands means you will receive a reasonable warranty period. And in cases where the manufacturers offer you a long warranty (3 years for example), this means they are confident in the quality of their product and you can rest assured that your purchase will be worthwhile.

Power output and power input

Power output dictates the charging capability of the power bank while the power input dictates the speed of recharging your portable charger. Generally, you should pick an external battery that can both provide and receive a quick charge because you will save a lot of time. If a power bank supplies more power than your device demands, your device will simply accept as much current as it possibly can. Therefore, going for high output portable chargers is beneficial. In some cases, a high-quality power bank can charge other devices while being charged, resulting in all of your electronics fully loaded, which is very convenient.

How To Take Care Of Your External Batteries More Properly

Now that you’ve selected your favorite power bank, you should also know how to store it properly to ensure longevity for the portable charger in a situation where the portable charger is left unused for a long period of time.

The problem

Lithium batteries will become useless if they are fully discharged. This means they will permanently lose the ability to charge and recharge. However, if you use a power bank normally until it drops to zero percent, this is not harmful because the device is shutting down before the battery voltage falls too low. If the power bank is recharged within a few days, it will be fine. In contrast, if you don’t charge it after having used all of its power, the battery will self-discharge while the monitoring electronics use the rest of the energy, leaving your power bank fully discharged in a few weeks, which makes the cell unable to recharge, thus turing the entire portable charger into junk.

The solution

The best way to store your power bank is to charge the battery to around half full before storing it. Then you should recharge it once a year if left unused. This will make sure the battery is in the safe zone and reduces aging. Charging the power bank to 100 percent before storing will allow a longer period between “refreshing” charges, but it will age the battery faster. This is because cells lose capacity faster when charged to 100 percent than when charged to 50 percent or less. Therefore, charging the device at mid-capacity will be the best for preserving the strength of the power bank. Additionally, the environment in which the power bank is preserved should be dry, well-ventilated and in between 15 to 25 degrees celsius for the best results after long periods of storage.
