Check A power bank is one of the most useful gadgets today. Whenever you see your phone or your Nintendo Switch about to die, plug it to a power bank, and it’ll start charging instantly. That said, buying a power bank is not that simple as it seems. If you have purchased one and not happy with it, we believe you may have missed a few crucial factors.Check

While buying a power bank, you must consider factors like the brand name, customer service and the actual capacity of the device, among many other things. In this post today, we’ll explore the things you need to check before buying a power bank. So, let’s get started.

1. KNOW THE CONVERSION GAME

Does a power bank with 5000mAh capacity yield two full battery cycles for a phone with a 2500mAh battery? As much as we like the answer to be yes, sadly it’s not so.

The power rating is calculated at 5 volts for smartphones. But in the case of power banks, the power rating is calculated at 3.7 volts, since they carry Li-ion (Lithium-Ion) battery cells. And this difference causes a step down in the charge cycles.

2. HOW CHARGING & RECHARGING WORKS

How long can power bank hold charge? Well, it’s a little hard to tell the exact numbers, but one thing is for sure — it’s not forever. At best, you’ll get like 3-6 months, and that too when you have a high-quality power bank. Sadly, the number barely stretch a month for lesser quality power banks.

The downside is that these numbers may change. A power banks’ ability to retain charge depends on several factors, and over time, it deteriorates.

For example, if you do not charge it regularly or when you leave it in a place where the temperature fluctuation is far too regular.

3. DOES IT HAVE WARRANTY COVERAGE

Next, you’ll want to take into consideration like warranty coverage for the power bank. Also, you should check the feedback on the customer service for that particular company.

The best part is that it isn’t a difficult a task at all. All you need to do is open the review section on say, Amazon, and search for reviews that speak about the customer service.

Take the case of the Aukey 30000mAh USB-C Portable Power Bank. The reviews of this product have many reviews speaking of its excellent customer service.

4. DOES IT HAVE A POWER INDICATOR

A Power Indicator is usually an overlooked feature. But let me tell you that it is one of the most important features. Power banks lose charge over time, and if you are not careful with the charge and the recharge cycles, you may often have to pick up a dead power bank. And if you don’t have much time in your hand for juicing it up, you may end up in a sticky situation.

And that’s when the power indicators come in handy. This nifty little feature, usually in the form of tiny LED lights, lets you know the reserve energy in the product.

In a few devices, you need to shake them to know the reserve energy. While in others, there’s a little button to switch on these indicators. Whatever the case may be, make sure that the product you are buying comes with these handy LED indicators.

5. HOW FAST DOES IT CHARGE ITSELF

Imagine preparing for a trip diligently only to find out that the power bank you decided to bring as a backup, takes forever to recharge. Bummer? It would be a nightmare on long flights (or summer camps), where you don’t find adequate power backup options.

Portable power banks, especially the ones with bigger capacity, may take an awful amount of time to refuel. However, a decent capacity device with around 20000mAh capacity shouldn’t take more than 6-7 hours to replenish the charge.

The better thing to do is to look for devices that offer Quick Charge input for charging the power back as well. That way, your power bank will be charged in a decent amount of time. For instance, take the case of the Anker PowerCore 20000 which boasts of Quick Charge 3.0 in the input, owing to which refueling takes only 6 hours.

BUY SMART

And last but not least, take note of the product weight. I agre that high-capacity power banks tend to be a tad on the heavier side. But at the end of the day, you wouldn’t want to carry a product that weighs down your backpack or something which you can not slip easily into your trouser pockets.
