Power Banks: Are they safe and do I need one?
Mobile technology has come a long way over the last 10 years with smartphones, tablets, cameras, and music devices dominating our everyday lives. And with every picture we take, text we send, call we accept, and song we pump through our Bluetooth speakers we’re draining battery life that must be replaced to keep the good times going.
Maintaining that mobility, convenience, and freedom to go about your means you can’t simply stop to plug your device into the wall in the middle of whatever’s going on.
And thus, the power bank portable charger was created.
Understanding Power Banks
Plugging your phone or tablet into a wall socket works just fine, certainly, but when you’re out hiking and taking pictures, or spending a day at an amusement park with your kids, you need a power bank to let you charge your devices on-the-fly, so you never miss a great moment or once-in-a-lifetime picture.
The real question then becomes, “Are power banks safe?”
You’ve no doubt seen the hundreds of different sizes and styles of power banks, each with their own inputs, lithium batteries, and milliamps per hour (mAh), but that doesn’t mean they’re safe for you to stuff into a backpack, briefcase, travel bag, or purse for charging devices on the go.
Choosing the right fast charge power bank comes down to a few factors that you need to know about, and we want to help you understand each one to make the right choice for you, your family, and your travels.
Three Distinct Categories
First and foremost, power bank portable chargers are broken into three distinct classes based on capacity and general use: Economy, Business, and Special.
General a more common capacity that’s designed with a low price point and basic capacity ranging from 2200 mAh to 5000 mAh. These are mostly for quick and short use, which rarely provide even a full phone charge.
Backed by capacity that extends up to 10000 mAh, these multipurpose external battery chargers are the most vital addition to today’s tablets, smartphones, and mobile devices. With multiple ports and type C accessibility, their versatility, like that found in the Crave Plus, is ideal for most users.
The most versatile of all power banks, these chargers are led by products like the Crave Plus Pro which power a wide range of devices you use most often, including smartphones, tablets, cameras, GoPros, and even certain laptops and Apple MacBook computers.
The first thing to understand about charge capacity is that just because something is rated 2200 mAh or 10000 mAh doesn’t mean that’s the speed at which it will charge. It simply means that’s how much stored energy it can. Generally speaking, the lower the number, the less effective it will work for charging your gear.
When estimating how many charges you can expect from a power bank, it is important to remember that power transfer from a power bank to your device is not 100% efficient. In fact, low quality portable chargers can have as much as 50% power loss, which would mean a 10000 mAh battery will only power up your device battery 5000 mAh. Premium quality power banks perform much better and will have a loss of around 30%.
The Apple iPhone X has a battery capacity of 2700 mAh. If you are looking at a high-quality power bank with 10000 mAh, you can expect almost three full charges for your iPhone. The math would be as follows:
10000 mAh capacity x .70 efficiency = 7000 mAh effective capacity / 2700 mAh iPhone X battery capacity = 2.6 full charges.
When it comes to portability, safety is the most important factor behind choosing a slim power bank.
Does it good too hot in your bag? Does it overcharge your device? Could it cause a short circuit and damage your device or it’s charging capability? Can it adjust to your specific device or is it stuck with one setting?
Unfortunately, with most standard power banks, you’re playing the lottery in terms of protection and overall safety. Average power banks have even been known to start fires, melt down, or even explode due to a variety of very specific factors, including:
When a brand skimps on the type of lithium-ion battery they use, it can play a major factor in rechargeability and battery to device stability. Remanufactured and recycled batteries found in average power chargers increase safety risks exponentially.
Poor circuit quality and connectivity between parts also play a critical role in overall dependability. In fact, without certain safety standards in place poor circuits can cause overvoltage, short circuiting, and even rapid changes in internal and external temperatures.
Unfortunately, people don’t always use their power bank correctly. Exposing it to high external temperatures can be problematic, as can spilling water or liquids on the battery itself. Overcharging the power bank itself can be detrimental to inferior products and trying to charge incompatible devices puts both items at risk.
