How to Properly Store and Maintain a Power Bank
Whether you’re buying a high-capacity power station or a pocket-sized portable charger, any power bank you buy is essentially a big battery sitting in a shell that you don’t use often. And when not in use, power banks can slowly run out, gradually losing their charge capacity. We want your super power bank to last as long as possible. These three easy-to-remember rules will keep yours from turning into a ticking time bomb that betrays you and leaves you with a dead phone at the worst possible time.
1. Do NOT leave it at 100% or 0%
Batteries are stressed the most when they are almost completely full or completely empty. This is why years ago you were told not to leave your phone on the charger overnight as it will shorten the battery life. Nowadays, battery technology has improved and features such as load matching are used more widely to charge intelligently and avoid stress when a battery is above 80% or below 20%.
While phones and laptops can use smart charging to only charge a device the last 20% right before you’re supposed to wake up, power banks aren’t used as frequently and therefore can’t charge a device. ‘use. You have to manually charge it before using it, leading many owners to leave portable batteries plugged in all the time.
Do not leave a power bank plugged in for long periods of time
Leaving a power bank at 100% can damage its ability to hold a full charge, turning your 10,000mAh portable charger down to 9,000mAh or even less if left on the charger for weeks at a time. Granted, power banks will inevitably lose some capacity over their life cycle, as rechargeable batteries don’t last forever, but leave them plugged in perpetually at increasing speeds.
Conversely, if you leave a power bank on a shelf for months or years, it can slowly fail completely, irreversibly. If your battery drops below its minimum threshold and stays there long enough, no amount of charging will ever bring it back to life.
Instead, we need to charge power banks most of the time to help minimize battery strain. Next, we need to make sure the battery is recharged from time to time to keep it from dying forever, which brings us to our next rule.
2. Use them once a month whether you’re on the go or not
You might not take a vacation or an extended day trip every week, but even if you’re home, you still need to use your power bank once in a while. Seriously, set a reminder on your phone to charge your phone – or other device, depending on charging speed/capacity – once a month.
Running the battery down a bit and then charging it back up to 60-80% once a month gives you a few benefits:
- It prevents the lithium-ion battery cells inside from failing due to over-discharge.
- It ensures that every day your power bank is at least over 50% charged and full enough to charge your phone at least once.
- It reminds you that you have a portable battery that you can grab on your way out of the house. (Yes, really, there’s no point in your power bank staying at home when you’re having a night out on the town or a long day.)
Recharging it once a month also gets you in the habit of using a power bank, so you can get familiar with its controls, charging speeds, and battery level. This will help you notice any significant changes or excessive heat buildup during regular charges, which will tell you when the bank is failing so you can replace it, rather than when you’re relying on it.
3. Store away from high heat, intense cold and sunlight
Between these periodic charges, you need to consider where your power bank is stored. Some people like to keep them by the front door so they’re easy to grab on the way out, while others hide them on those ridiculously cluttered shelves in the home office. Personally, both are fine as long as they’re out of direct sunlight and in a climate-controlled room.
Extreme temperatures aren’t good for batteries, so for sanity’s sake, never store a power bank in your car. They get super hot in the summer, super cold in the winter, which will cause the batteries to degrade faster. If you live somewhere with triple-digit summers, leaving your power bank in a car for days on end could very well cause it to swell, break, or catch fire.
While there’s nothing wrong with storing a power bank in the box or in a drawer, having the power bank visible on your desk or on the shelf in the shade allows you to throw a glance and notice if anything begins to bulge or tilt. time.
Choose a suitable power bank
Proper power bank storage can help your current bank last as long as it can, but if yours is already losing capacity, choosing the best bank for your charging needs can help ensure the new one lasts. some time. We have a detailed guide to buying Power Delivery power banks, but to start, you should only buy power banks that support Power Delivery as they have wider compatibility and have faster recharge rates. than power banks with micro-USB or mini-USB charging.
If you need suggestions for great USB-C Power Delivery portable chargers, we’ve got plenty for your perusal, from pocket-sized power banks to heavy-duty laptop-compatible batteries. For most users, I recommend something in the 10,000-15,000 mAh range, as this will charge a smartphone 2-6 times, depending on the capacity of your particular phone, and they’re still light enough to slip around easily in your bag.
