How to Choose the Right Backup Power Source for You
Now that we have taken you through our recommendations and why we think they’re so great, it’s time to walk you through our buyer’s guide. Listed below are some of the critical criteria we believe you should be looking out for when buying your portable power station so that you don’t make some avoidable mistakes.
It’s a big market, so it’s easy to get lost in terms you may not understand. We’re here to help!
Power Rating
The first thing to understand is the power rating or wattage, indicating how many devices your backup power source can handle. All appliances and systems have different wattages. You can’t power these systems with a portable power station unless its power output equals or exceeds the system’s wattage.
Systems like the DELTA Max and DELTA Pro also have expandable capacity, meaning you can purchase one portable power station but increase its power rating with additional batteries. It’s a great way to create a robust backup power system while saving money on buying multiple backup power units.
More often than not, it’s a good idea to purchase a portable power station that will provide you with more energy than you actually need. The additional capacity will serve as a safety net if you find you don’t have enough.
Size and Portability
Portable power stations and fossil-fuel or solar generators vary enormously. Just because you see the word ‘portable’ in a product description doesn’t mean you’ll be able to carry it around without difficulty. Look at the DELTA Mini and DELTA Pro—they are both portable but have a 76lbs weight difference!
If you suspect you will need to move your backup power source around frequently, opt for a more lightweight design. A compact design will also make it easier to install in tight spaces or heights, like a home security system in the attic. It won’t pack the same power, but it may suit your needs better.
On the other hand, if you’re supplying backup power for a CCTV system for a business, school, government facility, or warehouse, you might need a more robust power backup source. Usually, size and capacity go hand in hand. Look for a larger capacity like the DELTA Max or DELTA Pro for commercial security systems.
All security systems operate differently, so make sure your chosen backup power source meets your specific needs.
Recharge Rate
The whole point of a backup power source is to provide you with energy when you need it most and, potentially, when you least expect it. A portable power station that needs extended periods to reach full charge isn’t practical for anyone — when it comes to your security systems, every second counts!
Look for portable power stations or generators that either recharge quickly or can supply your system with power while they charge simultaneously. You will have a far better experience and won’t need to worry about constant power maintenance when the backup power source isn’t in use.
Price
When we say that you should be mindful of the price, we aren’t just inferring that you should stay within your budget. While that is the case, the more important thing is to not fall for subpar products just because they have an attractive price point.
You can find many backup power sources on the market that are priced lowly and promise to deliver enormous power, but there is always a catch, whether it’s a battery with a short life span or a poorly made body. It’s always better to invest in quality.
Conclusion
There you have it! Our complete guide to the best backup power sources for security systems. Protecting your property is of utmost importance, so you need a system you can rely on in any situation. Even the best on-grid security system is susceptible to blackouts, but the recommended portable power stations will keep your system running no matter what. Ready for an outage-proof security system?
