Best power bank for emergencies and blackouts

A good power bank can be an actual lifesaver in times of emergencies caused by natural disasters. It allows you to stay connected and reach out to loved ones or call for help if needed. Sometimes blackouts happen without any accompanying natural disaster, such as the Northeast blackout of 2003 which left millions in the dark for up to 4 days.

But a power outage can only last for a few hours or even minutes and still cause various types of damage. You could be working from home and not have enough power to attend an important meeting. Or maybe you’re dependent on a CPAP machine. Either way, having a backup power bank can prove to be a great asset during power outages.

Here are some power bank models we think you should consider getting as your emergency power backup:

The Novoo Explorer 10000mAh power bank is a nimble and rugged device. Being waterproof, it’s best suited if you’re preparing for emergency situations that involve flooding or heavy rain. Besides that, it’s also dirt-proof and shock-resistant, so it can definitely take a beating and still work. These are great features to have during a crisis.

In terms of capacity, it’s not that great as it only comes with 1000mAh, which is about 3-4 full charges of an average smartphone. But on the other hand, it features Power Delivery, which allows it to charge in just about 4h, which might come in handy for example if you were to need to recharge it using a public outlet.

Another very useful feature it comes with is the built-in flashlight. Needless to say that during blackouts, flashlights are highly useful devices to have. You’ll easily be able to find your way around your environment or find other things that you might need during the emergency. It’s also very lightweight so carrying it around will not be an issue.

All-in-all, the Novoo Explorer 10000mAh, is the right choice to have if you’re planning for just a few hours of downtime, or if you want to be prepared for flooding-type of situations. It’s also a good choice if high mobility is very important to you, as its light and easy to carry.

Best mid-range: ZeroLemon WirelessJuice 26800mAh

Emergency Portable Charger

  • Capacity: 26800mAh
  • Ports: 1 USB type C, 2 USB type A
  • Fast charging: Power Delivery
  • Weight: 19.86 oz / 563 g
  • Recharging time: 2 hours
  • Price: ~$80 (actual price might vary)

The ZeroLemon WirelessJuice 26800mAh is a very good all-around emergency power bank. At 26800mAh, it has quite a large capacity, being able to power the average smartphone 10+ times. But what’s more important is that it provides a 60W power output, which means it can easily charge laptops such as the MacBook Pro.

Maybe of its more astounding features is its ability to be recharged in around 2 hours, if you’re using a fast charger. This is pretty awesome considering the large capacity. At this rage, the average recharging time is somewhere between 4 and 10 hours. So a 2h recharging time is definitely not easy to come by and it can be a critical aspect for relying on it during emergency situations.

Another useful feature is it’s a very large LED flashlight, which basically spans almost fully on one of its sides. The flashlight comes with 4 different modes too: high intensity, low intensity, strobe, and SOS signal. All 4 modes are very useful for dealing with emergencies.

And last but not least, it comes with a survival buckle as an accompanying gift. The buckle is made of military-grade paracord and comes with a compass, a signaling whistle, a fire starting kit, and an emergency knife. Basically, and all-in-one survival kit. Maybe not as good as a professional kit, but still very useful in times of need.

What we like about it
  • High capacity
  • It can charge laptops
  • Very fast recharging time: 2h
  • Large LED flashlight with 4 modes
  • Comes with accompanying survival buckle
What we dislike about it
  • Not waterproof

  • Fast charging: Power Delivery, Quick Charge

The MAXOAK 200Wh Lithium emergency battery backup is a beast of a device. It can deliver up to 110V from it’s AC socket, 100W for charging laptops or 120W for small house-hold electrical devices. Basically you can charge almost anything with it including laptops, drones, gaming consoles, CPAP machines, tablets, etc.

All in all, if comes with 6 different power output ports which is ideal if you want to charge multiple devices simultaneously. Furthermore, it comes with an LCD display that accurately shows the charging status and other useful information such as the output power at a given moment.

It also supports being charged by solar energy. So if you hook it up to a solar panel such as the Anker 21W solar charger, then you can recharge it using direct sunlight. This can increase your autonomy by a lot, helping you deal with almost any type of crisis situation.

Overall, this is a great option if you want to make sure you have a hight amount of power available. It can easily last you through long blackouts. However, the main drawback is that the MAXOAK 200Wh is rather heavy at 7.6 lb. So dragging it around on longer distances can be a real chore in some conditions.

What we like about it
  • Ultra-high capacity
  • Multiple charging ports
  • High power output levels
  • Can be charged by solar power
What we dislike about it
  • Pretty heavy

  1. I see these suggestions for an emergency power banks. What if an emergency lasted for a week or if a brownout lasted for 2 weeks, what type of chargers would you recommend then? I presume that they would need to be solar powered.
    How well do solar powered chargers receive and hold power in general and if you have several consecutive cloudy days?

    • If an emergency situation lasts for weeks at a time, then yes, solar power could be a solution. For example, you could recharge your power bank using a foldable solar panel such as the Anker 21W https://www.powerbankexpert.com/anker-21w-2-port-usb-solar-charger/

      Of course, it’s not a fail-proof solution, as you mentioned too. But it’s still a good safety net to have.

      Now, please bear in mind that this article addresses “power banks” for emergency situations, not “power stations” which are much more powerful but also larger and heavier devices. They could provide power for a much longer time, but you couldn’t really carry an electrical power station if you’d have to leave your location.

      Anyway, we’ll append the article to include more options!
