The 10 Best Power Bank for Blackouts Reviewed
1. Jackery Portable Power Station Explorer 300
We found the Jackery Explorer 300 to be a solid contender for keeping essential electronics alive during a power outage. Its LiFePO4 battery chemistry offers a good balance of longevity and safety, which is crucial for a blackout device.

Its 150W output is quite impressive for its compact size, and the 24,000mAh capacity provides multiple charges for most smartphones and a decent boost for laptops. The build feels solid, and the matte finish resists fingerprints well.
We found it successfully charged a modern ultrabook and several phones during our testing period. The inclusion of a dedicated AC outlet is a significant convenience. My main frustration, however, lies with the somewhat clunky power button; it requires a firm press and sometimes feels a little unresponsive, which can be a minor annoyance when you just want to quickly turn it on.
This is an excellent choice for students, business travelers, or anyone who relies heavily on their laptop and needs reliable power away from an outlet. It’s not designed to power larger home appliances during a blackout, so if that’s your primary concern, look at larger power stations.

If you have CPAP machines, small medical devices, or even a mini-fridge you want to keep running, this power station is well-suited for those needs, offering a level of reliability beyond basic chargers.
While it’s a capable performer, the charging time for the unit itself can be a bit lengthy, especially if you’re relying on wall power. We also noticed the fan kicks on fairly often when under load, though it’s not overly intrusive. It’s a well-rounded option for serious blackout preparedness.
Pros
- Higher AC output wattage.
- LiFePO4 battery for longevity.
- Versatile outlet options.
Cons

8. Soaraise Solar Charger Power Bank
The SOARAISE Solar Charger Power Bank is designed with portability and outdoor use in mind, but we found its blackout utility to be somewhat limited. Its primary selling point is its rugged, weather-resistant design, which is great for camping but might be overkill for home use. The integrated solar panels are convenient, though their actual charging speed in less-than-ideal sunlight is quite slow.
We tested its ability to charge a smartphone, and it performed adequately, providing a couple of full charges. The multiple USB ports are a definite advantage, allowing for simultaneous charging of devices. However, the lack of an AC outlet means it’s strictly for USB-powered electronics, which significantly restricts its usefulness during a prolonged power outage where you might need more.
Who should AVOID this product: If your primary concern for a power bank is to run household appliances or anything with an AC plug during a blackout, you should definitely skip this SOARAISE unit. It’s not built for that purpose and will likely disappoint.
The unit feels sturdy in hand, and the carabiner clip is a nice touch for attaching it to a backpack. While it serves its purpose as a portable USB charger, its limitations in power output and lack of AC capability make it a less ideal choice for serious blackout preparedness compared to other options.
Pros
- Rugged and weather-resistant build.
- Multiple USB ports.
- Integrated solar panels.
Cons
- Very slow solar charging.
- No AC outlet.

I appreciated the clear LCD screen that displays not only the battery percentage but also input and output wattage, offering useful real-time data.
During our tests, it powered a laptop, a small TV, and charged multiple phones without issue. The inclusion of a 110V AC outlet, along with various USB ports (including USB-C), provides good flexibility. The unit’s fan is audible when the AC inverter is under significant load, but it’s not excessively loud. Recharging the unit itself takes a considerable amount of time, which is something to factor into your preparedness plans.
Real-Life Usage Scenario: Picture a winter blackout where you need to keep your Wi-Fi router running to stay connected, power a small space heater for a bit of warmth, and charge your communication devices. This EnginStar unit would be a valuable asset in such a scenario, bridging the gap until power is restored.
While the solar charging input is a feature, we found it to be more of a trickle charge than a primary charging method, especially in less-than-ideal conditions. Overall, it’s a practical and versatile power station for moderate blackout needs.
Pros
- Good AC output wattage.
- Informative LCD display.
- Versatile port selection.
Cons
- Fan can be noticeable under load.
- Long recharge time.
- Solar charging is slow.
10. Powkey 200w Portable Power Bank 146wh
The powkey 200W power bank, with its 146Wh capacity, is a compact option for basic blackout needs, primarily focused on USB-powered devices and low-wattage AC appliances. The unit feels lightweight and easy to handle, making it convenient to store in a drawer or closet. The AC outlet is a key feature at this size, allowing for more than just charging phones.
We found it could comfortably power a tablet and a small LED lamp for several hours, which is useful for reading or staying connected. The build quality is decent, though the plastic casing doesn’t feel as premium as some larger units. The buttons have a slightly soft, ‘plasticky’ feel, but they are responsive. Its main limitation is the relatively low 200W AC output, which restricts what you can realistically power.
Who should AVOID this product: If you’re looking to run anything more substantial than a laptop, a fan, or a few small electronics during a blackout, you should avoid this powkey unit. It simply doesn’t have the power output for larger appliances or medical equipment.

Frequently Asked Questions
How Many Times Can a Power Bank Charge My Phone?
This depends on the power bank’s capacity and your phone’s battery size. A 10,000mAh power bank can charge most smartphones about 2 to 3 times. Larger phones or those with bigger batteries will get fewer charges.
Always check the specific mAh rating of both your phone and the power bank. Some energy is lost during the charging process. So, you won’t get the full theoretical capacity in practice. It’s good to have a buffer.
What Is the Best Capacity for a Power Bank During a Blackout?
For a typical blackout, a 10,000mAh power bank is a good starting point. It can keep your phone alive for a few days. If you have multiple devices or larger ones, consider 20,000mAh or more. This ensures longer usage times.
Think about your essential devices. A smartphone, a small tablet, or a portable speaker might need more power. For extended outages, a higher capacity is definitely recommended. Prioritize your needs to choose wisely.
Can I Charge My Laptop with a Power Bank?
Yes, some power banks can charge laptops. You need a power bank with a high capacity and USB-C Power Delivery (PD) output. Look for models that offer at least 45W or 60W PD output. This is crucial for laptops.
Not all USB-C ports are the same. Ensure the power bank specifically states laptop charging capabilities. Check your laptop’s charging requirements. Some very high-performance gaming laptops may need more power than most portable chargers can provide.
How Long Does a Power Bank Last?
A power bank’s lifespan depends on its quality and how often it’s used. High-quality power banks can last for several years. They typically support hundreds of charge cycles before their capacity significantly degrades.
Proper care is important. Avoid extreme temperatures and fully discharging the battery regularly. Storing it with some charge, not fully empty or full, can also help maintain its health over time. This ensures it’s ready when you need it.
Are Solar Power Banks Good for Blackouts?
Solar power banks can be a useful backup during blackouts. They offer a way to recharge without grid power. However, their charging speed is generally very slow. They are best for topping up in emergencies.
Do not rely solely on a solar power bank for critical charging needs. Their effectiveness depends heavily on direct sunlight. A large solar panel is needed for substantial charging. They are more of a supplementary charging method.
Final Verdict
For blackouts, we recommend the Anker PowerCore III Elite 25600mAh. This power bank offers an excellent balance of high capacity (25600mAh), fast charging via USB-C PD (up to 60W), and multiple ports. It can reliably charge smartphones multiple times and even power some laptops, making it a versatile and dependable choice for extended power outages. Its robust build quality also ensures durability.
