Portable power stations have gone from niche camping gadgets to essential home equipment in a remarkably short time. In New Hampshire, where ice storms can knock out power for days and rural properties often sit at the end of long utility lines, having a reliable battery backup is no longer a luxury — it is a practical necessity. In fact, backup power is the foundation of any serious winter emergency kit for your home.
The market has exploded with options ranging from compact units that charge your phone a dozen times to massive systems capable of running a refrigerator, sump pump, and medical equipment simultaneously. Finding the right balance of capacity, output, portability, and price requires understanding what you actually need to power and for how long.

How to Choose the Right Portable Power Station
The most important specification is watt-hour capacity (Wh), which determines how long the unit can power your devices. A 1,000Wh station can theoretically run a 100-watt device for 10 hours, though real-world efficiency means you should plan for about 85 percent of the rated capacity.
Continuous wattage output determines what devices you can run simultaneously. A station rated at 2,000 watts continuous can handle a refrigerator, a few lights, and a phone charger at the same time. If you need to run high-draw appliances like a space heater or a well pump, you will need a higher-output unit or an expandable system.
Charging speed matters when the power goes out unexpectedly. Some modern units can recharge from a wall outlet in under an hour, while others take 8 to 10 hours. Solar charging capability is a significant advantage for extended outages where grid power is unavailable.
For New Hampshire homeowners, the most common use cases are keeping a refrigerator running during winter storms, maintaining a sump pump during spring snowmelt, powering medical devices like CPAP machines, and running a few lights and chargers to stay comfortable and connected.
Best Overall: EcoFlow Delta Pro 3
The EcoFlow Delta Pro 3 represents the current state of the art in portable power. With a base capacity of 4,000Wh that is expandable to 12,000Wh with additional batteries, it bridges the gap between a portable power station and a whole-home backup system.
The Delta Pro 3 outputs 4,000 watts continuous with a 8,000-watt surge capacity, which means it can start and run demanding appliances like well pumps and window air conditioners that cause other units to trip. For New Hampshire homes that rely on well water, the ability to keep the pump running during an outage is a meaningful safety feature.
Charging speed is where the Delta Pro 3 really shines. It can recharge from 0 to 80 percent in about 50 minutes via a standard wall outlet, and it supports 1,600 watts of solar input for off-grid charging. The unit integrates with EcoFlow’s home panel to serve as an automatic backup — when power drops, it switches over in under 20 milliseconds, fast enough that your devices do not notice the interruption.
The price is substantial, but for homeowners who want generator-level backup without the noise, fumes, and maintenance of a gas generator, it is the most capable option available. If you do want that permanent, automatic protection, our guide to the best whole house generators covers standby systems that kick on the moment power drops.
Best Value: Jackery Explorer 1000 Plus
The Jackery Explorer 1000 Plus hits a price-to-performance sweet spot that makes it the easiest recommendation for most people. With 1,264Wh of capacity and 2,000 watts of continuous output, it can run a full-size refrigerator for roughly 13 hours or power essential lights and devices for a couple of days.
Jackery has earned a reputation for reliability and straightforward design. The Explorer 1000 Plus has a clear LCD display showing input and output wattage, remaining capacity, and estimated runtime for your current load. Two AC outlets, two USB-C ports, and two USB-A ports provide flexible connectivity, and the unit weighs about 30 pounds — heavy enough that you would not want to carry it on a hiking trip, but light enough to move between rooms or toss in the car.
The 1000 Plus supports expansion with additional battery packs if you find you need more capacity over time, and it charges to 80 percent in about 90 minutes from a wall outlet. Solar charging via Jackery’s panels is also well-supported and straightforward to set up.
For the homeowner who wants reliable backup for essentials during a typical 12 to 24-hour New Hampshire power outage, the Jackery delivers without overcomplicating things.
Best for Camping and Portability: Anker SOLIX C300 DC
If your primary use is camping, tailgating, or having a grab-and-go backup for short outages, the Anker SOLIX C300 DC is compact, affordable, and thoughtfully designed. At just under 8 pounds with a 288Wh capacity, it is genuinely portable in a way that larger units are not.
The C300 DC does not have AC outlets — it is a DC-only unit with USB-C, USB-A, and a car cigarette lighter port. That means it will not run a refrigerator or a lamp with a standard plug, but it will charge laptops, phones, tablets, cameras, drones, and portable fans for days. For weekend camping trips to the White Mountains or as a car emergency kit, it covers the essentials.
Anker’s build quality is excellent, and the C300 DC includes a built-in LED light with adjustable brightness that is more useful than it sounds when you are setting up camp in the dark or navigating a house during a blackout.
Best for Extended Outages: Bluetti AC200MAX
New Hampshire’s worst power outages are not the 6-hour inconveniences — they are the multi-day events caused by ice storms and heavy wet snow that bring down trees and power lines across entire regions. The 2008 ice storm left some areas without power for over two weeks. For that kind of scenario, the Bluetti AC200MAX is built to sustain.
The base unit provides 2,048Wh of capacity with 2,200 watts of continuous output, which is enough to run a refrigerator, a few lights, and charge devices through a full day and night. But the real advantage is expandability — you can add two B300 expansion batteries to reach 8,192Wh total, which stretches essential-only usage to four or five days.
The AC200MAX accepts up to 900 watts of solar input, which makes it a viable indefinite power source when paired with a couple of panels. Even in New Hampshire’s winter, shorter days and overcast skies still produce meaningful solar charging, and having any recharge capability during an extended outage is dramatically better than watching a fixed battery count down to zero.
The unit supports both solar and AC charging simultaneously, so on a partially sunny day during an outage you can run your essentials and recoup some capacity at the same time. It is heavy at about 62 pounds, but it is not meant to be portable so much as movable — you position it once and let it work.
Best for Medical Device Backup: EcoFlow River 3 Plus
If your primary concern is keeping a CPAP machine, oxygen concentrator, or other medical device running during outages, the EcoFlow River 3 Plus offers the right combination of capacity, clean power output, and fast charging for that specific use case.
The 286Wh capacity will run a typical CPAP machine for two to three nights, and the pure sine wave AC output ensures sensitive medical equipment runs smoothly without the electrical noise that can cause alarms or malfunctions. The compact size means it fits on a nightstand or bedside table, and the near-silent operation will not disturb sleep.
Fast charging is particularly important for medical backup — the River 3 Plus can fully recharge in about an hour, so you can top it off quickly when you know a storm is approaching. The unit also supports pass-through charging, meaning you can keep it plugged in and charging while simultaneously powering your CPAP, providing seamless backup when the power cuts.
For the estimated 22 million Americans who use CPAP machines, including a significant population in New Hampshire’s aging demographics, this kind of targeted backup can be genuinely life-improving.
Solar Panels: Worth the Investment
Pairing your portable power station with solar panels transforms it from a finite battery into a renewable power source. For New Hampshire homeowners, this is particularly valuable during the extended outages that occasionally hit rural areas.
Most major power station brands offer matched solar panels designed to work seamlessly with their units. A 200-watt panel will typically produce 100 to 160 watts under real-world conditions, depending on angle, cloud cover, and temperature. Two panels paired with a high-capacity station can keep a refrigerator running indefinitely on sunny days and provide enough charge to get through cloudy stretches.
Solar panels also serve double duty — they are valuable for camping, RV trips, and off-grid cabin use. New Hampshire’s extensive network of campgrounds and backcountry sites makes solar a practical accessory beyond just emergency preparedness. For those interested in New Hampshire’s own role in the energy supply chain, recent USGS surveys have identified lithium deposits in the state that could eventually support domestic battery production.
How Much Capacity Do You Actually Need?
A common mistake is buying too small. Here is a rough guide based on typical New Hampshire power outage scenarios:
For keeping phones and tablets charged plus a few LED lights, 300 to 500Wh is sufficient for a couple of days. For running a refrigerator through a 24-hour outage, plan on at least 1,000Wh. For comprehensive home backup including the refrigerator, lights, internet router, and device charging over multiple days, you want 2,000Wh or more, ideally with expansion capability or solar charging.
If you rely on well water, factor in your well pump’s power requirements — most residential well pumps draw 750 to 1,500 watts, which requires a higher-output unit. This is a common consideration for rural New Hampshire properties that cannot rely on municipal water during outages. The Department of Energy’s guide to emergency power and Consumer Reports’ portable power station ratings are helpful resources for sizing your backup system. And if winter outages are your primary concern, pairing a power station with a pellet stove that has battery-backup capability can keep your home warm even when the grid goes down.
Can a portable power station run a refrigerator during a power outage?
Yes. A power station with at least 1,000Wh capacity and 1,500 watts of continuous output can run a standard household refrigerator. Most modern refrigerators draw about 100-200 watts while running, so a 1,000Wh station can keep one running for roughly 8-15 hours. For longer outages, pair the station with solar panels for renewable charging.
How long will a portable power station last during a New Hampshire ice storm?
Duration depends on capacity and what you are powering. A 2,000Wh unit running just a refrigerator and a few LED lights can last 24-48 hours. With solar panels providing daytime recharging, you can extend that significantly. For the multi-day outages that occasionally hit New Hampshire, expandable systems like the EcoFlow Delta Pro 3 or Bluetti AC200MAX with expansion batteries offer the most sustained backup.
Are portable power stations better than gas generators?
Each has advantages. Portable power stations are silent, produce no fumes (safe to use indoors), require no fuel storage, and need virtually no maintenance. Gas generators offer more raw power for less money and can run indefinitely with fuel. For most New Hampshire homeowners, a high-capacity power station covers typical outages more conveniently, while a gas generator may be necessary for running high-draw equipment like well pumps or heating systems for extended periods.
