South Africa's electricity crisis: Four full months of power cuts fuelling violent crime

You lose some of the power and capacity you get with our larger picks—don’t expect to run an air conditioner or charge multiple laptops—but you save on space . The BigBlue 28W USB Solar Charger is the USB solar charger wed pack for a week in the woods or a month in Malawi. It produced the most power of the models we tested and offers several standout featuresan additional output port, a weatherproof port protector, and an expansive array of panels to catch every last ray of sunlight.

The Ryno-Tuff 21W also impressed us in this metric, especially considering its humble 21-watt capacity. This panel charged our phone 34% over the course of a 30 minute period. Every company that sells portable power stations provides the expected number of watt-hours its products are supposed to last. For the Jackery Explorer 240, that's 240 watt-hours; for the Ecoflow River MAX, it's 576 watt-hours. Portable power stations are generally designed to power smaller electronic devices and appliances, from phones and table fans to heavy-duty work lights and CPAP machines. Pay attention to the estimated watt-hours each brand provides in its specs to determine which model makes the most sense for what you'd like to power.

That day, the Electric Cooperatives of Arkansas asked people to limit their power usage by lowering thermostats, skipping showers and holding off on using a clothes dryer or dishwasher. The Southwest Power Pool manages the electric grid for Northwest Arkansas and the River Valley, as well as parts of Oklahoma, Louisiana, Texas, New Mexico and all of Kansas. SWEPCO, OG&E and dozens of other companies use electricity managed by the pool. We face big challenges to help the world’s poorest people and ensure that everyone sees benefits from economic growth. Data and research help us understand these challenges and set priorities, share knowledge of what works, and measure progress. We provide a wide array of financial products and technical assistance, and we help countries share and apply innovative knowledge and solutions to the challenges they face.

There is some amount of power that goes to fuel the various indicator lights and readable led panels on the units. Some of the larger units even have their own operating systems, so it's almost like powering an additional mini-pc on the inside. Other units can have power-saving features where they reduce outgoing bulk power as they near depleting their charge. If a company says its portable power station has 200 watt-hours, it should be able power a device with a 1-watt output for about 200 hours. Next, many of the current-gen power stations are coming with a "UPS Mode" to offer backup power to critical pieces of equipment during power failures. You plug the power station into your wall outlet and the equipment in question into your power station.

She also spoke with Professor Gerbrand Ceder, an expert in energy storage, about home battery systems. The name is instantly recognizable, and its sleek aesthetic means this storage system fits into any design, indoors or out. The AC-coupled battery backup is included when you purchase solar tiles or solar roof tiles .

If you find that you often forget to carry your backup battery when you need it most, you should consider a dedicated battery case instead. It combines the portability and protection of a case with a built-in power cell to keep your phone topped off at all times. The downside is that they often have lower charging capacities than dedicated batteries and that you can't charge much else with them. Pass-through charging is another feature to consider; with it, you can charge devices and the portable power simultaneously. That's convenient if both your phone and backup battery are running on empty. You shouldn't encounter any safety issues if the manufacturer of the portable battery you buy advertises pass-through charging as a feature, but the power output might change in this mode.

It’s a no-brainer recommendation if you’re in the market for a dependable power source on-the-go. To run our capacity tests, we connect some number of 10,000 lumen LED work lights rated at 110 watts to each unit (the number of work lights is based on the overall watt-hour rating of the unit under test or UUT). We record the outgoing voltage and wattage using external measurement instruments or the UUT's own measurements if available.

So, our cake decorator actually had to go to our other location in Cary to keep decorating cakes." Generators and battery-backed alarm systems have kept those in wealthier areas safe. In a country with some of the highest inner-city crime rates in the world, night-time power cuts have been detrimental to public safety.

At the opposite end of the scale is MAGFAST Extreme – the one that can jump-start your car. Extreme is a super-charger with the power to boost your battery life for days due to its staggering 18,500 mAh capacity. It is also the world’s first portable charger with three Qi wireless charger stations – ideal for all your devices or when sharing with family or friends. When there are more solar cells on a charger — or larger cells — they can generate more power. Gordon noted that some solar battery banks only have one panel, limiting the amount of power they can generate.

Next, we recharged the battery, this time using the AVHzY to track it and chart the amount of time it takes to reach full charge. (Most manufacturers say you should calculate expected usage at 85% of stated capacity.) Two of our smaller units both clocked 98% capacity -- the Jackery Explorer 240 and the Togo 350. The largest units did better, with the Bluetti AC200P scoring highest at almost 96%. Now, if you blindly accept both a unit's stated capacity and our work light wattage rating of 110 watts, the numbers look very different.

Our pick: Jackery Explorer 1000

The Explorer 1000 isn’t the most powerful of the models we tested—several bested it when it comes to capacity, max output, or both—but it still offers an impressive amount of power for the price. Plus, it’s much lighter than those models, so it’s more practical to lift into a trunk or carry to the backyard. Nearly identical to its larger, more powerful sibling, the Jackery Explorer 300 weighs just 7 pounds and has two AC outlets, two USB-A ports, and a USB-C port—more than most other lightweight options we tried. We like to bring it to a beach, park, or campsite to inflate an air mattress, run a fan, or charge a phone, camera, portable speaker, lantern, or headlamp.

Mazumder said people often buy new models of electronic devices and do so at a faster rate compared to buying solar power banks and other charging accessories. Thus, the type of port on your new phone might not match the port on your two-year-old solar power bank, causing you to have to purchase adapters to continue to use it in the future. Power output and efficiencyEvery device is designed with a different size battery, which can help guide your shopping.
