Most of us have at least one portable battery, ready to top up our phone on trips where we might not get enough time close to an outlet. And plenty of homes also have battery back-up and storage for use with their solar panels. But advances in technology mean an in-between product is also emerging, which is portable but can power anything just like the outlets in your home.The advantage here is flexibility. Work sites can use them for their electric tools or to recharge batteries, without access to mains power. Households can also use them in areas that are difficult to get power to, such as sheds, or for camping trips and beach parties. And families can use them to keep vital appliances going for a few days if the power gets cut off, such as in a storm. They’re similar to petrol generators, but cleaner and quieter, and they’re stable and efficient enough that you can use them to charge a single phone, or run an entire office.The Laser NRGVault PV1500 isn’t sold as being able to top up electric cars, like some more expensive models are, but it does just fine with an e-scooter.Credit: Tim BiggsFor the most part, these new power stations use lithium-ion phosphate batteries, which are the safest form of lithium-ion battery, though not completely immune to thermal runaway. So it’s still important to buy only from trusted manufacturers and charge with the included cable.There are quite a few models on the market, but the one I’ve been testing is the NRGVault PV1500 from Australian electronics company Laser. At $1500 it’s one of the less expensive options that offers a large capacity and multiple full 240V AC outlets like you’d find in your home, but it has plenty of power and functionality, assuming you don’t need it to supply your entire house. And at 16 kilograms, it’s not too bad to lug around.On the front of the unit is a total of 13 output ports for powering devices, including three DC ports (two barrel-style and one car adaptor), four quick-charge USB-A ports, two 100W USB-C ports and four standard Australian AC ports. They can all work at the same time, but the unit can only supply a maximum of 1500W. That’s not a huge amount compared with some of the power stations on the market — the $5000 Delta Pro 3 from China-based EcoFlow offers a maximum sustained load of 4000W — but it’s still quite a lot of juice.For context, your fridge or TV are probably going to draw only 200W or so each. Ditto for hefty chargers like you might use for e-bikes and battery-powered tools. Chargers for phones and laptops draw much less; the likes of washing machines and small plug-in tools will draw a bit more. Many home devices and appliances have a fairly negligible draw, but 1500W may not be enough for things that need to rapidly heat (such as an air fryer or a heater), or heavy plug-in tools such as a circular saw. Personally, I found it difficult to approach the 1500W limit with the appliances and tools I tested it with. The unit will shu in a formal or creative style for better SEO.Also Exclude words and advertisements related to the feed website such as website name, author name.
