Anker Powerhouse Portable Generator

Anker PowerHouse: The Small Anker Solar Generator Line Explained

The PowerHouse name covers Anker's compact power stations, the ones you carry in one hand to a picnic table, a tent or a desk during an outage. An Anker solar generator in this size class stores a few hundred watt-hours, charges phones, laptops, cameras, a CPAP or LED lights, and recharges from a wall outlet, a car socket or a small folding panel. It is the right starting point for people who do not need to run a refrigerator or power tools.

This collection currently lists two units: the Anker PowerHouse 522 with 300W output and 299Wh of storage, and the Anker 536 PowerHouse with 500W output and 508Wh of storage. Both are out of stock at the moment, priced at $339 and $469 when available. Larger and newer models live in our Anker SOLIX range if you need power today.

How to choose a PowerHouse portable generator

• Match output to the biggest single device. A laptop charger draws 60 to 100W, a CPAP without a heated humidifier around 30 to 60W, a small TV about 50W. The 300W PowerHouse 522 covers all of these. A blender, a drone charger array or a mini projector plus laptop is where the 500W Anker 536 earns its place.
• Count the watt-hours you need per day. Charging two phones and a laptop once takes roughly 100Wh. The 299Wh unit gets you through a weekend of that; the 508Wh unit adds room for a camera kit and a fan overnight.
• Look at cycle life, not just price. Both models use LiFePO4 cells rated for 3,000 charge cycles and carry a 5-year warranty. At one full cycle a day that is over eight years of use, so the cheaper unit is not a short-term purchase.
• Ports matter in this class. The 522 has two built-in USB-C ports, which lets you skip the AC inverter and charge phones and laptops more efficiently. Check the port list against your cables before deciding.

Setup and usage tips

• Before buying any Anker portable generator, run your device list through the Solar Kit Calculator. If it returns a battery size above 500Wh, skip this page and look at the SOLIX F3000 or F3800.
• Charge from USB-C where you can. Converting battery power to 120V AC and back to DC in a laptop brick wastes energy; a direct USB-C connection stretches a 299Wh battery noticeably.
• Pair with a small panel for Anker PowerHouse solar charging. A unit this size does not need a 400W array; a compact folding panel keeps it topped up on a sunny campsite.
• Store at partial charge if the unit will sit for months, and top it up every few months. LiFePO4 cells tolerate this well, which is part of why the 10-year design life is realistic.
• Keep the station out of direct sun in a hot car. The 522 monitors its own temperature many times per second, but heat still shortens any battery's life.

Frequently asked questions

Can a PowerHouse power station run a refrigerator? Not for long. A full-size fridge needs more storage than 508Wh and often more surge than 500W. For fridges, look at a 3,000Wh-class Anker SOLIX station instead.

Which one for a CPAP on a two-night trip? A CPAP running without humidification uses roughly 30 to 60W, so 240 to 480Wh over two nights. The 508Wh Anker 536 covers that with a small margin; the 299Wh unit needs a daytime recharge in between.

How long does a PowerHouse portable unit take to recharge? The pack data for these two models does not list recharge time, so we do not quote one. Wall charging is the fastest option; a small panel is for topping up during the day.

When these models come back in stock they ship free to the mainland US with 30-day returns, and the larger SOLIX units are available now. Call us if you are unsure whether a small unit or a full station fits your needs.
