Anker 535 Portable Power

The Anker Anker 535 is ideal for outdoor enthusiasts, RV owners, or those seeking reliable home backup power for essential appliances during outages. If you need substantial power (512Wh capacity) for multiple devices or small appliances (up to 500W AC output) and prioritize long-term durability, safety, and a superior lifespan provided by LiFePO4 chemistry, the Anker 535 is your best choice. Its four AC outlets make it perfect for powering a mini-fridge, laptop, or CPAP machine for extended periods.

Buy EnginStar if...

EnginStar Solar Generator, 300W

The EnginStar Solar Generator is perfect for budget-conscious individuals or casual campers who need a compact, portable power source for basic electronics. If your primary need is to charge phones, tablets, cameras, or power small devices under 300W like a fan or drone for shorter trips, and you appreciate its lower $199.99 price point, this unit is a strong contender. Its 296Wh capacity and multiple USB and DC ports provide sufficient versatility for light-duty, occasional use without overspending.

Frequently Asked Questions

Common questions about this comparison

Which power station is better for extended camping trips?

The Anker 535 is better for extended camping due to its significantly larger 512Wh capacity and 500W AC output, allowing it to power more devices for longer than the EnginStar's 296Wh and 300W.

What is the main difference in battery chemistry between the two?

The Anker 535 uses a LiFePO4 battery, known for its increased safety and longer lifespan (typically 2000-3000 cycles). The EnginStar uses a general Lithium battery, rated for 1000 cycles, offering good performance but less longevity than LiFePO4.

Which power station can handle higher-wattage appliances?

The Anker 535 can handle higher-wattage appliances with its 500W continuous AC output across four outlets, compared to the EnginStar's 300W AC output from two outlets. This makes Anker suitable for more demanding electronics.

How do their USB-C charging capabilities compare?

Both units have one USB-C port. The Anker 535 offers a more powerful 60W USB-C PD output, while the EnginStar's USB-C output is not specified but typically lower for 300W stations.
