Your phone dies at the worst moments. Your laptop battery gives up mid-presentation. Power outages leave you sitting in the dark scrolling through a phone at 5% battery. Generic power banks help a little but they barely charge your phone twice before needing a recharge themselves. The Anker PowerCore Reserve changes the game with 60,000mAh of capacity that can charge an iPhone 17 over ten times. Amazon just dropped this powerhouse to $79, down from $149, hitting an all-time low price that costs barely more than a no-name 10,000mAh power bank.

The Battery Technology That Lasts a Decade
The power bank uses LiFePO4 battery types. Although it may sound complicated, it’s actually very important: In normal Li-ion batteries used by those cheap power banks that last only a year at most, the charging cycle ends at 500 to 1,000 cycles. The power bank from Anker uses 3,000 cycles: That’s three thousand charging cycles or complete discharge cycles before the battery’s capacity reaches 80%. That’s around a decade of normal life.
The true advantage of LiFePO4 over a standard lithium ion battery is more than endurance: This form of battery prevents thermal runaway. In technical terms, LiFePO4 prevents overheating of a battery that eventually leads to it exploding in a fire. The high temperature tolerability of LiFePO4 ranges from –4°F to 140°F which makes it ideal for winter camping or summer road travel.
The 192Wh battery capacity translates to 60,000mAh with a cell voltage of 3.2V. The battery provides enough power to charge a MacBook Air 2.9 times or power an LED light of 3 watts for 42.3 hours. The LED power duration comes in handy during prolonged power outages of several days when you may require constant illumination without having to recharge smartphones. The power bank comes with four charging ports: These include two charging sockets of 27W and 60W through the USB C charging sockets.
The XT60 input port supports the connection of solar panels with a capacity of up to 60W: The Anker power station can now become a sustainable off-grid power solution (the solar panels are not included). The power station takes around four hours to recharge with a 60W USB C wall charger.
The digital smart display takes over the face of the front panel and comes with information such as battery life, input power level, output power level, and estimated remaining life. This provides real-time data that helps you determine perfectly the amount of power being used and the remaining life based on current power levels. No need to guess whether you’ll have enough power to last the night.
The device measures 4.59 inches wide, 4.59 inches deep, and 8.17 inches high: That’s comparable in size to a large water bottle. Weighing 5.1 pounds makes it heavy enough to be substantial but light enough to throw into a backpack or emergency kit. The green cloth exterior provides good traction that won’t slide off and comes with a flat-folded handle.
For $79 for a 60,000mAh LiFePO4 power bank that can recharge from the sun’s power, you’re paying pennies – 0.001 per milliamp-hour. That’s a fraction of what each power bank on the market costs.
