3 external batteries with which to survive a blackout

The pandemic has changed us all forever. Until March 2020, we were all very used to not missing anything. That year we began to see how the shelves of our supermarkets were emptied due to the stoppage of business activity. Things picked up, but a year later, we started experiencing a supply crisis, and we saw energy getting more expensive. And this 2022 is going the same way. The invasion of Ukraine and sanctions against Russia have pushed up the price of energy even more, adding to the psychosis that began last year over a possible blackout. For the same reason, some manufacturers are beginning to produce large-capacity batteries for home use.

3 external batteries with which to survive a blackout

Let’s not go to such an extreme case. No blackouts or the end of the world. Suppose we camp in the middle of nowhere and have no access to electricity. Or that we go to a country house for a weekend and have constant power outages. Are there already batteries powerful enough for us to lead a normal life?

Anker 757 Powerhouse

Anker has surprised us these days with this ambitious proposal. It is a huge 1,229 Wh battery , the equipment with the highest capacity they have manufactured to date. It is a compact and quite heavy battery, since lithium iron phosphate (LiFePO4). This technology makes the battery charge faster and degrade less. Anker promises 3,000 cycles without losing capacity and an average lifespan of 50,000 hours.

With a single charge you could power an electric iron for almost an hour or a refrigerator for about 3 and a half hours. To recharge, the brand has its own solar panels that you can also purchase. This model is already available in the United States and is sold for about 1400 dollars.

On Amazon you can find the cheapest model with a capacity of 256 Wh.

Around the same price, the Bluetti battery offers a capacity of 2,000 Wh , and has an inverter that can give an output of 4,800 watts. The battery is also LiFePO4 and the brand promises 3,500 cycles before we begin to notice a loss of capacity. It can be recharged with an outlet and with panels simultaneously.

This battery can be purchased with the BLUETTI PV350 solar panel . To maximize battery capabilities, you can connect two of these panels together and hit the maximum input of 700 watts.



This latest proposal finished its funding process on Indiegogo a couple of months ago. It has a maximum capacity of 2,074 Wh and can be recharged by 80% in just one hour . It reaches 100% in just an hour and a half, well above its competitors.

It can be recharged in 6 different ways and allows you to connect a pair of 300-watt solar panels in parallel. According to this manufacturer, the battery would give us to cook for more than an hour on an induction hob, 32 hours of autonomy for a small refrigerator, one hour of use for a mechanical saw or even to keep an LED light on for about 200 hours.
