Each battery comes with a charger, a manual, and a few adapter cables.

...

Carefully observing the surface of all the energy storage batteries, and confirming there were no scratches, dents, or watermarks, estimating they were without any damage, Chen Zhou directly flipped open the manual.

Energy storage batteries and solar panels can indeed be used together, but only if they are compatible with each other; if by any chance they are not compatible, the batteries can only be used as disposable ones.

Once tricked by the Space-Time Administration Bureau, Chen Zhou is now "once bitten, twice shy," and dare not be too happy too soon.

...

In terms of capacity, these energy storage batteries each have a capacity of 4 kilowatt-hours, totaling 16 kilowatt-hours, which is already quite a lot for Chen Zhou personally.

Looking further, the first point that surprised Chen Zhou appeared.

The energy storage batteries have built-in bi-directional inverters, plug and play, no need for a separate inverter.

Also, the plugs are very diverse, whether it's a 220V 3000W interface, a 27W QC interface, a 10W 5V2A USB interface, a 30W Type-C interface, or a 60W DC interface, all are available.

All the appliances Chen Zhou currently has can be charged with this energy storage battery.

Moreover, with a 220V interface, not only his existing appliances but also any others that might be delivered in the future, the energy storage batteries can essentially meet the demand.

Marveling at the advancement and convenience of modern technology, Chen Zhou hurriedly turned to the charging method page to see how the energy storage battery charges.

The result also satisfied him.

This energy storage battery supports wireless charging, household socket charging, and solar panel charging.

Although the power of his two solar panels is not high, it's enough to charge the batteries, at most just slower charging speed, which is not a disadvantage for him.

It's already this good, what more could you want?

...

Delightedly moving all the energy storage batteries into the deepest part of the storage room, placing them at the bottom of the sturdiest wooden shelf.

It's still the rainy season, overcast and rainy every day, so the solar panels can't be used temporarily. After mid-April, when the dry season arrives, he'll be able to use electricity recklessly.

Before leaving the storage room, Chen Zhou specially checked the remaining charge of the four energy storage batteries.

Except for one battery with less than sixty percent charge, the other three batteries were around eighty percent.

According to the manual, a new energy storage battery, once fully charged, can charge a phone 272 times, power a chainsaw for 2 hours, or run a 120W refrigerator for 25 hours.

If used on his electric shaver, it could charge over 500 times, with a single battery being enough for him to comfortably shave his beard for two years.

However, Chen Zhou is still clear about where the precious electricity is most cost-effective.

Before confirming that the solar panels can charge the energy storage batteries, he doesn't intend to waste the valuable electricity, even if it really is troublesome to shave with a razor.

...

The arrival of the energy storage batteries made Chen Zhou particularly look forward to the dry season.

Ever since acquiring this batch of treasures, he fantasizes every day about the sight of the solar panel charge controller connected to the energy storage batteries.

Not just once, in his dreams, he sees the numbers on the energy storage battery display slowly ticking upwards, from 78 to 79.

Similarly, not just once, he dreamt of the energy storage batteries showing no reaction after being connected to the solar panels.

For Chen Zhou, every day of April became especially torturous.

He tries to adjust his mindset while attempting to focus his energy elsewhere, like continuing to write textbooks for the indigenous people, or fishing, forging, or making wooden models.

But one cannot entirely deceive one's inner heart.

Chen Zhou had to admit, under the immense temptation of stepping into the electrical age, he still became a toy for the Space-Time Administration Bureau.

Sometimes thinking about how eager and agitated he is, Chen Zhou can't help but feel like a monkey eyeing a banana.

But he thought, if the banana is truly large and sweet enough, and if he could really enjoy it, then temporarily being a monkey is nothing to be ashamed of.

...

As the rainy season was nearing its end, the days of rain gradually decreased.

Taking advantage of the occasional sunny weather, Chen Zhou led the indigenous people in completing several small projects.

The first project was to build a more spacious, sturdier, and more aesthetically pleasing house for the herder indigenous people.

When the dry season comes, and Chen Zhou and the indigenous people return to the factory to work, leaving the herder alone to take care of the flock and two cattle, it certainly wouldn't do to let him continue living in that shabby little house.

Moreover, the milk of the sheep and cattle also needs a more sanitary place for storage.

Chen Zhou hopes the herder can achieve self-sufficiency in a place far from the crowd.

Therefore, not only did he build a new house for the herder, but he also had other indigenous people help the herder open a small vegetable garden in front of his house.

The rice, wheat, and barley in the herder's home don't need to be cultivated by himself, and vegetables like peppers, tomatoes, carrots, onions, and garlic can be self-cultivated by him.

It's just that there's no water source near the hillside, so irrigating the vegetable garden requires carrying buckets of water from the mountain stream.

Chen Zhou thought, since they had already solved so many difficulties for the herder, leaving one problem of fetching water for him to handle shouldn't be a big deal.

Anyway, the herder has to drive the flock and the two cattle to the mountain stream to drink water every day; on the way back and forth, stopping and resting occasionally, the two buckets of water he carries should suffice, after all, it's just vegetables for one person to eat.

If the cattle and sheep breed to a large scale in the future and the herder has no time to fetch water, Chen Zhou plans to dig a reservoir for him.
