For small and medium internet cafés and e-sports venues (80–300 seats),Settings with high-power PCs, monitors and A/C running long hours, offering a complete energy-saving solution based on the Zhijiexin ZX-01 AI Intelligent Power Loss Regulator.
Understand the bill's makeup first to see where the savings are. The table below estimates the electricity makeup of a typical mid-size café (100 seats, ¥15,000/month).
| Equipment type | Monthly usage (kWh) | Monthly bill (¥) | Share | Savings potential |
|---|---|---|---|---|
| 🖥️ PCs (100 units) | 9000-12000 | 7200-9600 | 55-60% | High (non-linear load, low power factor) |
| 📺 Monitors (100 units) | 1500-2000 | 1200-1600 | 9-12% | Medium-high (switch-mode power supply) |
| ❄️ Central A/C / split A/C | 3000-5000 | 2400-4000 | 20-30% | High (inductive load) |
| 💨 Fresh-air system / exhaust | 300-600 | 240-480 | 2-4% | Medium (motor load) |
| 💡 Lighting | 200-400 | 160-320 | 1-3% | Low (resistive load; LED already efficient) |
| 🎧 Network gear / servers | 200-400 | 160-320 | 1-3% | Low (low power) |
| 🔌 POS / surveillance / vending machines | 200-400 | 160-320 | 1-3% | Low (low power) |
| Total | 14,400–20,800 kWh | ¥11,520–16,640 | 100% | The main savings potential is in PCs + A/C |
💡 Key insight:In a café's electricity bill,PCs + monitors + A/C together account for 85–95%. PC power supplies areswitch-mode power supplies (non-linear loads), with a generally low power factor (about 0.65–0.75) and significant harmonics. Add inductive A/C load and the reactive current is very large.This is why internet cafés have huge savings potential—and one of the business types where power savers work best.
Based on mature reactive-power compensation engineering—not some gimmick, just physics.
PC switch-mode power supplies, A/C compressors, fresh-air motors and similar equipment generate large reactive currents when running. Switch-mode supplies also cause notable harmonic pollution. These currents do no useful work but take up line capacity, increase conductor heating, and—for commercial and industrial users—can incur power-factor penalty charges.
The device connects in parallel on the distribution-cabinet busbar and uses AI algorithms to monitor reactive-power levels, harmonics and load changes in real time. It replaces no existing equipment and doesn't affect the café's normal business.
Based on real-time monitoring data, it supplies reactive-power compensation locally to the system—'containing' the reactive current near the compensation point instead of letting it travel back and forth in the lines. Line losses fall, transformer capacity is freed, and the power factor rises above 0.9.
Lower line losses mean less total power is needed to deliver the same active power (= a lower bill). For commercial and industrial users subject to the Measures for Power-Factor Adjustment of Electricity Charges, raising the power factor above 0.9 also directly reduces power-factor penalty charges and, in some cases, earns a rebate.
February vs. January: an average daily saving of about 60 kWh, ~¥17,000/year.
Comparison design:The device was installed on February 5. January had no device (31 days); February had the device (the official accounting period starts February 11, with the first 4 days excluded).Compared over the same hours and similar foot traffic.
Core finding:January averaged 616.5 kWh/day; February averaged 556.7 kWh/day (excluding the first 4 days before installation)—an average daily saving of about 60 kWh. At the local tariff of ¥0.8/kWh, that's ¥48/day.
Savings estimate:about ¥1,440/month,~¥17,000/year saved. With a device investment of a few thousand to over ¥10,000 (for multi-unit parallel deployment),Payback in under six months。

Zhijiexin's recommended configuration:One ZX-01 per ¥6,000 of monthly bill, with multi-floor cafés deployed by floor and multi-zone cafés by zone. The final plan depends on the on-site survey.
💡 Actual savings rates vary with load characteristics, original power factor, tariff plan and other factors. We recommend a free on-site survey first.
5 frequently asked questions about internet-café energy saving.
Mid-size cafés (80–150 seats) usually have monthly bills of ¥12,000–20,000, and large cafés (200+ seats) can reach ¥30,000–50,000.
Electricity is typically 15–25% of a café's revenue. Above 25%, there's significant room to optimize.
It depends on the number of seats, machine specs (high-spec machines use more power), opening hours and A/C intensity.
Internet cafés are one of the business types where power savers work best.
Why:PC power supplies are switch-mode (non-linear) loads with a low power factor and serious harmonic pollution. With many PCs running at once plus inductive loads like A/C and fresh-air systems, the reactive current is very large. Reactive-compensation equipment can substantially reduce line losses.
Real cases:After installing the Zhijiexin ZX-01, Wangjulong Internet Café in Xi'an saved about 60 kWh/day, ~¥17,000/year.
But note: plug-in home power-saver gadgets are a scam—choose professional three-phase 380V cabinet-parallel equipment.
Based on Zhijiexin's real cases: Wangjulong Internet Café saves about ¥17,000/year (on a ¥15,000/month base). Other internet-café cases measured savings of ¥15,000–30,000/year. Payback is typically 4–8 months.
The exact savings amount depends on:(1) the number of seats and machine specs; (2) opening hours and occupancy; (3) the scale of supporting equipment (A/C, fresh-air); (4) the tariff plan.

No closure needed. The Zhijiexin ZX-01 connects in parallel in the distribution cabinet, without changing the existing circuit or affecting the PCs' normal operation.
Installation process:
(1) on-site survey by an engineer (30 min, can be done during business hours);
(2) a brief power-off for wiring (1–2 hours, best scheduled in the 4–6am off-peak window when almost no one is online);
(3) commissioning and a power-factor test (30 min).
The whole process doesn't affect the nighttime peak hours.
Zhijiexin's recommended sizing rule:One ZX-01 per ¥6,000 of monthly bill. A mid-size café with 100 seats usually has a monthly bill of ¥12,000–15,000, so 2–3 ZX-01 units in parallel are recommended.
Configuration reference:
(1) under 50 seats: 1–2 units;
(2) 80–150 seats: 2–4 units;
(3) 200+ seats: 4–6 units.
Multiple units in parallel handle load distribution across floors or zones (e.g. Wangjulong Internet Café uses a distributed layout of 3 upper + 2 lower). Final configuration is confirmed by an engineer after an on-site survey.
