6 Hours of WiFi. LiFePO4 Battery. Surge Protection When Power Returns.
✔ Keeps your WiFi on during loadshedding · ✔ Protects against power surge damage · ✔ Works automatically — no setup
No dropped Zoom calls. No buffering. No restarting your router every time Eskom flips the switch. Just plug in once and stay connected — automatically.
55Wh LiFePO4 · 18W · Up to 6hrs router runtime · 744J surge protection · 2,000 cycles · 0.55kg
Most loadshedding solutions focus on what happens when the power cuts. The Surf Simple also protects your devices when the power comes back — with 744 joules of built-in surge protection that guards your router and connected equipment from the voltage spike that Eskom's return often brings.

Why surge protection matters for SA homes
When Eskom power returns after loadshedding, it often arrives with a voltage spike. That spike is one of the most common causes of router and modem damage in South Africa. The Surf Simple's built-in 744 joules of surge protection absorbs that spike before it reaches your connected devices — protecting not just during the outage, but at the moment power returns.
Why LiFePO4 instead of standard lithium-ion?
LiFePO4 (Lithium Iron Phosphate) is the same battery chemistry used in premium solar installations and the larger Gizzu power stations. It handles partial charging far better than standard lithium-ion, carries a significantly lower risk of thermal runaway, and is rated for 2,000 full charge cycles — compared to 300–500 for a typical lithium-ion battery. For a device you leave plugged in permanently, this matters.
Quick compatibility check
✔ Your router power adapter says 12V
✔ Uses a standard barrel connector (most are 5.5×2.1mm or 5.5×2.5mm)
✔ Router + ONU combined draw is under 18W
If yes — this UPS will work perfectly for you.
Perfect for
✓ Keeping WiFi routers and fibre ONUs running during loadshedding
✓ Protecting networking equipment from power surge damage
✓ Work-from-home setups that can't afford dropped connections
✓ Charging phones and low-draw devices via 5V USB
✓ Small offices, home offices, and student accommodation
Why you'll love it
| ✓ | Up to 6 hours of router runtime — outlasts most loadshedding stages — at 55Wh the Surf Simple offers significantly more runtime than smaller router UPS products. A typical WiFi router draws 8–12W; at that draw rate the Surf Simple delivers 4–6 hours of uninterrupted internet. Stage 2 to Stage 6 — covered on a single charge. |
| ✓ | 744J surge protection — guards your devices when power returns — surge protectors are often sold separately as an afterthought. The Surf Simple has 744 joules of surge absorption built in, handling both the outage and the potentially damaging spike that comes with Eskom's return. One device replaces both a UPS and a surge protector. |
| ✓ | LiFePO4 battery — 2,000 cycles of reliable performance — rated for 2,000 full charge cycles to 80% capacity. At one cycle per day (one loadshedding outage), that's over 5 years of daily use. The LiFePO4 chemistry is inherently more stable than standard lithium-ion, handles the partial charging that a permanent-installation UPS experiences, and carries a significantly lower risk of thermal runaway — safe to leave plugged in indefinitely. |
| ✓ | Auto on/off — completely hands-free — the Surf Simple automatically switches to battery when power cuts and back to mains charging when it returns. No buttons to press, no manual switching, no action required. Your router stays on and you carry on. |
| ✓ | Three DC output voltages — covers most routers and low-draw devices — 12V/1.5A for routers and modems, 9V/2A for devices that need a lower voltage, and 5V/2.4A for USB charging of phones and tablets. Check your router's power adapter label — if it shows 12V output, the 12V DC port will power it directly. |
Surf Simple vs 30W Mini DC UPS — which one is right for you?
| Surf Simple | 30W Mini DC UPS | |
| Capacity | 55Wh ✓ | 32Wh |
| Battery type | LiFePO4 ✓ | Lithium-ion |
| Router runtime | Up to 6hrs ✓ | ~3hrs |
| Surge protection | 744J ✓ | ✗ |
| Rated cycles | 2,000 ✓ | Not rated |
| Max output | 18W | 30W ✓ |
| Cable kit included | ✗ — check your router cable | ✓ Full kit |
Simple choice: Choose the Surf Simple for longer runtime, LiFePO4 chemistry, and built-in surge protection. Choose the 30W Mini DC UPS if you need higher wattage output (up to 30W) or want to power multiple DC devices simultaneously with the full cable kit included.

What's in the box
✦ 1 × Gizzu Surf Simple 18W 55Wh LiFePO4 Mini DC UPS — Black
⚠️ No DC cables included. You will need a DC cable that matches your router's barrel connector. Check your router's existing power adapter — the connector size and voltage are printed on the label. Most SA routers use a 5.5×2.1mm or 5.5×2.5mm barrel connector at 12V.

Frequently asked questions
What cable do I need to connect my router?
The Surf Simple does not include a DC cable. You need a DC barrel cable that matches your router's power connector. Check the label on your router's existing power brick — it will show the output voltage (usually 12V) and connector size (usually 5.5×2.1mm or 5.5×2.5mm). Take that information to a local electronics store or search online for the matching cable. Alternatively, the Gizzu 30W Mini DC UPS includes a full cable kit if you'd prefer a plug-and-play solution.
What does 744 joules of surge protection actually mean?
Joules measure the total energy a surge protector can absorb before it needs replacing. 744J is a solid rating for a home networking UPS — it can handle repeated moderate surges (like the ones Eskom generates at reconnection) without degrading immediately. Higher joule ratings absorb more energy; 600J+ is generally considered adequate for home electronics protection in South Africa.
Is it safe to leave plugged in permanently?
Yes — it's designed for always-on UPS operation. LiFePO4 handles partial and float charging much better than standard lithium-ion, and the built-in protection circuit prevents overcharging. Leave it plugged in and connected to your router indefinitely.
Can I power both my ONU and router from it?
Potentially, yes — provided the combined draw stays below 18W. A fibre ONU draws around 3W and a typical router 8–12W, totalling 11–15W — within the 18W limit. However, with only one DC output per voltage level, you would need a DC splitter cable (not included) to run two devices from the same output. Check that both devices use the same voltage before splitting.
