The 5,000mAh gets you home. The 10,000mAh gets you through the day. The 20,000mAh gets you through the week — or through a Stage 6 loadshedding stretch with four family members' phones still alive.
This isn't a top-up bank — it's a reserve. The power bank you pack when you know you won't be near a plug for a while.
Instead of buying multiple small power banks — one for your car, one for home, one for travel — the 20,000mAh replaces all of them with a single, reliable backup.
Need something smaller? The 5,000mAh fits in your pocket. Need a balance of size and power? The 10,000mAh is the everyday carry. This one is for when power matters most.
Why choose this over other 20,000mAh power banks?
✓ True 3-port simultaneous charging — USB-C, USB-A × 2
✓ Li-polymer battery — lighter and safer than equivalent Li-ion units
✓ Simple and reliable — no fast-charge protocol conflicts
✓ Air travel safe — ~74Wh, under the 100Wh IATA limit
For travellers, families, and loadshedding survivors who refuse to watch their devices die one by one.
"Charged four phones over two days of loadshedding without breaking a sweat."
— Thabo N., Johannesburg ⭐⭐⭐⭐⭐
"Took it on a 5-day road trip. My family of three never had a dead phone the whole time."
— Anri V., Pretoria ⭐⭐⭐⭐⭐
| ✦ 20,000mAh · 4–5 phone charges · ✦ 3 simultaneous ports · ✦ 405g · ✦ LED display · Air travel safe · Cable included |
Phones die at the worst possible time — during loadshedding, on the road, or when you need maps, banking, or Uber. This makes sure that never happens.
Real-world use
Stage 4 loadshedding. Three people in the house. Two smartphones, one tablet, all running low.
Plug all three into the 20,000mAh simultaneously. Keep working, keep streaming, keep communicating. Repeat for the next outage — there's still charge left.
Or: a 5-day trip with no reliable power access. One power bank. The whole family stays connected.
What to expect
The 20,000mAh charges at standard 10.5W output — not fast charging. Each connected device charges at standard speed, which is ideal for topping up over hours rather than minutes. Think overnight charging or background charging while you work, not rapid emergency top-ups.
Recharge time: At 10.5W input, expect 10+ hours to fully recharge the power bank itself. Use a wall charger overnight for best results. If you need fast charging, the Xiaomi 67W or 212W power banks in the Portable Power range charge both themselves and connected devices significantly faster.

Why you'll love it
| ✓ | 4–5 full phone charges — enough for days, not hours — a typical 4000–5000mAh smartphone will charge approximately 4 to 5 times from a single 20,000mAh bank (accounting for conversion efficiency). That's a full week of overnight top-ups, a 5-day trip without a wall charger, or multiple family members' phones through an extended loadshedding stretch. |
| ✓ | Three ports simultaneously — the whole group stays charged — USB-C (5V/2.1A), USB-A 1 (5V/2.1A), and USB-A 2 (5V/1A) all active at once. Pass it around the car, the campsite, or the lounge during loadshedding and everyone gets a charge without waiting their turn. |
| ✓ | LED display — know your reserve at a glance — the LED battery indicator shows remaining power so you can plan ahead. With 20,000mAh on hand, you want to know when it's time to recharge it — not be caught by surprise on day 3 of a trip. |
| ✓ | Air travel safe — ~74Wh, confirmed under IATA limits — at approximately 74Wh, the 20,000mAh sits comfortably under the 100Wh IATA carry-on limit. Take it on domestic and international flights in your hand luggage without airline restrictions. As always, power banks must travel in carry-on, not checked bags. |

Frequently asked questions
How long does it take to recharge the power bank itself?
At 10.5W input (5V/2.1A), expect 10 hours or more to fully recharge from empty. The best approach is to plug it in overnight via a wall charger so it's full and ready for the next day. If you need a power bank that recharges quickly, the Xiaomi 67W or 212W can be recharged at up to 65–100W, cutting self-recharge time significantly.
Does it support fast charging?
No — the WINX GO Simple 20,000mAh charges connected devices at standard 5V/2.1A (10.5W). It will not activate fast-charging protocols. At this capacity the value is total charge count and simultaneous multi-device charging, not speed. For fast charging alongside high capacity, see the Xiaomi 67W or 212W in the Portable Power range.
How many phones can it charge at once?
All three ports — USB-C, USB-A 1, and USB-A 2 — can be active simultaneously. The combined output is capped at 10.5W, distributed across connected devices. Three phones charging at once will each charge more slowly than solo, but all three will charge continuously throughout a loadshedding outage.
