20,000mAh · 22.5W QC3.0 · 20W USB-C PD · LCD display · 396g · Air travel safe
The Simple 20,000mAh charges slowly. The Fast 2 10,000mAh runs out faster. The Fast 2 20,000mAh doesn't make you choose — maximum capacity, maximum speed, in one bank.
During loadshedding, this is the difference between staying connected and going offline.
The top of the WINX GO range. Not because it costs the most — because it does the most.
For a small premium over the Simple 20,000mAh, you get fast charging on every port, an LCD screen instead of LED dots, and fast self-recharging when you plug it back in overnight.

For frequent travellers, families, and loadshedding households who won't settle for slow charging on a large power bank.
"Charged four phones over two loadshedding days — and they all charged quickly. Didn't even notice it was slow."
— Sipho M., Johannesburg ⭐⭐⭐⭐⭐
"Took it on a week-long trip. Fast-charged my phone every morning. Never ran out."
— Riaan V., Cape Town ⭐⭐⭐⭐⭐
| ✦ 22.5W QC3.0 · 20W USB-C PD · ✦ 20,000mAh · ~4–5 charges · ✦ LCD display · ✦ 396g · 3 ports · Air travel safe |
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 — and when you do plug in, your phone is back to full in half the time of a standard power bank.
Real-world use
Stage 4 loadshedding. Three phones in the house, all running low.
Plug all three in simultaneously. Because each port supports fast charging, each phone charges meaningfully faster than on a standard power bank — not just slow trickle charging through the night.
Next morning: all phones full. Power bank still has charge for two more cycles.
Important to know
Single port fast charging: 22.5W (USB-A) or 20W (USB-C) when used alone. Combined output caps at 15W when multiple ports are active — fast charging speed reduces when ports are shared. For maximum speed, use a single port at a time.
Fast charging requires compatible devices: QC3.0 or USB-C PD. Standard phones charge at standard speed. Most Samsung, iPhone 15+, and modern Android flagships are compatible.
Self-recharge: Both Micro USB and USB-C inputs support fast charging (9V/2A), so the power bank itself recharges significantly faster than a standard input. Use a wall charger overnight for best results.

Why you'll love it
| ✓ | 20,000mAh + 22.5W — the combination no other WINX GO offers — the Simple 20,000mAh has the capacity but charges at 10.5W. The Fast 2 10,000mAh charges fast but has half the capacity. This is the only unit in the range that gives you 4–5 full phone charges and fast-charges each one. It's the uncompromised option. |
| ✓ | 22.5W QC3.0 — fast charging across the full 20,000mAh — every charge cycle delivers up to 22.5W via USB-A (QC3.0) or 20W via USB-C (PD). A compatible phone at 10% can hit 50%+ in 30 minutes — even when you're pulling from a 20,000mAh reserve. |
| ✓ | LCD real-time display — know your reserve precisely — with 20,000mAh on hand, knowing exactly how much remains matters. The LCD shows a live percentage, not vague LED dots. Plan ahead on multi-day trips without guessing how many charges you have left. |
| ✓ | Fast self-recharging — tops up overnight, not over two nights — both USB-C and Micro USB inputs support 9V/2A fast charging, so the power bank itself recharges significantly faster than a standard 5V/2A input. Plug in overnight and it's ready for the next day — no waiting across two nights to have a full bank. |

Frequently asked questions
Does the 15W combined cap affect real-world use much?
In practice, most people charge one device at a time — especially when fast charging matters. The 15W cap only applies when two or three ports are simultaneously active. For single-device fast charging, the full 22.5W (USB-A) or 20W (USB-C) is available. If you're charging three phones overnight during loadshedding, all three will charge — at distributed rather than individual maximum speeds.
