The Oraimo PowerBox 400 Vision is a beast of a power bank, packing a massive 40000mAh capacity and 22.5W fast charging. I’ve been using it for a couple of weeks, and it’s become my go-to for keeping my gadgets juiced up during long trips, workdays, and even unexpected power outages.
Let’s examine what makes this power bank stand out, with a nod to what others are saying on the web.
Oraimo PowerBox 400 Design and Build
PowerBox 400 Vision feels like it means business. It’s hefty—because of that huge battery—but Oraimo has managed to keep it sleek with smooth edges and a matte finish that resists fingerprints.
The LED digital display is a game-changer, showing the exact percentage of power left, so you’re never guessing how much juice you’ve got.
I’ve seen some chatter on sites like Jumia Nigeria praising its sturdy build, and I agree—it’s tough enough to toss in a backpack without worrying about scratches or dents. There’s also a built-in LED torch, which came in handy during a late-night car repair. Just double-tap the power button, and you’ve got light.
Oraimo PowerBox 400 Charging Performance
With a 40000mAh capacity, this thing can charge my phone (a 5000mAh battery) about six times over, with room to spare for my earbuds and tablet.
The 22.5W fast charging (supporting PD and QC 3.0) means my devices hit 50% in under 30 minutes, which is clutch when I’m rushing out the door. It’s got four outputs (three USB-A and one Type-C), so I can charge multiple devices at once without a hitch.
Websites like Cellular Kenya highlight its ability to handle family-sized charging needs, and I can see why.
I powered my phones and USB touch light simultaneously, and it didn’t break a sweat. Recharging the power bank itself takes about 12 hours with a fast charger, which is reasonable for its size.
Oraimo PowerBox 400 Key Features
- Clear Digital Display: No vague bars here—just clear numbers telling you exactly what’s left.
- Four Outputs: Charge up to four devices at once, perfect for group trips or heavy users.
- Dual Inputs (Type-C and Micro-USB): Flexible recharging options, though I stick to Type-C for speed.
- Safety First: Oraimo’s AniFast chip keeps things cool and protects against overcharging, which is a major plus.
One minor gripe? It’s not exactly pocket-sized. But for the power it delivers, I’m happy to make room in my bag.
PowerBox 400 Vision is a steal for what it offers. Compared to smaller 20000mAh power banks that cost nearly as much, this one’s ultra-high capacity and fast charging make it a no-brainer for power-hungry users.
Some reviews on Oraimo’s official site mention it lasting weeks on a single charge for light use, and I can confirm it’s a reliable backup for long stretches.
If you need a dependable, high-capacity charger that can keep up with your life, this is it. I’m already recommending it to friends, and I bet you’ll feel the same after a week with it.
