A good power bank survives lectures, travel, and lights-out evenings. A bad one is a heavy brick with fake capacity.
What Actually Matters
| Spec | What to look for |
|---|---|
| Capacity | 10,000–20,000 mAh for daily carry; 20,000+ for travel |
| Output | USB-C PD / 18W+ if your phone supports fast charge |
| Ports | At least one USB-C; dual ports if you share |
| Safety | Overcharge protection; reputable brand, not “50,000 mAh” mystery packs |
| Weight | Pocketable vs bag-only |
Ignore absurd mAh claims on ultra-cheap no-name packs — real energy is limited by physical size and battery chemistry.
Buyer Tips for Ghana
- Buy from shops that accept returns / have receipts
- Prefer brands with local service awareness (Anker, Baseus, Oraimo, Xiaomi ecosystem accessories, etc.) — verify current stock
- Check cable quality separately; many “kits” ship weak cables
- For overnight trips, 20,000 mAh + USB-C PD is the sweet spot for most phones

FAQ
Can I take a power bank on a plane?
Yes within airline/Wh limits — usually under ~100Wh for cabin. Don’t pack damaged/swollen banks.
Why does my bank charge slow?
Cable, phone negotiation, or bank output too weak. Try the bank’s USB-C port and a known-good cable.
