Power banks are the trade show giveaway that travels home, onto desks, and into laptop bags. The Anker 321 is compact enough to pocket, useful enough for daily carry, and the flat center face gives your logo a clean, uncluttered stage every time someone reaches for a charge.

At just over 4 ounces, this isn't the gift that gets left at the hotel. The dual-port setup lets a colleague borrow it without unplugging anything, and Anker's built-in safety stack means nobody thinks twice about tossing it in a bag next to their laptop.

• 5,200 mAh charges an iPhone 13 from dead to full once. That's a full conference day covered without hunting for an outlet.
• USB-A and USB-C ports run simultaneously at 12W total, so two devices charge at once and nobody has to negotiate.
• Multi-layer safety protection guards against overcharging, overheating, and short circuits, removing any liability concerns for bulk gifting.
• At 4.16 oz, it slips into a jacket pocket or a welcome kit envelope without adding bulk or weight.
• Charges Bluetooth headphones and portable speakers without overcharging low-draw devices, making it useful across the whole team's gear.
