Energizer Ultimate 27000mAh Power Bank – 140W

Energizer Ultimate 27,000 mAh Power Bank – 140W

The Energizer Ultimate power bank model XP27000PD is a high-capacity, high-output portable charger designed to power up laptops, tablets, phones, and more. It supports fast charging via USB-C and USB-A ports, has safety protections, and is rated for airline travel in terms of watt-hours.

Features

• Capacity: 27,000 mAh (99.9 Wh) battery, which is at the upper limit allowed for air travel without special permissions.

• Power Output: Up to 140W maximum total output, enough to charge or support laptops and ultrabooks.

• Ports:
  • Two USB-C PD ports (both bidirectional input/output). One can deliver up to ~100W, the other up to ~30W.
  • One USB-A port for legacy devices / accessories.

• Input / Charging: USB-C ports accept various voltages (5V, 9V, 12V, 15V, 20V, 28V at appropriate amperages) so you can recharge the power bank itself relatively quickly.

• Safety & Management: Includes built-in protections: overcurrent, overcharging, short-circuit protection, etc. Energizer’s “PowerSafe” or similar safety management.

• Display & Indicators: Smart battery level / charge status display (digital) so you can see remaining capacity.

• Device Charging Options: Can charge multiple devices simultaneously (e.g. two USB-C + USB-A) though max combined power is limited by the 140W total.

Benefits

• Very High Capacity: With 27,000 mAh, can power a smartphone many times, or provide a full or near-full charge to tablets and smaller laptops.

• Laptop Friendly: Because of the high PD output (≈100W on one port), it can power many ultrabooks or charge them.

• Fast Charging: Supports high wattages so reduces charging time for compatible devices.

• Versatility: Many ports, multiple devices at once, compatibility with a wide range of devices (phones, tablets, laptops).

• Travelable: Its capacity is within the limit allowed on flights (99.9Wh), so you can carry it onboard.

Limitations / What to Watch Out For

• Weight & Size: As a high-capacity power bank with high output, it tends to be relatively bulky and heavy compared with smaller ones.

• Full Load Efficiency: When charging several devices or drawing full wattage, battery will drain faster and internal heating could be more.

• Charging Time: Even with high input voltages, filling up such a large battery from near zero will take some time, depending on the charger used.

• Compatibility: To benefit from the highest wattage (e.g. 100W from USB-C), the device being charged must support those PD levels; else you get less.

Q&A Section

Q: Can this charger power my laptop?
A: Yes. Because one USB-C port provides up to ~100W, it can charge many laptops (especially ultrabooks) that require ~60-100W.

Q: How many devices can I charge at once, and what power do they get?
A: You can use multiple ports simultaneously (USB-C1, USB-C2, USB-A). For example, one common combination is USB-C1 + USB-C2 giving 100W + 30W, or USB-C1 + USB-A for 100W + 30W. The total never exceeds 140W.

Q: Is this safe to bring on flights?
A: Yes, since it’s 99.9Wh, it is within the typical airline allowance for carry-on power banks (usually up to 100Wh without needing special approval).

Q: How long will it last on a phone / tablet?
A: Depends on device battery size. Rough examples: several full charges for a phone; maybe one full charge for a small laptop or ultrabook. Also depends on how much power the device draws and how many devices are charging.

Q: What kind of charger should I use to recharge the power bank fast?
A: Use a charger / USB-C PD adapter that supports the higher input voltages (20V or 28V) and sufficient amperage (e.g. 5A or whatever spec says). A high-wattage PD charger will recharge much faster.
