Introduction#

The CUKTECH 15 Ultra PB200U Power Bank has two USB-C ports and one USB-A port for fast charging and discharging, a colour display, and a button to control it.

You can get 210W output by using all three ports: OUT1 20V/6A, OUT2 20V/3A, OUT3 10V/3A.

Beast Mode is impressive! The power bank supports 165W input by combining two USB-C ports.

The PB200U is pretty big compared to the CUKTECH PB100P that I recently reviewed.

The power bank has a conversion efficiency of 83.33% at 5V/3A.

Battery pack: 14.4 V * 5 Ah = 72 Wh total energy.
USB output: 5 V * 12,000 mAh = 60.0 Wh usable energy.
Conversion efficiency: 60 Wh / 72 Wh = 83.33%

The side of the power bank mentions an Output Capacity of 12,000mAh (5V/3A).

The typical energy is 72 Wh (14.4V*5000mAh), as noted on the power bank, the box and the user manual. This is useful for airlines. That said, the power bank does not have a 3C mark for flying within China.

Mostly Melbourne kindly sent this power bank for review. I have not been paid for this review nor have I held back my opinions of this power bank.

Packaging#

The CUKTECH PB200U comes in a black cardboard box with an image of the power bank on the front and specifications on the back.

The following was included in the box:

• CUKTECH PB200U.
• USB-C to USB-C 6A cable.
• Carry bag.
• User manual.

User Manual#

Powerbank in use#

The colour display has protective film to remove.

Two USB-C ports can be used for input and output, while the USB-A port is for output only.

The power bank can tailstand.

There are lot of details in small writing on the side of the power bank.

There is “70.56/72 Wh AirLine Safe” label on the back of the power bank.

No CCC mark was found. So I could not fly domestically in China with this.

While visiting China, I bought a Silicone Protective Case from CUKTECH to help protect the power bank.

The case is surprisingly packed with features. It has:

• a small cutout with a lanyard,
• a larger cutout for a strap,
• a cutout for the USB ports,
• a cutout for the display, and
• a cutout for the markings.

The base has a “15 ULTRA” label on it.

Cable#

A CUKTECH branded 1m USB-C to USB-C 6A cable with an e-marker chip is included.

My ChargerLAB Power-Z KM003C USB Meter detected the following:

The USB-C plug has 12 pins populated instead of 24.

Ripple#

To measure the ripple I used the VBUS Ripple mode on a ChargerLAB Power-Z KM003C at 1M 25 µS, a ChargerLAB Power-Z SINK240 USB-C Trigger Board a board and an ALIENTEK EL15 electronic load.

To measure the ripple for 20-28V under load I used a WITRN K2 at 2M while using the KM003C to trigger 20V/6A PPS and 28V Fixed.

Ripple with no load#

The lowest ripple is around 4 mVp-p for USB-C OUT1 when the output is 5V/0A.

The highest ripple is around 30 mVp-p for USB-C OUT2 when the output is 15V/0A.

The ripple for USB-C OUT2 is higher than USB-C OUT1.

Standby drain#

I did not notice any significant standby drain.

The power bank displayed 100% after several days of being unplugged and off.

Thermal Images#

I used a Zoyi ZT-R01 IR Thermography Multimeter to take thermal images of the power bank on a silicone mat.

Room temperature: 14 C

The temperature peaked at 38.5 C while charging the powerbank in Beast Mode (160W).

More thermal images with the Thermal Master P3 (get 10% off with code Mcmahon10):

Conclusion#

The CUKTECH 15 Ultra is built like a brick! It is heavy.

The power bank is packed with features.

The display shows you what the power bank is doing.

Each USB port supports multiple fast charging protocols.

Beast Mode allows you to quickly charge the power bank at 165W by using both USB-C ports at the same time.

This is the type of power bank that I take while glamping with a laptop. Pass-through charging from a car charger to the power bank and then to a laptop is handy for working while on the move.

I would recommend a CUKTECH PB100P or a CUKTECH 15 Air if you want something ligthweight and easy to carry while allowing you to quickly charge a device.

Pros:#

• Beast Mode!
• 140W USB-C OUT1.
• 90W USB-C OUT2.
• 33W USB-A OUT3.
• Pass-through charging.
• Low Current Discharge Mode.
• Colour display.
• Simple to use.
• 1m USB-C to USB-C 6A cable with e-marker (50V 5A, 240W EPR).

Cons:#

• No 3C mark.
• Heavy.
