BlitzWolf BW-P23: Power Bank Capacity, Output and Practical Features
The BlitzWolf BW-P23 has a capacity of 14,000 mAh when expressed at 3.7 V and can deliver up to 100 W through USB-C. That means it can charge a compatible laptop as well as phones. The power bank itself accepts up to 45 W through USB-C and shows charging information on a TFT display.

That means it can charge a compatible laptop as well as phones. The power bank itself accepts up to 45 W through USB-C and shows charging information on a TFT display.
Capacity and cells
Inside are four LG 18650 lithium-ion cells, each with a capacity of 3,500 mAh. They are connected in series, giving the pack a capacity of 3,500 mAh at the 14.8 V stated on its label. Expressed at 3.7 V, that is equivalent to 14,000 mAh, or approximately 51.8 Wh of energy.
Not all of that energy reaches the device being charged: some is lost during voltage conversion and charging. The quoted examples suggest up to three charges for an iPhone or approximately two for a Samsung Galaxy S24 Ultra. These are estimates; results depend on the model, the battery’s starting charge level and charging losses.
The power bank can also charge a MacBook Air. However, its nominal energy is 51.8 Wh and some is lost during charging, so a full charge from an empty laptop battery cannot be guaranteed.
Up to 100 W USB-C output and 45 W input
The USB-C output delivers up to 100 W, providing enough power for compatible laptops, including the MacBook Air, as well as smartphones. Actual output depends on the device and cable used; the maximum rating does not mean every device will draw that much power.
The USB-C input supports up to 45 W when recharging the power bank itself. A suitable charger and cable are needed to use the maximum input power.
Quoted charging-speed examples include bringing an iPhone to 65% in approximately 30 minutes and adding more than half a MacBook Air battery’s capacity in the same time. Without specific models and charging conditions, these figures cannot be assumed to apply in every situation.
Two ports and a TFT display
USB-C and USB-A allow two devices to charge at the same time, such as a smartphone and a tablet. USB-A is useful for accessories with older cables, while USB-C can be used for compatible higher-power devices. The available information does not specify how power is shared when both ports are in use, so the USB-C port cannot be assumed to deliver the full 100 W in that situation.
The integrated TFT display shows current power, energy input and output, charging time and battery percentage. This lets users monitor how much charge remains and what is happening during charging.
Dimensions and travel use
The power bank measures 140 × 44 × 34 mm and weighs approximately 330 g. It fits in a backpack or bag, though its weight is worth considering for everyday carrying.
It may switch off automatically after a while when power draw is below 1 W. This can limit charging for very low-power devices such as Bluetooth earbuds or fitness trackers.
Who is the BW-P23 for?
The BW-P23 makes sense for someone who wants one power bank for a phone and a compatible laptop and values the information shown on its display. Its strengths are the 100 W USB-C output and the ability to connect two devices at once. Buyers should also account for its approximately 51.8 Wh capacity before losses and the possibility of shutoff at very low power draw.
