The original Ninja Blast takes about 2 hours to charge fully, and the Ninja Blast Max can take up to 3 hours. Those are Ninja’s own figures, and they matter more than most owners expect, because a flat battery means no smoothie.
Quick answer
Charge the Ninja Blast for about 2 hours and the Blast Max for up to 3 hours, using the supplied USB-C cable. Ninja does not publish a charge time for one blend. A full charge covers several short blend cycles.

How long does the Ninja Blast take to fully charge?
The BC100/BC150 Ninja Blast takes approximately 2 hours, according to Ninja’s Blast FAQ. The owner’s manual also tells you to charge for at least 2 hours to get a full battery.

The Blast Max is slower. Ninja says the BC200/BC250 can take up to 3 hours, per its Blast Max FAQ. Many pages quote one number for both. They are not the same.
| Feature | Ninja Blast (BC100/BC150) | Ninja Blast Max (BC200/BC250) |

| Full charge time | About 2 hours | Up to 3 hours |
| Charging method | USB-C port on back of motor base, 5V/3A supply | Supplied Ninja charging cable |

| Status light | See manual | Flashing green, then solid green |
How long does a Ninja blender take to charge for one blend?
Ninja does not publish a charge time for exactly one blend. The 2-hour and 3-hour figures are for a full battery, not a single smoothie.
You can still make a rough plan. In a Food Network review, the Blast ran seven full 30-second cycles before the battery read low, then two more before it died. That is nine cycles from one charge.
Divide the 2-hour charge by nine cycles: 120 minutes ÷ 9 is about 13 minutes of charging per cycle. Treat that as a planning estimate only. It is not an official figure, and charging may not be perfectly even across the battery.
How many smoothies can a full charge make?
Expect several short cycles, but the number varies. Ice, frozen fruit, long blends, and the model all change it. The Food Network count of nine is one data point, not a promise.
Worked example: one smoothie a day
Say you make one smoothie daily and each takes one 30-second cycle. Using the nine-cycle result, one 2-hour charge could last well over a week. Now add heavy ice and a second cycle for each drink. That could drop you to a few days. Charge on a fixed night, such as every Sunday, and top up before travel.
What charger and power supply does the Ninja Blast require?
Ninja specifies a 5V/3A power supply for the original Blast. Plug the USB-C cable into the charging port on the back of the motor base. The Blast Max uses the supplied Ninja charging cable.
A weak phone brick or a cheap cable may charge slowly or not at all. Use what came in the box where you can.
How can I tell when the Ninja blender is fully charged?
On the Blast Max, the indicator flashes green while charging and turns solid green when full. Those are the patterns Ninja confirms.
- Charging: flashing green (Blast Max)
- Fully charged: solid green (Blast Max)
- Low battery or charging error: check the light pattern in your model’s manual, since I have no confirmed pattern to share
Can I use a Ninja Blast while it is charging?
Ninja says the original Blast can be used while plugged in. It will not charge during a blend cycle, though. Charging picks up again once the blades stop.
That also answers a common question: does the blender charge during a blend cycle? No. A plugged-in blend drains no extra charge into the battery, so it is no shortcut to a full battery.
What should I do if my Ninja Blast is not charging?
- No light or no charge? Push the USB-C plug fully into the port on the back of the base.
- Slow charging? Switch to a 5V/3A power supply and the supplied cable.
- Still stuck? Try another outlet and cable, and make sure the blender is not mid-blend.
- Nothing helps? Contact Ninja support.
