The Speedybee Discharger is an fascinating gadget that transforms LiPo or Li-ion batteries into energy sources for any USB gadgets. Whereas it’s known as a discharger, I’d argue it’s extra like an influence adapter. Although it might function a discharger, I consider that’s not its main intent. On this overview, I’ll delve into its efficiency and discover potential makes use of.
Out there for some FPV instruments and tools that may improve your FPV expertise? Take a look at this round-up: https://oscarliang.com/fpv-tools/
The place to Purchase?
You should buy the Speedybee Discharger from:
It comes with a stability extension cable that helps as much as 6S batteries.

Nearer Look
The Speedybee Discharger makes it doable to cost gadgets, together with laptops and smartphones, by way of its USB Kind-C output, from 3S to 6S LiPo or Li-ion batteries. The utmost output energy is determined by the enter voltage, providing as much as 30W for 3S, 40W for 4S, and 60W for 6S LiPo.
Its four-digit LED show showcases enter/output voltage and output present, with two buttons for navigating by way of displayed data. It might probably additionally show a variety of error notifications, with the built-in buzzer, provides customers warning about low voltage and different electrical points.
The enter connector is an XT60.
It additionally has a stability port on the aspect, which displays the voltage of particular person cells. The stability port is just not required for the discharger to work.
Nevertheless, the recessed USB-C port is questionable as it might not accommodate some cables with bigger plugs.
This discharger can cost a variety of gadgets like motion cameras and smartphones.
I even managed to cost my MacBook at 66W (20.1V x 3.28A), barely over its most rated energy of 60W.

It’s additionally appropriate for powering instruments like soldering irons.
Tear down of the system.
Voltage Studying Accuracy
I in contrast the voltage readings from the discharger with these from my calibrated multimeter, discovering them to be intently aligned, inside ±0.05V usually.
| Cell# | Discharger | DMM |
|---|---|---|
| 1 | 3.82 | 3.850 |
| 2 | 3.84 | 3.852 |
| 3 | 3.84 | 3.863 |
| 4 | 3.84 | 3.852 |
| 5 | 3.85 | 3.859 |
| 6 | 3.88 | 3.855 |
| XT60 | 23.0 | 23.15 |
How It Works
The system is easy: plug within the battery and the system you want to cost, and it begins charging robotically.
When the battery voltage drops under a sure threshold, it stops charging and alerts you. Word, it doesn’t stability cells throughout discharge; exceeding a 0.3V distinction between cells may even set off an error and alert.
Quick press the left button to cycle by way of the displayed values: enter voltage, output voltage, and output present. Lengthy press the left button to show the system on or off.
Quick press the proper button to change between and examine the voltage of every cell. Lengthy press the proper button to set a minimal cell voltage (default is 3.80V). An alarm will sound when the voltage reaches the mini voltage, at which level output can be lower off.
Conclusion
Primarily, the Speedybee Discharger is designed for discipline charging of USB gadgets, notably these requiring as much as 60W, like laptops and tablets. Whereas there are different merchandise, just like the Speedybee Adapter 3, which provide USB charging from a LiPo battery at 30W, this discharger fulfills its 60W promise.
You should buy the Speedybee Discharger from:
Nevertheless, its dimension is notable; it’s considerably cumbersome for a 60W adapter. Regardless of this, its utility in offering on-the-go charging options might outweigh its dimension for a lot of customers, making it a useful device for these needing energy in distant places.
