Quick Answer
The Hota D6 Pro is a dual-channel 1-6S LiPo charger rated for 200W on AC and 650W on DC, and it's the charger we reach for first on the workshop bench. Its one real weakness is the E108 self-check error, a power-on test that fails if a battery is plugged in too early, or permanently on a small number of faulty units.
Why the Hota D6 Pro Earns Its Bench Spot
Most pilots end up owning two chargers: a slow one for home and a small DC one for the field. The Hota D6 Pro does both jobs in one box. Plug it into the wall and it delivers up to 200W across two channels. Hook up a 24V DC supply at the field and that jumps to 650W total, 15A per channel, enough to push a 6S pack hard without the long wait.
The spec sheet covers 1-6S LiPo, LiHV, Li-Ion and LiFe, a colour LCD driven by Hota's scroll wheel, a 5V/2.1A USB port, and a wireless charging pad moulded into the top for your phone. At around 600g it lives on the bench rather than in the kit bag. We rate it because the dual channels genuinely run independently, not as a shared budget like cheaper "dual" chargers that advertise two ports but choke past 100W combined.
It's not flawless, though. The single thing that trips new owners up is the E108 error.
The E108 Error: What It Is and How to Avoid It
Every D6 Pro runs a self-check the moment you switch it on. If a battery is connected to an output port during that self-check, the charger detects an unexpected load and throws E108. The fix, nine times out of ten: power the charger on first, wait for the self-check to finish and the home screen to appear, then plug your pack in. Almost nobody reads the manual before their first charge.
The harder case is a D6 Pro that throws E108 with nothing connected at all. That's a genuine hardware fault, usually a failed balance-port circuit or a damaged output stage, and no power-cycling clears it. We know this because we've had a batch of D6 Pros do exactly that on self-test, and rather than send them back and forth we listed them as the "E108 Error Special" in our bargain bin. The honest version: the E108 isn't always user error, and when it's not, the charger is properly broken.
If yours self-checks cleanly every time, you have a good unit. If it loops E108 with nothing plugged in, stop reseating leads and contact us before you crack it open.
Which Hota Charger Should You Actually Buy?
The D6 Pro is the sweet spot for most pilots, but Hota's range covers every other use case:
| Model | Power | Best for |
|---|---|---|
| D6 Pro | 200W AC / 650W DC, dual ch. | The all-rounder. Our default pick. |
| S6 | 400W AC/DC, dual ch. | Solid alternative if the D6 Pro is out of stock. |
| T6 | 300W DC / USB-PD only | Field charging from a battery or a PD power bank. 93g, pocket-sized. |
| F6+ Ultra | 500W AC / 1000W DC, quad ch. | The workshop charging bank. Charge four packs at once. |
For the pilot with one or two builds, the D6 Pro is what we'd buy. If you charge at the field from a 12V supply or a power bank, the T6 is the one that lives in your kit bag. Running a fleet? The F6+ Ultra charges four packs at once and is the only one here that genuinely replaces multiple chargers. Browse the full line-up in our chargers collection.
FAQ
Q: Is the E108 error dangerous?
No. It's a self-check failure, not a charging fault. The charger refuses to run rather than risk charging through an undetected problem. Power-cycle with nothing connected, then wait for the home screen before plugging in.
Q: Can the Hota D6 Pro charge two 6S packs at once?
Yes. Both channels are independent up to 15A, so you can charge a 6S on channel one and a 4S on channel two simultaneously, drawing from the 650W DC budget. On AC you're capped at 200W total.
Q: What's the difference between the D6 Pro and the S6?
The D6 Pro has higher DC output (650W vs 400W) and the wireless charging pad. The S6 is a touch heavier but slightly cheaper and just as capable for routine 1-6S charging. Skip the D6 Pro's extras if you'll never use the wireless pad.
