Acebeam E70 Mini vs Olight Baton 4 Pro: What the Spec Sheets Don't Tell You
Disclosure: DanPicks may earn a commission if you buy through links on this page. It does not change the price you pay or what I write. This is a research-based article: I compiled it from manufacturer specs, third-party measurements and public reviews, and I have not tested these products myself. How I review.
Short answer: if you want an EDC (everyday carry) flashlight that runs on one 18650 battery, both of these are good picks. Pick the E70 Mini if you care about color quality and a tail-switch-only design. Pick the Baton 4 Pro if you want magnetic charging and two switches. Ignore the headline lumen numbers on both. They are peak figures that last seconds.
Claimed specs, side by side
These come from the manufacturers’ spec sheets as reported by the sources below. They are claims, not measurements.
| Acebeam E70 Mini | Olight Baton 4 Pro | |
|---|---|---|
| Claimed max output | 2,000 lumens | 1,600 lumens |
| Claimed throw | 153 m (5,875 cd) | 200 m |
| Battery | one 18650 | one 18650, 3,500 mAh |
| Length | 111 mm | 111 mm |
| Weight with battery | 120–124 g (measured by two testers) | 114 g (claimed) |
| Water resistance | IP68 (claimed) | IPX8 (claimed) |
| Charging | USB-C on the included cell | USB-C (3.5 h) or magnetic (4.5 h) |
| Switch | one tail switch | tail switch plus side switch |
| Listed price | about $70 for the light alone (2022 review) | $69.99 (Notebookcheck) |

What testers measured: the E70 Mini
Two independent testers measured the E70 Mini. Both received the light free from Acebeam, and both say so. Their setups differ, so the numbers do not match exactly.
| Turbo output | Claimed | 1Lumen | ZeroAir |
|---|---|---|---|
| At turn-on | 2,000 lm | 1,700 lm | not reported |
| At 30 seconds | 2,000 lm | 1,561 lm | 1,376 lm |
| At 10 minutes | 488 lm | not reported |
- Turbo is a sprint. Output at 10 minutes was about 488 lumens in the 1Lumen test, roughly a quarter of the claim. That is normal for small lights because heat forces them to step down. Treat the maximum as a short burst.
- High mode is the realistic top speed. Claimed 900 lm. Measured at 30 seconds: 721 lm (1Lumen) and 645 lm (ZeroAir).
- Throw roughly matches. 4,500 cd (about 134 m) at 1Lumen and 5,358 cd (about 146 m) at ZeroAir, against a claimed 5,875 cd and 153 m.
- Runtime on Low and Mid is close to the claim. 1Lumen measured 18 h on Low against 19 h claimed.
- Color quality is the standout. 1Lumen measured a color rendering index (how natural colors look) of Ra 97–98. ZeroAir reported the high-CRI claim held up.
- Quirk: you double-click from off to turn it on. Both testers noted it takes getting used to.
What testers measured: the Baton 4 Pro
I could not find a published, independent lumen measurement for the Baton 4 Pro. So I can’t tell you whether it reaches 1,600 lumens or how long it holds it. What I found:
- Notebookcheck’s hands-on test took Olight’s numbers from the spec sheet: 1,600 lm turbo, 600 lm high, 120 lm medium, 15 lm low, 200 m throw. Its beam tests were qualitative, not lab readings.
- The tester said the front gets hot in turbo and the turbo mode heats the head quickly. Olight says its regulator caps the temperature at 45 °C. The tester did not report a measured temperature.
- Practical notes from the tester: the clip is hard to operate with one hand, the knurling can roughen clothing, and neither switch allows quick tactical flashes. The magnetic tail works for mounting on steel and for charging.
Who should buy which
Choose the E70 Mini if you want good color rendering, you like a simple single-switch light, and you can live with an unusual turn-on.
Choose the Baton 4 Pro if you want to charge by magnet, you like a side switch that shows battery status, and you want a slightly lighter body (claimed 114 g).
Skip both if you need a light that stays at 1,000+ lumens for a long time. In a pocket-size light, expect sustained output well below the peak. A larger 21700 light is a better fit.
What I could not verify
- The Baton 4 Pro’s real output and runtime.
- Long-term durability of either light. The tests I found were short, and the E70 Mini tests are from 2022.
- Whether the E70 Mini you buy today matches the 2022 units. Manufacturers change firmware and parts.
When a measured test of the Baton 4 Pro appears, or I get either light in my hands, I will update this article and label it Hands-on.
