Main trade-off
Brother ADS-1300
The US base box has no AC adapter. USB-A or an insufficient USB-C host needs optional AC power, so the outlet-free case disappears.
Head-to-head
Brother ADS-1300 vs Epson ES-400 II: Brother needs 15 W USB, Epson avoids batch reloads
The short answer
Choose ADS-1300 for eligible small packets when a compatible, permitted computer supplies at least 15 W directly over USB-C through the included cable. USB-A or lower output needs optional AC, absent from the US box. Choose ES-400 II to avoid reloading a 30-sheet packet of flat, dry, same-size loose Letter/A4 paper at 80 g/m² and 0.08 to 0.14 mm each. Its 50-sheet rating exceeds Brother’s 20. Epson needs AC, permitted computer software, open trays and 10 cm rear-wall clearance. At a powered desk with 20 eligible sheets or fewer, neither advantage decides.
Before you choose
The reasoning and the trade-offs
The laptop’s power output decides whether the temporary desk works
An outlet-free temporary desk becomes usable with ADS-1300 only when the computer supports and permits its scanning software and supplies at least 15 W directly over USB-C through the included cable. Use eligible paper, open supports and a clear exit. USB-A or lower output requires optional AC, removing that location advantage. The US box supplies no AC adapter.
What this is based on
The Brother US power article states the output threshold and optional-power fallback for ADS1300. Epson’s guide and safety instructions require its supplied AC hardware. This is an operating requirement, not a battery-runtime or travel-comfort test. Both still need supported paper and clear document travel.
Main trade-off
Epson ES-400 II
Its supplied AC adapter is required even when the computer has a capable USB-C port.
Brother ADS-1300
- Choose it for
- ADS-1300 can work without a scanner outlet when a compatible computer permits its scanning software and supplies at least 15 W directly over USB-C through the included cable. The US box has no AC adapter. USB-A or lower output needs optional AC, losing this benefit. Use eligible paper within its feeder limits, with open supports and a clear exit.
- Main trade-off
- The US base box has no AC adapter. USB-A or an insufficient USB-C host needs optional AC power, so the outlet-free case disappears.
Epson ES-400 II
- Choose it for
- ES-400 II avoids a reload for 30 flat, dry, same-size loose Letter/A4 sheets at 80 g/m² and 0.08 to 0.14 mm each, following feeder rules. Its 50-sheet rating exceeds Brother’s 20-sheet limit. Provide AC, a compatible USB computer permitting Epson software, extended trays and 10 cm rear-wall clearance. At 20 eligible sheets or fewer, this benefit disappears. Completion is not guaranteed unattended.
- Main trade-off
- Its supplied AC adapter is required even when the computer has a capable USB-C port.
About this comparison
Compare Brother ADS-1300 and Epson ES-400 II by 15 W laptop power, paper loading and software access, with the conditions that reverse the choice.
A short packet at a temporary desk and a recurring office pile can interrupt you in different ways. Brother can let a qualifying laptop power the scanner. Epson can let a larger eligible packet finish feeding before you return to load more paper. Start with the real location and originals, since either advantage can disappear.
Winner by situation
Start with what you need it to do
I scan small eligible packets at desks without a convenient scanner outlet
Brother can make this location practical with a compatible computer permitting its scanning software and supplying at least 15 W directly over USB-C through the included cable. Stay within eligible paper and feeder limits, with supports open and exit clear. Its US box has no AC adapter. USB-A or weaker power needs optional AC and removes the outlet-free benefit.
- Brother ADS-1300
- Better fit
- Epson ES-400 II
- Caution
I repeatedly return to reload a suitable thirty-sheet packet
Epson can remove a capacity-driven return for 30 flat, dry, same-size loose Letter/A4 sheets at 80 g/m² and 0.08 to 0.14 mm each within feeder rules. Its 50-sheet rating exceeds Brother’s 20. Allow AC, a compatible USB computer permitting Epson software, extended trays and 10 cm rear-wall clearance. Smaller packets remove this benefit, without implying unattended completion.
- Brother ADS-1300
- Good
- Epson ES-400 II
- Better fit
My fixed desk has power and my packets contain at most twenty eligible sheets
Both can take one eligible load of up to 20 flat, dry, same-size loose Letter/A4 sheets at 80 g/m² and 0.08 to 0.14 mm each. Follow the loading checks. With permitted software, Brother’s direct 15 W USB-C or optional AC and open supports, or Epson’s AC, open trays and 10 cm rear-wall clearance, neither main difference decides.

- Good
There is no AC outlet and my computer cannot provide the required USB-C power
Neither base package meets this computer-scanning setup when no AC outlet is available and the computer cannot supply at least 15 W through a direct USB-C connection. Brother’s lower-output or USB-A route needs optional AC power, and Epson needs its supplied AC adapter. Do not assume that a matching connector or a USB hub supplies the missing power.
- Brother ADS-1300
- Not suitable
- Epson ES-400 II
- Not suitable
The managed computer blocks both scanner workflows
Neither completes the computer-file workflow here if the intended computer blocks both scanners or their required software. Confirm the exact operating system, USB access and permission to install and run the relevant application before buying. Brother’s separate scan-to-USB-drive route does not make the blocked computer workflow work.
- Brother ADS-1300
- Not suitable
- Epson ES-400 II
- Not suitable
My bound or fragile original must remain stationary
Neither base scanner provides a flatbed surface. Use a separately verified flatbed or overhead method suitable for the actual original. A larger feeder, an optional carrier or a working power source does not remove the requirement to keep that original still.

What matters in practice
The differences that matter
The laptop’s power output decides whether the temporary desk works
An outlet-free temporary desk becomes usable with ADS-1300 only when the computer supports and permits its scanning software and supplies at least 15 W directly over USB-C through the included cable. Use eligible paper, open supports and a clear exit. USB-A or lower output requires optional AC, removing that location advantage. The US box supplies no AC adapter.
How we reached this conclusion
The Brother US power article states the output threshold and optional-power fallback for ADS1300. Epson’s guide and safety instructions require its supplied AC hardware. This is an operating requirement, not a battery-runtime or travel-comfort test. Both still need supported paper and clear document travel.
A thirty-sheet packet changes when you return to the feeder
For 30 flat, dry, same-size loose Letter/A4 sheets at 80 g/m² and 0.08 to 0.14 mm each, Brother needs a second load while Epson’s 50-sheet rating covers the initial packet. At a qualifying AC-powered desk, Epson avoids a capacity-driven return. Preparation and file checking remain. At 20 eligible sheets or fewer, this independent loading advantage disappears.
How we reached this conclusion
The example compares published limits for the same ordinary stock. Remove staples and clips, fan and align sheets, fit the guides and allow the required working space. Two loads versus one is a handling calculation. It does not establish faster completed files, fewer jams or safe unattended use.
Sorting the originals can erase the attractive sheet count
Thermal receipts, sticky notes and glossy pages do not become eligible merely by fitting the feeder. Sort the packet before relying on either sheet count, since Brother also restricts mixed thickness and paper quality. Exceptions may require separate handling. If an original must remain bound and stationary, neither base feeder is suitable.
How we reached this conclusion
Each manual distinguishes ordinary sheets from exclusions and special handling. The 20- and 50-sheet figures are not universal capacity guarantees. No total stack-thickness number is invented from a different model’s manual, and no accessory is assumed to be included.
Choice A
Brother, ADS-1300
ADS-1300
A 20-sheet feeder for 80 g/m² plain paper. With the included cable, a direct computer USB-C port supplying at least 15 W can power it. The computer software must be permitted, the paper must qualify and the US box has no AC adapter.
- Best matched use
- ADS-1300 can work without a scanner outlet when a compatible computer permits its scanning software and supplies at least 15 W directly over USB-C through the included cable. The US box has no AC adapter. USB-A or lower output needs optional AC, losing this benefit. Use eligible paper within its feeder limits, with open supports and a clear exit.
Checked facts
- Power away from an outlet: Direct computer USB-C port supplying at least 15 W
- Loading a recurring 30-sheet office packet: Two loads within the 20-sheet rating
- What the sheet count leaves out: Standard stock must be 51.8 to 128 g/m² and 0.08 to 0.14 mm per sheet
- Permission on the actual computer: Permitted USB scanning software, with iPrint&Scan among the documented options
Choice B
Epson, ES-400 II
ES-400 II
A USB computer scanner rated for 50 ordinary sheets at 80 g/m². It needs the supplied AC adapter, permitted software and room for its extended trays plus 10 cm behind it by a wall. Heavier stock lowers its rated load.
- Best matched use
- ES-400 II avoids a reload for 30 flat, dry, same-size loose Letter/A4 sheets at 80 g/m² and 0.08 to 0.14 mm each, following feeder rules. Its 50-sheet rating exceeds Brother’s 20-sheet limit. Provide AC, a compatible USB computer permitting Epson software, extended trays and 10 cm rear-wall clearance. At 20 eligible sheets or fewer, this benefit disappears. Completion is not guaranteed unattended.
Checked facts
- Power away from an outlet: Supplied AC adapter plus USB computer connection
- Loading a recurring 30-sheet office packet: One initial load within the 50-sheet rating
- What the sheet count leaves out: Letter/A4 table permits 27 to 413 g/m² with lower counts as weight rises
- Permission on the actual computer: Permitted Epson ScanSmart and scanner software
Meaningful differences
What changes the fit
| What changes | Brother ADS-1300 | Epson ES-400 II | Why it matters |
|---|---|---|---|
| Power away from an outlet | Direct computer USB-C port supplying at least 15 W | Supplied AC adapter plus USB computer connection | Brother can skip the scanner wall-power connection when the actual host qualifies. A USB-A adapter or lower-output port removes that benefit. Neither connector shape nor a compact body establishes a working power source. |
| Loading a recurring 30-sheet office packet | Two loads within the 20-sheet rating | One initial load within the 50-sheet rating | For flat, dry, uniform 80 g/m² Letter/A4 plain paper, each sheet 0.08 to 0.14 mm thick, Epson avoids one capacity-driven return to the feeder. Preparation, checking and saving still take attention. Heavier stock and unsuitable materials change the example. |
| What the sheet count leaves out | Standard stock must be 51.8 to 128 g/m² and 0.08 to 0.14 mm per sheet | Letter/A4 table permits 27 to 413 g/m² with lower counts as weight rises | The comparison uses one ordinary paper stock so loading counts mean something. It does not turn receipts, glossy photographs, attached notes or damaged pages into eligible office paper. The cited tables do not give a universal millimeter limit for these two complete stacks. |
| Permission on the actual computer | Permitted USB scanning software, with iPrint&Scan among the documented options | Permitted Epson ScanSmart and scanner software | Prepare the supported software before arriving at another desk. Host power does not grant software rights, and an installed app on one computer does not establish access on another. Change saved scan settings only when the job needs it. |
| Space while sheets move | Open top cover and document support arms, with a clear exit | Extend input and output trays, with at least 10 cm behind it by a wall | Measure the operating arrangement on a stable desk, including access to load and collect pages. A storage dimension or product photograph cannot certify the working space. |
What you give up
Every choice has a cost
If you choose Brother ADS-1300
- A suitable 30-sheet packet needs another load. The 20-sheet headline uses 80 g/m² plain paper and does not override individual sheet thickness or material restrictions.
If you choose Epson ES-400 II
- The larger ordinary-paper rating does not promise faster saved files or unattended completion, and heavier or unsuitable paper changes the loading decision.
Recommendation switch
The decision flips if...
A qualifying laptop must power small supported paper jobs away from an outlet
Choose Brother ADS-1300. Outlets cease to decide the scanning spot only if Brother receives at least 15 W directly from a compatible computer over USB-C through its included cable, with permitted software, eligible paper, open supports and clear exit. The US box lacks AC. USB-A or lower output requires optional AC and defeats this advantage.
The recurring interruption is reloading a supported thirty-sheet packet
Choose Epson ES-400 II. Thirty flat, dry, same-size loose Letter/A4 sheets at 80 g/m² and 0.08 to 0.14 mm each favor Epson’s 50-sheet feeder over Brother’s 20. Follow feeder rules, with AC, a compatible USB computer permitting Epson software, open trays and 10 cm rear-wall clearance. At 20 eligible sheets or fewer, loading no longer favors Epson. No unattended-completion guarantee follows.
No AC is available and the host cannot supply at least 15 W directly over USB-C
Choose neither. Neither base package meets this computer-scanning setup when no AC outlet is available and the computer cannot supply at least 15 W through a direct USB-C connection. Brother’s lower-output or USB-A route needs optional AC power, and Epson needs its supplied AC adapter. Do not assume that a matching connector or a USB hub supplies the missing power.
The required computer workflow is blocked, or the original must remain stationary
Choose neither. Neither completes the computer-file workflow here if the intended computer blocks both scanners or their required software. Confirm the exact operating system, USB access and permission to install and run the relevant application before buying. Brother’s separate scan-to-USB-drive route does not make the blocked computer workflow work. If the original must remain bound and stationary, neither base sheet feeder supplies that scanning surface. Use a verified flatbed or overhead arrangement.
What matters in practice
Before you choose
Verify the power and software available at your real scanning spot, then count the eligible sheets in a normal packet.
What this comparison cannot tell you
- The 30-sheet example establishes a loading consequence, not measured scan time, OCR accuracy, image quality, jam rate, laptop battery endurance or unattended completion.
- The plain-paper examples exclude valuable or fragile originals that require a different handling method. Neither base scanner is a flatbed for a bound book or an original that must remain stationary.
- The two purchase reasons are power availability and returning to reload. Moving between desks explains when power matters. It is not counted again as a separate portability advantage.
- Check the exact ADS-1300 or ES-400 II package and the complete cost of any needed accessories before ordering. No current price, seller, stock or offer is asserted.
