THE SHORT ANSWER
Record the full model number and the field describing the mains input. Preserve its voltage range and frequency. A DC output or battery rating does not describe what can be connected directly to the wall.
Locate the exact model and the relevant component
Inspect the product label, external charger and the official manual. Use the complete number, including suffixes. The marketing family name is often less specific than the model on the label.
For a product with an external power supply, record the supply model separately. If a seller provides another charger, the original charger’s specification no longer verifies the supplied component.
Separate INPUT from OUTPUT
On a power supply, INPUT describes the power it receives. OUTPUT describes the power it supplies to the device. When the input is AC mains and the output is DC, those fields answer different questions.
Do not compare a small DC output number against a country’s mains voltage. Use the full input statement, units and frequency. When the field is unclear, obtain the official document rather than transcribing a guess.
Preserve frequency, selectors and conditions
Keep 50 Hz, 60 Hz and 50/60 Hz as written. Keep any manual selector ranges and the instructions for changing them. A specification with two separate bands is not automatically a continuous range.
The rating label also does not settle local warranty, repair, device language or regional restrictions. These need their own manufacturer evidence. Do not compress the entire decision into one label field.
Build a record you can verify
Use a label photograph to identify the unit, then locate the exact manufacturer manual or support page. A photograph is useful for your own check; JMC’s public conclusions require traceable official evidence.
If the label is damaged, removed, inconsistent with the manual or attached to a modified product, leave the affected fact unresolved. The exact unit must be identifiable before a database result can be applied.
- Full model number and sales-market version.
- Power component and input voltage ranges.
- Input frequency and selector instructions.
- Plug ratings, grounding and official use restrictions.
Rating-label examples
| Example label | What it tells you | What still needs checking |
|---|---|---|
| INPUT 100–240 V ~ 50/60 Hz | Mains input to this component | Its exact model, plug, grounding and restrictions |
| OUTPUT 20 V DC | Power delivered by a supply | The separate mains INPUT field |
| 100–120 V / 200–240 V with a selector | Separate selected input bands | The official switch-position instructions |
| Battery 7.2 V | A battery-related rating | The charger input, charging method and exact battery compatibility |
Illustrative labels, not specifications for a particular product. No compatibility verdict is inferred from these examples.
MOVE FROM GENERAL GUIDANCE TO YOUR MODEL
Check the exact model.
Use the full model number on the unit or charger. Missing evidence is reported as insufficient information.
Search a product name or the full model number. Confirm the exact suffix on the product label, box or manual.
Models with current official facts
These records have enough current evidence for a model page. This list is not a compatibility endorsement.
Questions before use
Should I read the battery voltage as the input voltage?
No. A battery or DC output rating serves a different purpose from a mains-input specification. Identify the component and field first.
Can a photo replace the official manual?
A photo identifies your unit. Official evidence is still needed to verify the specification and its use conditions.
What if the manual and unit label differ?
Do not choose the more convenient value. Clarify the exact version and discrepancy with the manufacturer.
