Revisamos el cargador portátil.

Revisamos comes from the verb revisar, which often means to check, to inspect, or to review.

In this sentence, it most naturally means we check or we checked, depending on context.

Examples:

• Revisamos el cargador portátil antes del viaje. = We checked the portable charger before the trip.
• Cada semana revisamos el cargador portátil. = Every week we check the portable charger.

Because in Spanish, the nosotros form of some -ar verbs is the same in the present and the preterite.

So:

• revisamos = we check / we are checking or we checked

You usually know which one it is from the context:

• Ahora revisamos el cargador portátil. = present
• Ayer revisamos el cargador portátil. = past

This is very common in Spanish.

El means the. It is used because cargador is a masculine singular noun.

So:

• el cargador = the charger
• un cargador = a charger

The sentence uses el because it refers to a specific charger, not just any charger.

Yes. In Spanish, adjectives often come after the noun.

So:

• cargador portátil = literally charger portable
• natural English: portable charger

This noun + adjective order is very common:

• coche rojo = red car
• mesa redonda = round table

It usually means portable charger. In many contexts, it can refer to a power bank.

Literally:

• cargador = charger
• portátil = portable

Depending on context, a Spanish speaker may understand it as:

• a charger that is easy to carry, or
• specifically a battery pack / power bank

In Spain, both interpretations are possible, but context usually makes it clear.

Portátil has a written accent because the stress falls on the ta syllable: por-TÁ-til.

Without the accent, Spanish stress rules would make you stress it differently. The accent mark shows the correct pronunciation.

So you pronounce it like:

• por-TA-til

This accent mark is about pronunciation, not about changing the meaning.

A simple pronunciation guide is:

reh-bee-SAH-mos el kar-gah-DOR por-TA-til

A few notes:

• r in revisamos is a soft Spanish r
• v in Spanish sounds closer to a soft b
• g in cargador is a hard g, like in go
• stress:
  • reviSAmos
  • cargaDOR
  • porTÁtil

Because the personal a is only used before specific people (and sometimes pets or personified beings), not ordinary things.

Here, el cargador portátil is an object, so you say:

• Revisamos el cargador portátil.

Compare:

• Revisamos el documento. = no a
• Vemos a María. = uses a because María is a person

Yes. That would mean We are checking the portable charger and it emphasizes that the action is in progress right now.

Compare:

• Revisamos el cargador portátil. = We check / We checked / We are checking depending on context
• Estamos revisando el cargador portátil. = We are checking the portable charger

Spanish often uses the simple present where English might prefer are checking.

Revisar is perfectly natural and means to check, inspect, or look over.

Other possible verbs are:

• comprobar = to verify / check
• examinar = to examine
• probar = to test

The nuance changes a bit:

• Revisamos el cargador portátil. = we checked/looked over it
• Probamos el cargador portátil. = we tested it
• Comprobamos el cargador portátil. = we verified that it works / checked it more formally

So revisar is a very good general choice here.
