En mi cuarto tengo una regleta porque un solo enchufe no me basta para el portátil y la lámpara.

Both are correct. Starting with En mi cuarto puts the location first, a bit like saying In my room, I have a power strip.

Spanish often moves elements around for emphasis or flow. Here:

• En mi cuarto tengo una regleta = slightly highlights in my room
• Tengo una regleta en mi cuarto = more neutral word order

So this is mainly about emphasis, not a grammar difference.

Here cuarto means room. In many contexts, cuarto and habitación can both mean room.

A few nuances:

• cuarto is very common in everyday speech
• habitación can sound a bit more neutral or slightly more formal
• In Spain, mi cuarto often means my bedroom/room

So En mi cuarto sounds very natural.

In Spain, regleta usually means a power strip or multi-socket extension block.

It is the thing you plug into one wall socket so you can connect several devices.

Depending on the country, English speakers might call it:

• power strip
• extension block
• sometimes extension lead if the cable is emphasized

In Spain, regleta is a very normal word for this.

Because tengo means I have, while hay means there is/there are.

Compare:

• Tengo una regleta = I have a power strip
• Hay una regleta = There is a power strip

Since the speaker is talking about what they personally have in their room, tengo is the right choice.

Because porque is the form used to give a reason: because.

Compare:

• porque = because
• por qué = why
• el porqué = the reason
• por que = a less common combination in other structures

So here:

• Tengo una regleta porque... = I have a power strip because...

Un solo enchufe means a single socket/outlet or just one socket.

The word solo here means only / just one. So the idea is:

• un enchufe = a socket/outlet
• un solo enchufe = only one socket/outlet

It emphasizes that one socket is not enough.

It can mean either, depending on context, which can confuse learners.

In this sentence, enchufe means wall socket / power outlet, because the speaker says one of them is not enough for both devices.

Useful distinction:

• enchufe = plug or socket, depending on context
• enchufar = to plug in

Here, un solo enchufe no me basta clearly points to one wall outlet isn’t enough.

Bastar means to be enough / to suffice. It often works with an indirect object, showing for whom something is enough.

So:

• me basta = it is enough for me
• no me basta = it is not enough for me

In this sentence:

• un solo enchufe no me basta = one socket isn’t enough for me

The me does not mean myself in the English reflexive sense. It marks the person affected: for me.

Yes. Both are possible, but they sound a little different.

• Un solo enchufe no me basta = very natural, compact, common
• Un solo enchufe no es suficiente para mí = also correct, a bit more explicit

The version with bastar is especially natural in everyday Spanish when talking about whether something is enough for someone.

Because portátil here is short for ordenador portátil, and ordenador is masculine.

So even when ordenador is omitted, the article stays masculine:

• el ordenador portátil = the laptop
• el portátil = the laptop

In Spain, portátil is a very common way to say laptop.

Because one para can apply to both nouns together.

• para el portátil y la lámpara = for the laptop and the lamp

This is exactly like English: for the laptop and the lamp.

You could repeat it, but it is unnecessary:

• para el portátil y para la lámpara

That is grammatical, but less economical unless you want extra emphasis.

Because they are two different nouns, each with its own gender:

• el portátil = masculine
• la lámpara = feminine

Spanish normally keeps the article with each noun in this kind of coordination, especially when the nouns have different genders.

So el portátil y la lámpara is the natural form.

Yes, but the tone changes slightly.

• cuarto = room; very common and everyday
• habitación = room; neutral, slightly more formal
• dormitorio = bedroom; more specific

So:

• En mi cuarto... = very natural, personal
• En mi habitación... = also correct
• En mi dormitorio... = correct if you specifically mean the bedroom

Modern standard Spanish usually writes it as solo, without an accent.

Older spelling, or some writers for clarity, may use sólo when it means only, but the current general recommendation is:

• solo = both alone and only, with context making the meaning clear

In un solo enchufe, there is no real ambiguity, so solo without an accent is normal.
