wǒ de chōngdiànqì kěnéng fàng zài gōngsī le, shǒujī kuài méidiàn le.

的 marks possession, like 's or of in English.

• 我 = I / me
• 我的 = my
• 充电器 = charger

So 我的充电器 means my charger.

In Mandarin, this is the normal pattern:

• 我 的 手机 = my phone
• 他 的 公司 = his company
• 老师 的 书 = the teacher's book

With close relationships or very common personal nouns, 的 is sometimes omitted, but with something like 充电器, keeping 的 is standard.

充电器 means charger.

It is made of:

• 充电 = to charge / recharge
• 器 = device / tool / instrument

So literally, 充电器 is a device for charging.

In everyday speech, it can mean:

• a phone charger
• a laptop charger
• another charging device

If you want to be more specific, you can say:

• 手机充电器 = phone charger
• 电脑充电器 = computer/laptop charger

可能 means maybe / possibly / probably, and it usually comes before the verb phrase it modifies.

So:

• 可能放在公司了 = might have been left at the company / may be at the office

The basic word order is:

subject + 可能 + verb phrase

Examples:

• 我可能忘了。 = I may have forgotten.
• 他可能在家。 = He may be at home.
• 钥匙可能在车里。 = The keys might be in the car.

In your sentence, 可能 tells us the speaker is not certain.

Yes, 放 literally means to put / place / leave, and here it suggests left behind or placed somewhere.

• 放在 + place = put/leave something in a place

So:

• 放在公司 = left at the company / put at the office

In English, we often say I left my charger at work, even if we do not mean we intentionally placed it there. Chinese can also use 放在 this way, especially in casual speech.

That said, many learners notice that another verb is also common:

• 忘在公司了 = left it at the office by forgetting it there

This version makes the idea of forgetting more explicit. So both are possible, but:

• 放在公司了 = it was left at the office / it's at the office
• 忘在公司了 = I forgot it at the office

在 here introduces the location of the action or result.

Pattern:

放在 + place = put/leave something at/in a place

So:

• 放在桌子上 = put it on the table
• 放在包里 = put it in the bag
• 放在公司 = leave it at the company / office

This 在 is similar to at / in / on depending on context.

Literally, 公司 means company. But in real usage, it often refers to someone's workplace, so it can sound very natural as the office or work in English.

So:

• 在公司 can mean at the company
• but in natural English translation, it is often at the office or at work

This is a case where the most natural English translation is not always the most literal one.

This 了 is a sentence-final particle for the first clause, not something that belongs to 公司 itself.

Clause:

我的充电器可能放在公司了。

Here, 了 helps show a new situation, realization, or updated state. It often appears when the speaker has just come to a conclusion or is reporting a current situation with present relevance.

So the feeling is something like:

• Looks like my charger is at the office.
• I think I left my charger at work.

Without 了, the sentence can still be grammatical in some contexts, but it may sound more neutral or less like a realization.

This second 了 also marks a change of state.

• 没电 = have no battery / be out of power
• 没电了 = has run out of battery / is now out of power

So:

• 手机快没电了 = the phone is about to run out of battery

The 了 here is very common because running out of battery is a change in condition.

Compare:

• 手机没电。 = The phone has no battery. (plain statement)
• 手机没电了。 = The phone has run out of battery / is now dead. (change of state)

快 here means soon / almost / about to.

Pattern:

快 + verb/adjective + 了

This often means something is about to happen.

Examples:

• 快下雨了。 = It's about to rain.
• 快到了。 = We're almost there.
• 我快累死了。 = I'm about to die of exhaustion. (strong casual expression)

So:

• 手机快没电了 = The phone is about to die / The phone is almost out of battery

Both are possible, but 没电 is the common everyday way to say out of battery / no power.

• 没电 is a fixed, very natural expression
• 没有电 is understandable, but less idiomatic in casual speech for devices

Common examples:

• 手机没电了。 = My phone died / is out of battery.
• 电脑没电了。 = The computer ran out of battery.
• 停电了。 = The power went out. (for electricity in a building/area)

So learners should remember 没电 as a set phrase.

It involves both.

First clause:

• 我的充电器可能放在公司了
• This suggests a past action/result: the charger was left at work, and that is the current situation now.

Second clause:

• 手机快没电了
• This is about the present situation: the phone is now close to running out of battery.

So the whole sentence connects a past event with a current problem:

• the charger is probably at work
• and the phone is about to die now

Yes. A very common alternative is:

• 我的充电器可能忘在公司了，手机快没电了。

Here, 忘在公司了 means left at the office by forgetting it there, which is often exactly what English speakers mean by I left my charger at work.

Other possible versions:

• 我充电器可能落在公司了，手机快没电了。
• 我的充电器可能落在公司了。

Depending on region and context:

• 忘在 emphasizes forgetting
• 落在 often means accidentally leaving something behind
• 放在 is more neutral: it ended up there / was left there

The original sentence is understandable and natural enough, but 忘在公司了 may sound more precise if the meaning is specifically I forgot it at work.

Yes, you can.

• 我的充电器可能在公司。 = My charger might be at the office.

This version focuses only on location.

The original:

• 我的充电器可能放在公司了。

adds a stronger sense that it was left there.

So the difference is:

• 可能在公司 = it might be at the office
• 可能放在公司了 = I may have left it at the office / it may have been left there

Both are useful; the second gives a bit more context.

The sentence follows a very common Mandarin structure:

subject + possessive noun + modal word + verb + location + 了, subject + 快 + state/change + 了

Breaking it down:

• 我 的 充电器 = my charger
• 可能 = possibly / maybe
• 放 在 公司 = left at the office
• 了 = new situation / completed relevant situation
• 手机 = phone
• 快 = almost / about to
• 没电 = have no battery
• 了 = change of state

A smoother structural gloss would be:

My charger + possibly + was left at the office + and now my phone is about to run out of battery.

This is a good example of how Mandarin often puts time, mood, and status markers around the verb phrase rather than using tense the way English does.
