Навіть якщо павербанк не працює, зарядна станція працює.

Навіть якщо means even if.

• якщо = if
• навіть якщо = even if

So навіть adds extra emphasis: the second clause is true regardless of that condition.

In this sentence, it shows contrast:

• Навіть якщо павербанк не працює, зарядна станція працює.
• The charging station works even if the power bank does not.

The comma separates the subordinate clause from the main clause.

• Навіть якщо павербанк не працює = subordinate clause
• зарядна станція працює = main clause

In Ukrainian, when a clause introduced by якщо comes before the main clause, a comma is normally required.

Ukrainian does not have articles like English a/an and the.

So:

• павербанк can mean a power bank or the power bank
• зарядна станція can mean a charging station or the charging station

The exact meaning depends on context, not on an article.

Працює is the 3rd person singular present tense form of працювати = to work / to function.

It matches a singular subject:

• павербанк працює = the power bank works
• зарядна станція працює = the charging station works

Because both subjects are singular, both clauses use працює.

It can mean both, depending on context.

Ukrainian present tense often covers both:

• works
• is working

So павербанк не працює can mean:

• the power bank does not work
• the power bank is not working

English forces you to choose more clearly; Ukrainian often does not.

It is repeated because each clause has its own predicate, and repeating the verb is the normal, clear way to say it.

• Навіть якщо павербанк не працює, зарядна станція працює.

Ukrainian usually keeps the verb in both clauses here. Leaving it out would sound incomplete or much less natural in standard usage. The repetition also makes the contrast very clear:

• one device does not work
• the other does work

They are both in the nominative case because they are the subjects of their clauses.

• павербанк не працює → павербанк is the subject
• зарядна станція працює → зарядна станція is the subject

This is the basic dictionary form for both words.

This is an adjective + noun combination:

• зарядна = charging
• станція = station

The adjective зарядна agrees with станція in:

• gender: feminine
• number: singular
• case: nominative

That is why it is зарядна станція, not some other form.

Yes. Павербанк is a common loanword in modern Ukrainian, based on English power bank.

It behaves like a normal masculine noun in Ukrainian and can be declined:

• nominative: павербанк
• genitive: павербанка
• dative: павербанку
• instrumental: павербанком

So even though it is borrowed, grammatically it fits into the language quite normally.

Because не is a negative particle, and with verbs it is usually written separately.

So:

• працює = works
• не працює = does not work / is not working

This is the standard pattern with most verbs in Ukrainian.

Yes. Ukrainian word order is fairly flexible.

For example, you could also say:

• Зарядна станція працює, навіть якщо павербанк не працює.

That version puts the main point first. The original sentence starts with the condition, which may sound slightly more natural if you want to frame the contrast first.

So both are possible, but the emphasis changes a little.
