What charger do I need for an dell laptop?
Dell uses many charger types across Inspiron, Vostro, Latitude, XPS, G Series, Precision, and Alienware.
The fastest way to pick the correct charger is to match output voltage, wattage, and the connector type
(including Dell’s center pin)—or use your Dell Service Tag to double-check compatibility.
4.5×3.0mm & 7.4×5.0mm (center pin)
USB-C PD on some models
Match voltage, then watts
If you’re unsure, a photo of your old adapter label + your laptop model/Service Tag is the quickest way to confirm the exact match.

1) 60-second checklist to choose the right Dell charger
-
Check your current adapter label (if you have it):
look forOutput(voltage + amps or watts), for example19.5V 3.34A (65W). -
Match the connector type:
Dell commonly uses barrel plugs with a center pin (ID pin) or USB-C PD. -
Confirm laptop model + Service Tag:
the Service Tag is a 7-character code on the bottom sticker. -
Rule of thumb:
keep the same voltage, then choose equal or higher wattage than your original.
If the pin is missing/damaged or the charger is the wrong type, you may see slow charging, “adapter not recognized,” or reduced performance.
2) Read your original Dell adapter label (what matters)
On the adapter sticker, focus on:
- Output voltage and current / wattage (common Dell outputs include 19.5V with different amp/watt ratings).
- Dell adapter part numbers (examples you may see:
LA65NS2-01,DA65NM111,LA90PM111,HA130NM130,DA180PM111,LA240PM180, or450-xxxxcodes). - Older “family names” on some chargers (e.g., PA-series like
PA-12,PA-3E,PA-4E).
| Label item | Example | What it means | How to use it |
|---|---|---|---|
| OUTPUT | 19.5V 3.34A / 65W | The DC power your laptop needs | Voltage must match; wattage should be equal or higher |
| Connector | 4.5×3.0mm (center pin) | Physical fit + adapter recognition | Must match the DC jack size/type |
| Part Number | DA65NM111 / 450-xxxx | Exact model reference | Best keyword for searching the correct replacement |
3) Dell connector types (4.5mm vs 7.4mm vs USB-C PD)
Dell commonly uses these charger connectors:
| Connector type | How to recognize it | Commonly seen on | Important note |
|---|---|---|---|
| 7.4 × 5.0 mm with center pin | Large round barrel + pin inside | Many older Inspiron / Latitude / Precision / Alienware | Pin (ID) is important for recognition |
| 4.5 × 3.0 mm with center pin (blue tip) | Smaller “blue tip” barrel + pin | Many modern Inspiron / Vostro / Latitude / XPS / G Series | Do not confuse with similar-size non-Dell tips |
| USB-C PD (Power Delivery) | Charges via USB-C port | Some newer XPS / Latitude / Precision / G Series | Must be a PD-capable charger with enough wattage |
A basic USB-C cable/charger without proper PD wattage may power on slowly or not charge at all.
4) Wattage rules (what happens if you choose the wrong power)
Common Dell charger wattages include 45W, 65W, 90W, 130W, 180W, 240W, 280W, 330W (and sometimes higher for specific setups).
| If you use… | Likely result | Best practice |
|---|---|---|
| Same voltage + lower wattage | Slow charging, may not charge under load, performance may be limited | Avoid on gaming/workstation models; match original wattage class |
| Same voltage + equal/higher wattage | Normal charging and performance | Recommended (laptop draws only what it needs) |
| Wrong voltage | No charge or potential damage risk | Never “guess” voltage—match the label |
5) Use your Dell Service Tag (best for accuracy)
Turn your Dell laptop over and find the Service Tag (7 characters).
This is the most reliable way to confirm the exact charger for your specific configuration—especially on families like XPS, Precision, and Alienware.
- Also note the model name (example formats: Inspiron 15 3511, Latitude 5400, XPS 13 9310, G15 5520, Precision 5530, Alienware m15).
- If available, read the DC rating printed on the bottom label (sometimes shows “19.5V …A”).
6) Common mistakes that cause “not charging”
- Wrong connector size: 7.4mm and 4.5mm can’t substitute unless you use the correct conversion accessory (and it still may not be ideal for all setups).
- Missing/damaged center pin: the laptop may not recognize the adapter, resulting in slow charging or warnings.
- Underpowered wattage: the laptop may charge only when sleeping/off, or may drain while plugged in during gaming/heavy load.
- USB-C without PD or not enough watts: it may power the laptop lightly but fail to charge the battery.
- DC-in port issues: loose jack, broken port, or motherboard charging circuit can mimic a “bad charger.”
If the message persists, the DC jack/charging port may need inspection.
7) What to search on our website
To find a compatible Dell charger quickly, search using one (or more) of the following:
- Original Dell adapter part number (e.g.,
LA65NS2-01,DA65NM111,LA90PM111,HA130NM130,DA180PM111,LA240PM180,450-xxxx). - Voltage + amps/watts + connector (example:
Dell 19.5V 3.34A 65W 4.5×3.0mmorDell 19.5V 4.62A 90W 7.4×5.0mm). - Full laptop model (example: “Dell Inspiron 15 3520”, “Dell Latitude 7410”, “Dell XPS 13 9305”, “Dell G15 5511”, etc.).

FAQ
Is 19.5V the same for all Dell laptops?
Many Dell adapters use 19.5V, but not all charging setups are identical—especially USB-C models.
Always match the exact output rating shown on your original adapter label or laptop requirements.
Can I use a higher-wattage Dell charger?
Generally, yes—if the voltage is the same and the connector type matches.
Higher wattage is usually safe because the laptop draws only what it needs.
My Dell uses USB-C. Do I just need any USB-C charger?
Not necessarily. Many Dell USB-C charging laptops require USB-C Power Delivery (PD) and enough watts (often 45W/65W/90W+ depending on the model).
A low-power USB-C phone charger may not be sufficient.
What information should I send to confirm the correct charger?
Send: (1) a clear photo of your old adapter label (Output + part number), and (2) your laptop model + Service Tag from the bottom sticker.
That combination is usually enough to confirm the exact match before ordering.
Still unsure which Dell charger you need?
Match voltage + wattage + connector (center pin), or use your Service Tag for a quick compatibility check.
