Anker 335 vs 535 car charger
Two chargers with identical port counts and an identical 67W headline, from the same company. The published voltage tables show exactly one meaningful difference, and it only matters to one kind of buyer.
By Sawyer V. · Published · How we research
We have not tested any of this. Everything below is compiled from published manufacturer specifications, and the arithmetic is printed so you can check it. This page carries affiliate links: if you buy through one we earn a commission at no extra cost to you, and it does not change the order of the picks. Full disclosure.
The decision
Buy the 335 unless you charge a laptop in the car. Both are three-port, both total 67 W, both carry ActiveShield 2.0 and an 18-month warranty. The 335 caps each port at 35 W; the 535 will put the full 67 W down one USB-C port at 20 V and 3.35 A. Nothing with a phone battery in it draws more than 35W, so for phones and tablets the two chargers are identical in use and one of them costs less. If you do want laptop-speed charging in the car, the UGREEN 130W publishes 100 W on one port for less than either.

The published tables, side by side
Anker is unusual in this category for publishing complete power-delivery objects rather than a headline wattage, and it is the reason this comparison can be made properly at all.
| Anker 335 | Anker 535 | |
|---|---|---|
| Ports | 2 x USB-C, 1 x USB-A | 2 x USB-C, 1 x USB-A |
| Total output | 67 W | 67 W |

| USB-C voltage table | Not published in full | 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3.35A |
| USB-A maximum | 22.5 W | 22.5 W (5V/3A, 9V/2A, 10V/2.25A, 12V/1.5A) |

What 35 W per port actually covers
Everything you are likely to put in a car, with one exception. Phones cap between roughly 20 W and 45 W and most sit near the bottom of that. Tablets are similar. A Qi2 wireless mount wants a 20 W source. All of that fits inside 35W with room spare.
The exception is a laptop, which wants 45 W to 100 W to charge at a useful rate. At 35W a laptop charges, slowly, and mostly offsets what it is using rather than filling the battery.
The honest recommendation
- Phones and tablets only: the 335, or better, the smaller Anker 323 at $19.99 if two ports is enough. You are not using the third port on most days.
- A laptop, and you want an Anker warranty: the 535.
- A laptop, and you want the fastest charge for the least money: the UGREEN 130W, which publishes 100 W on a single port and includes the E-marked cable, on the USB-C charger page.
The cable will cap you before the charger does
A USB-C cable rated for 60W carries 60W no matter what the charger can supply. Above that a cable needs an E-marker chip to negotiate higher current, and cheap cables do not have one.
So a 535 with the cable that came with your phone is, in practice, not a 67W charger. Neither charger includes a cable, which means buying the 535 without also buying a 100W-rated cable produces exactly the outcome you paid extra to avoid. That is the single most common way people spend the premium and get nothing.
What neither of them publishes
An operating-temperature range. That is a notable gap for a device that lives permanently in a 12V socket in a car that reaches 60 to 70 C inside in summer. ActiveShield 2.0 is described as monitoring temperature and adjusting output, which implies the design anticipates heat — but implication is not a published number, and the transparency axis in the scoring counts it as a blank on both.
Neither publishes a protrusion depth either, which is the specification that decides whether a three-port charger fouls your gear selector. If your socket is somewhere awkward, that is a real reason to buy the two-port charger instead of either of these.
Every pick, with the working
Each entry lists the specifications the maker publishes, the axis scores those specifications produce, and what you give up. Rows that read “Not published” are not omissions on our side: they are things the maker will not commit to in writing, and they cost the product points on the transparency axis.

Our pickThree devices, no arguments
Anker 335 Car Charger (67W)
Two USB-C and one USB-A totaling 67W, with a per-port ceiling of 35W. That per-port number is the whole difference between this and the 535: 35W charges any phone at full speed and charges a laptop slowly. For a car with two phones and a tablet in it, this is the right one and it is the cheaper one.

What it gets right
- Three ports, so the passenger argument ends
- PD and PPS support, which is what Samsung phones need for their fastest charging
- 35W per port is more than any phone can take, so nothing is bottlenecked
- ActiveShield 2.0 thermal management, and an 18-month warranty
Flaws
- 35W per-port ceiling means a laptop charges slowly even though the unit says 67W
- Three ports in one 12V socket is a physically chunky thing in a tight console
- Anker does not publish an operating-temperature range
The working behind the 9.0
- Heat headroom: not scored (weight 22%)
- The maker publishes no operating-temperature ceiling, so this axis is dropped and the other weights are re-normalized.
- Install effort: 10.0 (weight 24%)
- Plugs into a 12V socket or a USB port. Nothing to mount, nothing to route, reversible in a second.
- Price against the ceiling: 9.5 (weight 24%)
- Listed at $29.99 on the compile date. This site's buyer has a practical ceiling around $150 for a single upgrade, so the scale rewards everything under $100 and falls away sharply past $150. The live price is very often different, and that is what the button is for.
- Written commitment: 7.0 (weight 15%)
- 18-month warranty. This is the only promise in the entire listing that a court would read, which is why it is scored and the marketing copy is not.
- Spec transparency: 8.8 (weight 15%)
- 7 of the 8 specifications we went looking for are published by the maker (88%). A blank row is never a guess here: it prints “Not published” and it costs the product points, because a figure nobody will commit to in writing is a figure you cannot check.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled September 4, 2026 from Anker's 335 Car Charger product page.
2Charging a laptop in the car
Anker 535 Car Charger (67W)
Skip this one. If you only ever charge phones, this is the wrong one. Nothing with a phone battery in it can take more than 35W, so the 335 does the identical job for less.
Same three ports and same 67W total as the 335, but one USB-C port will deliver the whole 67W on its own at 20V and 3.35A. That is a real laptop charge rather than a trickle, and it is the only reason to pay more than the 335 costs. If nothing you own draws more than 35W, this is money spent on a number you will never see.
- Ports
- 2 x USB-C, 1 x USB-A
- Total output
- 67 W
- USB-C output
- 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3.35A (67 W max)
- USB-A output
- 5V/3A, 9V/2A, 10V/2.25A, 12V/1.5A (22.5 W max)

- List price

What it gets right
- Full 67W from a single USB-C port at 20V 3.35A, published as an explicit voltage table
- Anker publishes the complete PDO table rather than a headline wattage, which almost nobody does
- Input rated 12V to 24V, so it works in a truck as well as a car
- ActiveShield 2.0 thermal management
Flaws
- Pointless unless something you charge actually draws more than 35W
- The USB-A port tops out at 22.5W, so it is the slow port whichever charger you pick
- Frequently out of stock at Anker directly

Questions people actually ask
What is the difference between the Anker 335 and 535?
The per-port ceiling. Both are three-port and both total 67 W. The 335 caps each port at 35 W; the 535 will deliver the full 67 W from a single USB-C port at 20 V and 3.35 A. Everything else — ports, total, safety system, warranty — is the same.
Will the 335 charge my laptop?
Slowly. At 35 W most laptops roughly offset what they are consuming rather than filling the battery. If charging a laptop in the car matters, you want 65 W or more on a single port.
Is the 535 worth the extra money?
Only for a laptop. For phones and tablets the two are indistinguishable in use, because nothing with a phone battery in it draws more than 35 W. And if it is a laptop you want, the UGREEN 130W publishes 100 W on one port for less than either Anker.
Do I need a special cable?
Above 60 W, yes: the cable needs an E-marker chip. Neither Anker includes one, so buying the 535 without a 100 W-rated cable produces exactly the result you paid extra to avoid.
