Most power banks that claim to charge laptops are only half-telling the truth. Push 18W or 30W through a USB-C port and the laptop barely keeps pace with its own drain. That is not fast-charging, that is treading water. The Anker A1383 is one of the few carry-on banks that closes that gap. At 65W single-port output it genuinely recovers a MacBook or XPS, not just maintains them. Heavy at around 440g and no pass-through charging. For a laptop travel bank at this price, it earns its place.
For this Anker 87W power bank review, Alan ran the A1383 through a full travel day at Heathrow Terminal 5, charging a laptop and phone simultaneously from a single bank. Output figures and recharge times are cross-referenced against independent lab testing by Charge-Test. For the full methodology, see how we test.
First impressions
Familiar Anker form factor: matte black, four LED dots on the side panel, and a USB-C cable tucked into a recessed slot at one end. The cable has some stiffness to it, which is useful when you are plugging into a laptop on a plane tray table or hotel desk. Pick it up and the 440g registers straight away. This is not a pocket carry, and it does not pretend to be.
In the box: the bank, a USB-C cable, and documentation. No wall charger included. The port layout in the next section explains where the build attention went.
Design and build
The Anker 87W power bank is compact for its capacity class. At 157.5 x 73.7 x 25.4mm it lays flat in the main compartment of a travel organiser without dominating it. Three ports on one face: built-in cable recessed on the left, USB-C in the centre, USB-A on the right. The USB-C port handles input and output, so you can recharge the bank and run a connected device from the same socket when the built-in cable is free.
Four LED dots give a clear read on remaining charge. At 25% per dot, that is precise enough to decide whether to top up before boarding.
Anker rates the cable for 10,000 bends and 5,000 twists. I have not put that to the test yet. Short-term handling shows reinforced joints at the root, which is the typical failure point on integrated cables. That is a claim worth revisiting after months of regular use, not first impressions.
The design holds up on inspection. The charging numbers are where the A1383 has to justify the weight.
Anker 87W Power Bank: charging performance
At approximately 72Wh rated capacity with a typical 15% USB-C transfer loss, you get around 61.2Wh of usable output. That is a calculated estimate, not a stopwatch test.
| Device | Battery (approx) | Full charges |
|---|---|---|
| iPhone 16 | 13Wh | ~4.7 |
| Samsung Galaxy S24 Ultra | 19Wh | ~3.2 |
| iPad Pro 11-inch | 31Wh | ~2.0 |
Calculated estimates based on manufacturer specs and typical USB-C transfer losses. Real-world charge counts vary with cable quality, ambient temperature, and device condition.
Recharge time: 72Wh at 65W input gives a theoretical minimum of around 66 minutes. Independent testing by Charge-Test measured full recharge at 1 hour 38 minutes with a 65W source. Anker’s own figure is approximately 1.5 hours, which is close. To hit that window you need a 65W-capable USB-C wall charger. Pairing the A1383 with a best GaN travel charger makes full use of the 65W input and keeps recharge close to the 90-minute mark.
Running both USB-C outputs simultaneously reduces per-port wattage below the 65W peak, confirmed by independent testing by Charge-Test. You still get useful wattage on both, but not full speed to each device.
The A1383 also supports PPS (Programmable Power Supply) on both USB-C outputs. PPS lets compatible phones negotiate the exact voltage they need rather than accepting a fixed output. In practice that means faster and more efficient charging on Samsung Galaxy models and other PPS-compatible devices. Confirmed by independent testing by Charge-Test.
At a Heathrow Terminal 5 gate, I ran both a laptop and a phone from this bank at the same time. The phone went from low to full in around 90 minutes. The laptop went from 15% to roughly 75% in the same session. That is exactly the use case this bank is built for.
That output comes with a weight penalty that matters for travel. The next section settles the carry question.
Portability and airline travel
At around 440g the A1383 is bag-carry only. It does not fit in a jeans pocket. At 157.5 x 73.7 x 25.4mm it lays flat in the back pocket of most travel backpacks and sits cleanly in a tech organiser alongside cables and a charger.
For air travel, the A1383 comes in at approximately 72Wh, well under the 100Wh carry-on threshold used by most carriers for spare lithium batteries. The Amazon listing confirms airline approval. For a full breakdown of what the rules actually allow, see can you take a power bank on a plane?. Quantity and in-flight use policies vary by carrier, so check your airline before you travel.
Pack it in hand luggage only. Lithium batteries are not permitted in checked bags.

Why we rated it 7.4/10
Charging Speed: 7.5/10 (30% weight). 65W single-port output handles genuine laptop fast-charging. Independent testing by Charge-Test confirmed recharge in 1 hour 38 minutes at 65W input, closely matching Anker’s 1.5-hour claim. PPS is confirmed on both USB-C outputs. No pass-through and 100W rivals at a similar price cap the ceiling.
Carry Rating: 7.0/10 (25% weight). Around 440g is the expected weight for a 20K/65W bank. Bag-carry, not pocket carry. Airline compliance at approximately 72Wh is a genuine plus. The built-in cable trims overall kit weight slightly.
Value for Money: 7.5/10 (25% weight). 4.5 out of 5 from over 7,000 Amazon ratings signals broad buyer satisfaction. The INIU 25K offers more capacity and output at a similar price, which limits the value ceiling. Anker brand reliability and built-in cable convenience partially offset that.
Cable Design: 7.5/10 (20% weight). The built-in cable delivers the full 65W, identical to the USB-C port. Anker rates it for 10,000 bends and 5,000 twists. Not retractable and not replaceable if damaged. The recessed housing design is practical for travel.
The Anker A1383 scores 7.4 because it delivers genuine laptop-speed charging at 65W, includes a built-in cable running at the same output as the port, and sits comfortably under the 100Wh carry-on threshold. It concedes on weight (around 440g) and lacks pass-through charging. For a 20K laptop bank at this price, the package is harder to match than the headline wattage suggests.

Anker 87W Power Bank FAQs
-
Is the Anker A1383 allowed on planes?
Yes, it is typically within carry-on limits. At approximately 72Wh, the A1383 sits well under the 100Wh threshold used by most carriers for spare lithium batteries. It must travel in hand luggage, not checked bags. Individual airlines apply different quantity and in-flight use restrictions, so it is worth checking your carrier’s own policy before you travel.
-
Can the Anker A1383 charge a laptop properly?
Yes. At 65W from either the USB-C port or the built-in cable, the A1383 delivers genuine laptop-speed charging. Most USB-C laptops, including current MacBooks and XPS models, will accept 65W input and charge at a useful rate. You are not getting a slow trickle or a maintenance charge; you are getting a real fast-charge session.
-
How many phone charges do you really get from the Anker A1383?
Based on approximately 72Wh rated capacity with a 15% transfer loss applied, you get around 4.7 full charges of an iPhone 16 or about 3.2 full charges of a Samsung Galaxy S24 Ultra. These are calculated estimates. Your real-world results will sit close to these figures depending on cable quality, ambient temperature, and device battery condition.
-
How long does the Anker A1383 take to fully recharge?
With a 65W charger, around 1 hour 38 minutes based on independent testing by Charge-Test. Anker’s own figure is approximately 1.5 hours with a 65W input. Both are consistent. You need a 65W-capable USB-C charger to hit that window; a slower charger extends the recharge time considerably and is worth factoring into your travel kit.
-
Does the built-in USB-C cable charge as fast as the USB-C port?
Yes. Both deliver up to 65W, so you are not trading output speed for cable convenience. The practical limitation is length: the integrated cable is shorter than a standard cable. For desk use with your phone held in hand the shorter reach can feel limiting, but for laptop-on-desk or bag-to-device use it works without issue.
