How the two models score across four criteria, each out of 10.
Key takeaways
Six things worth knowing before you pick one.
Quick specs
The paper numbers for both Anker Nano 10K models.
| A1259 (30W) | Our pick A1638 (45W) | |
|---|---|---|
| Capacity | 10,000mAh, 36Wh | 10,000mAh, 36Wh |
| Max output | 30W | 45W Wins |
| iPhone 17 charging | 30W | 40W Wins |
| Weight (lighter wins) | 7.6 oz (215 g) Wins | 8.2 oz (232 g) |
| Thickness (thinner wins) | 1.0 in (26 mm) Wins | 1.4 in (36 mm) |
| Built-in cable | Fixed USB-C | Retractable, 27.6 in (70 cm) Wins |
| Airline status | Within 100Wh carry-on | Within 100Wh carry-on |
Specs confirmed against Anker’s product pages for the A1259 and A1638. Measured figures come from TechRadar’s October 2025 review of the A1638. Lit values win the row. See how we test and score.
Charging performance
The A1638 delivers 45W to a single device through its built-in USB-C cable. Anker confirms up to 40W for the iPhone 17 series and 45W for compatible Samsung devices, while the A1259 peaks at 30W.
TechRadar’s October 2025 review of the A1638 found overall performance good for phones, but noted that thermal throttling can pull output down quickly from the 45W peak. Recharging the bank itself slowed to 19W after about 10 minutes, for a full recharge in roughly two hours. It got a little warm near maximum load but never felt overly hot.
Connect a second device through the USB-A port and total output is shared: 24W on the A1259, 22.5W on the A1638. That covers a phone plus earbuds, but two phones at full speed is not what either model is built for.
No outlet has published a measured conversion-efficiency figure for either model, so we are not quoting one. The estimates below assume about 80% efficiency, the typical figure for this class, and they come out the same for both models.
Design and build
Both models share Anker’s Nano design language: a rounded rectangular body, a soft-touch matte finish and a color LED display. The A1259 measures 4.1 x 2.1 x 1.0 in (104 x 52.3 x 26 mm), the A1638 a shorter but thicker 3.2 x 2.0 x 1.4 in (81 x 50 x 36 mm).
The fixed cable on the A1259 exits the curved short edge and folds flat against the body when not in use. The A1638’s InstaCord cable sits flush in the same edge and pulls out to 27.6 in (70 cm) with firm, smooth resistance.
A USB-A port and the USB-C input sit side by side on the flat short edge of both units. The A1638 adds a rubber cap over its USB-C input, which the A1259 lacks.
Build quality matches Anker’s mid-range standard, with no flex in the chassis on either unit. Anker rates the InstaCord mechanism for 20,000 bends and 20,000 pulls, a higher durability rating than most built-in cables at this price.
Portability and travel use
At 7.6 oz (215 g) and 8.2 oz (232 g), both models are light enough for daily carry without becoming the heaviest thing in a bag. The A1259’s flat profile disappears into a jeans pocket or slim bag sleeve, while the A1638’s thicker body sits better in a jacket or rucksack pocket.
In power-to-weight terms the A1259 returns 46.5 mAh per gram and the A1638 43.1, both typical for the pocket 10K class. The gap is the cost of the retractable mechanism, and it is a fair trade if you will use the cable daily.
Neither model needs a separate cable, which is the point of the design: the lead you need is always attached. The A1638’s rewind keeps it tidy, while the A1259’s folds flat against the body.
First impressions
The Anker Nano Power Bank (10K, 45W), model code A1638, and the Anker Nano Power Bank (10K, 30W), model code A1259, both arrive in Anker’s standard retail box with a short USB-C cable for recharging the bank itself. No wall charger is included, so you need a 30W source to refill either bank in reasonable time.
The A1259 stands out for how flat it is: a 1.0 in (26 mm) profile that sits flush in a palm or jacket pocket. The A1638 is more block-shaped at 1.4 in (36 mm) thick, the cost of fitting the retractable cable mechanism inside the housing.
Both units have a physical button that wakes the LED display: press once to check remaining charge, hold to start output. The A1638 display is light-sensitive and brightens outdoors, where the A1259 screen can need a second look.
Darleene asks
“They look identical to me in the photos. What am I really choosing between?”
Alisdair’s answer: Shape and speed. The A1259 is the flat one: 30W, 7.6 oz (215 g), made to disappear into a pocket. The A1638 is the quick one: 45W and a cable that rewinds itself, in a thicker 8.2 oz (232 g) body.
Speed is the part you notice day to day. If you charge an iPhone 17 or a recent Samsung flagship, the A1638 tops it up at up to 40W or 45W, where the A1259 caps at 30W.
If your phone charges at 30W or less anyway, or the bank lives in a tight pocket, the A1259 is the better buy and the thicker body would buy you nothing.
Estimates from a full 10,000mAh bank at about 80% conversion efficiency. Capacity data: manufacturer specifications. Neither model sustains laptop charging under active load.
Pass-through charging
The A1638 supports pass-through charging. With a device plugged in while the bank itself recharges, it prioritizes the device to about 80%, then redirects power to refill the bank, per Anker’s official documentation.
Anker does not list pass-through for the A1259, so treat that model as charge first, then use. If topping up a device while the bank recharges matters to you, the A1638 is the one to pick.
Both models accept 30W input, so a full recharge from flat takes about 2.5 to 3 hours with a 30W charger, which suits an overnight charge cycle. Anker says the A1259 reaches about 50% in 45 minutes.
Airline carry-on
At about 36Wh, both Nano 10K models sit well inside the 100Wh carry-on limit that applies on UK, EU and US carriers, so there is no separate airline approval step: every power bank under 100Wh is automatically cleared to fly. Banks must travel in your carry-on, never in checked bags.

Full specifications and safety
Anker’s official figures: the A1259 weighs 7.6 oz (215 g) and measures 4.1 x 2.1 x 1.0 in (104 x 52.3 x 26 mm), a flat slab that sits neatly behind a phone. The A1638 weighs 8.2 oz (232 g) at 3.2 x 2.0 x 1.4 in (81 x 50 x 36 mm), shorter but chunkier. Both carry a 10,000mAh cell, about 36Wh.

Safety certifications
Both models meet the relevant safety standards for UK and EU sale, per Anker’s UK product pages: CE marking, FCC certification, RoHS compliance and UN38.3 air-transport battery certification. The A1638 adds ActiveShield 3.0 thermal management.
Neither model appears on Anker’s official recall page, which lists every model covered by Anker’s voluntary power bank recalls; checked September 2026. Anker publishes safety notices there, and both models carry an 18-month warranty. Confirm the certification marks on the unit and packaging when yours arrives.
Anker Nano 10K review scores: how we rated both models
Each overall score is the average of four sub-scores on our current rubric: 7.8 for the A1638, 7.4 for the A1259.
Anker Nano A1638 review: 7.8 out of 10
Our pickPort and cable design is where the A1638 earns its premium, scoring 8.5: the retractable InstaCord is rated for 20,000 bends and 20,000 pulls and carries the full 45W. No fixed-cable rival at this price matches it, including the A1259.
Charging speed scores 8.0. Its 45W output is the fastest available in a 10,000mAh bank with a built-in cable, though TechRadar’s October 2025 review notes that thermal throttling can pull it below that peak.
Carry rating is the A1638’s weakest score at 7.0. At 8.2 oz (232 g) and 1.4 in (36 mm) thick it sits upright rather than flat, the honest cost of the rewind mechanism. Value scores 7.5, because the premium only pays off if you will use the retractable cable daily.
Anker Nano A1259 review: 7.4 out of 10
Value pickValue is the A1259’s best score at 8.0: a built-in cable, a bonus USB-A port and 30W output at lower spend.
Carry is its other strength at 7.5: a flat 7.6 oz (215 g) slab, 1.0 in (26 mm) thick, that disappears into a pocket. Charging speed and the fixed cable both score 7.0, which is where it gives ground to the A1638.
That is how the A1638 edges it, 7.8 to 7.4. Buy the A1638 for speed and cable convenience, the A1259 for a flatter, lighter carry at lower spend, and look elsewhere if you need to power a laptop.
The verdict
The Anker Nano 10K solves a real problem: the cable you need is always attached. Both models deliver their rated speeds in independent testing, and both sit well within the airline carry-on limit.
The A1638 is the stronger buy for fast charging: 45W output, up to 40W for the iPhone 17 series, and the retractable InstaCord cable. The cost is a thicker body and a higher spend over the A1259.
The A1259 is the easy recommendation for everyday carry: flatter, lighter and cheaper, giving up 15W of peak speed most phones will never use. If you fast-charge an iPhone 17 or a premium Samsung daily, pick the A1638; everyone else should save the difference.
Should you buy the Anker Nano 10K?
The honest split.
Buy it if
You charge an iPhone 17 or premium Samsung and want 45W without a separate cable (A1638)
You want a flat, light bank that disappears into a pocket or slim bag (A1259)
You fly regularly and want a bank that clears the 100Wh limit with no sums (either model)
Skip it if
You need laptop charging: neither model sustains a laptop under load
You mainly charge USB-A devices and have no use for 45W
You want a replaceable cable: the built-in lead cannot be swapped if it fails
Which Anker Nano 10K should you buy: 30W vs 45W?
Quick answer: the Anker A1259 vs A1638 choice is an Anker Nano 30W vs 45W decision. Buy the A1638 if you want 45W fast charging and a retractable cable; buy the A1259 if you prioritize a flatter, lighter carry and do not need more than 30W.
The A1638 scores 7.8 and the A1259 7.4, and both are recommended. The right choice depends on how you charge your phone and where you carry the bank.

📖 Read the roundupFrequently asked questions
Straight answers to what buyers search for.
What is the difference between the Anker A1259 and A1638?
Both are 10,000mAh power banks with a built-in USB-C cable. The A1259 delivers 30W from a flat, pocketable 7.6 oz (215 g) body with a fixed cable.
The A1638 delivers 45W from a shorter, thicker 8.2 oz (232 g) body with a retractable InstaCord cable and ActiveShield 3.0 thermal management. It costs more but offers faster charging and greater cable convenience.
How fast does the Anker Nano 10K charge an iPhone 17?
The A1638 charges the iPhone 17 series at up to 40W, per Anker’s official specifications. The A1259 maxes out at 30W for iPhone 17.
Both are far quicker than a standard 5W or 12W charger. Actual charge times depend on battery state and ambient temperature.
Can I take the Anker Nano 10K on a plane?
Yes. At about 36Wh, both the A1259 and A1638 sit well within the 100Wh limit that applies on most carriers in the UK, EU and US.
Always carry power banks in your carry-on, not in checked bags. See our power bank airline guide for a full breakdown by carrier.
Does the Anker Nano 10K support PPS and Samsung Super Fast Charging?
The A1638 does, through its USB-C port and built-in cable only. Anker’s product page says that port supports Samsung Fast Charging 2.0 at up to 45W for Samsung phones, which is the fast mode a Galaxy uses. Anker does not use the term PPS on that page.
The USB-A port on the A1638 does not support it, and Anker lists no Samsung fast-charging mode for the A1259, which tops out at 30W. If you charge a recent Galaxy, the A1638 is the one to buy.
Does the Anker Nano 10K support pass-through charging?
The A1638 does. In pass-through mode it prioritizes the plugged-in device until it reaches about 80%, then redirects power to refill the bank itself, per Anker’s official documentation.
Anker does not list pass-through for the A1259, so treat it as charge first, then use. If charging a device while the bank tops up matters to you, pick the A1638.
How long does the Anker Nano 10K take to fully recharge?
Anker rates both models for 30W input, so a 30W or higher PD charger refills the bank from flat in roughly 2.5 to 3 hours. Anker says the A1259 reaches about 50% in 45 minutes. A slower charger or a low-power laptop port extends that considerably.
Is there an Anker Nano 10K recall?
No. Neither the A1259 nor the A1638 appears on Anker’s official recall page, which lists every model covered by Anker’s voluntary power bank recalls. Checked September 2026.
No action is required for either model.
What are the common problems with the Anker Nano 10K?
The main practical limitation is combined output: total power drops when two devices are connected at once, to 24W on the A1259 and 22.5W on the A1638.
The A1638 runs warm during sustained 45W charging, noted in TechRadar’s October 2025 testing as expected behavior for ActiveShield 3.0. Neither model powers a laptop under active load.
Does the Anker A1638 work with Samsung fast charging?
Yes. The A1638 delivers up to 45W to compatible Samsung devices through its USB-C cable, matching Samsung’s flagship fast-charging specification.
That makes it one of the more capable 10,000mAh options for Samsung users.
How many times can the Anker Nano 10K charge my phone?
From the 10,000mAh cell, expect about 2.4 full charges for an iPhone 17 and about 2.0 for a Galaxy S24, at roughly 80% conversion efficiency. Smaller devices like AirPods Pro 2 stretch to about 13 charges.
How much does the Anker Nano 10K weigh, and what size is it?
The A1259 weighs 7.6 oz (215 g) and measures 4.1 x 2.1 x 1.0 in (104 x 52.3 x 26 mm). The A1638 weighs 8.2 oz (232 g) and measures 3.2 x 2.0 x 1.4 in (81 x 50 x 36 mm).
The A1259 is the longer, flatter of the two; the A1638 trades a thicker body for the retractable cable. Both are flight-safe at about 36Wh.
Which Anker Nano model do I have: A1259, A1387 or A1638?
All three are Nano power banks with a built-in USB-C cable, and the code is printed on the label on the base. A1259 is the Nano 10K (30W) with a fixed cable, and A1638 is the Nano 10K (45W) with the retractable InstaCord cable; those are the two models this review compares.
A1387 is the larger Nano 20K (30W). If that is your model, our best 20,000mAh power banks roundup is the right starting point.
Can the Anker Nano 10K charge a laptop?
For a top-up, yes: the A1638’s 45W USB-C output can refill a compatible laptop while it sleeps or runs light tasks. Neither model will sustain a laptop under load; that is where a higher-wattage bank takes over.
Our best 20,000mAh power banks guide covers the models that do.
Final word
The Anker Nano 10K earns its reputation as a portable charger by keeping the cable attached: whichever model you pick, you always have a lead to hand. Both matched their rated speeds in independent testing, and both are safe to fly with.
Fast chargers and cable minimalists should shortlist the A1638; light packers on a tighter budget should take the A1259. See how we test, or see where both rank in our best power banks 2026 roundup.
