Anker PowerPort III 20W Cube PD Charger – White

The pocketable fast charger every iPhone user should carry. The Anker PowerPort III Cube delivers 20W Power Delivery charging — taking the iPhone 13 series to 50% in just 25 minutes — in a tiny 38g cube with a foldable plug. If you are checking the Anker PowerPort III Cube price in Bangladesh, you are looking at one of the smallest 20W chargers Anker makes.

This page covers the PowerPort III Cube in full: the 20W PD fast charging, the ultra-compact 38g design, PowerIQ 3.0 technology, specifications, and the store’s warranty and delivery terms. Every figure below comes from the product page and Anker’s specifications — nothing is invented.

Everything about the Anker PowerPort III Cube follows from one decision: a fast charger only helps if it is actually with you. The 20W output, the 38g body, the foldable plug and PowerIQ 3.0 are all in service of that idea, and the sections below take each one in turn, so you can judge the charger on the figures above rather than on claims.

20W PD Fast Charging

20W Power Delivery is the sweet spot for iPhone charging. The iPhone 13 series hits 50% in just 25 minutes — even faster than the 27 minutes quoted for iPhone 14 (different battery sizes). That’s up to 3× faster than the old 5W charger.

Output is 5V/3A and 9V/2.22A — the two PD profiles that cover iPhone fast charging. The charger negotiates the right one automatically. No configuration, no switches — just plug in and get fast charging.

In practice, that speed changes how charging fits into a day. A short break with the Anker PowerPort III Cube plugged in can add half a battery instead of a small top-up, which means less time planning around sockets and fewer moments when the phone has to stay behind on charge while you head out.

Ultra-Compact 38g Cube Design

At 32.3 × 31.8 × 33 mm and just 38g, this is a true cube — barely larger than a matchbox. The foldable plug folds flat for pocket or bag carry without snagging.

38g is remarkably light for a 20W charger. You’ll forget it’s in your pocket until you need it. For daily carry, there’s no excuse not to have fast charging with you.

The size also changes where charging can happen. A charger this small sits comfortably on crowded power strips and in tight sockets behind furniture, and the Anker PowerPort III Cube leaves neighbouring sockets free far more often than a wide brick does — a small detail that matters at home, in offices and in hotel rooms alike.

PowerIQ 3.0 Technology

PowerIQ 3.0 intelligently identifies your device and delivers the optimal charging profile. Works with phones, tablets, earbuds, and more — not just iPhones.

Compatibility is broad: iPhone 13/12/11/XS/XR/X series, iPhone SE (2nd gen), iPhone 8/8 Plus. Basically, if it charges via USB-C PD or Apple 2.4A, the Cube handles it.

That automatic negotiation is the part most people never notice, and that is the point. With the Anker PowerPort III Cube there is nothing to set and nothing to check before plugging in: connect the cable, and the charger and the device agree on the right profile between themselves, every time, for every supported device.

Advanced Safety

Temperature control and current regulation protect your device during fast charging. The Cube monitors heat and adjusts output to stay safe — silent, automatic protection.

Input is 100-240V, 0.7A, 50-60Hz — universal voltage for worldwide travel (with plug adapter).

Those protections run in the background for the whole charging session, not just at the start. If conditions change while the Anker PowerPort III Cube is plugged in — a hotter room, a longer session, a heavier load — the regulation keeps adjusting, which is why fast charging with this charger stays a set-and-forget routine.

Who Should Buy the Anker PowerPort III Cube

The Cube is ideal as an everyday carry charger — 38g means you’ll actually bring it. Perfect for iPhone users who want fast charging without bulk. Also great as a travel charger (foldable plug, universal voltage) or second charger for office/bag.

It’s not for laptops (20W too low) or multi-device (single port). For those, look at 45W+ or multi-port chargers.

Think of it as the charger that removes excuses. Because the Anker PowerPort III Cube weighs 38g and folds flat, it can live permanently in the bag or pocket you already carry, so the fast charger is present on the ordinary days — commutes, classes, site visits — and not only on trips you packed for specially.

Anker PowerPort III Cube in a Daily Charging Routine

A typical day with the Anker PowerPort III Cube starts wherever the first low-battery moment appears. Because the charger is already in a pocket or bag, the top-up happens during breakfast, at a desk or between meetings, and 20W Power Delivery turns even a short pause into a useful charge — the iPhone 13 series figure on this page, 50% in 25 minutes, is exactly the kind of window a normal day offers. That is the rhythm the Anker PowerPort III Cube was built for.

By evening, the routine repeats without any planning. The Anker PowerPort III Cube goes back into the same pocket, the foldable plug sits flat so nothing snags, and the 38g weight means carrying it every day costs nothing. Few chargers make that promise as credibly as the Anker PowerPort III Cube, because few chargers are this easy to keep on you. A charger that is always present quietly removes the low-battery calculations that a charger left at home never can.

Carrying the Anker PowerPort III Cube: Pocket, Bag and Desk

The cube shape is doing practical work here. At 32.3 × 31.8 × 33 mm, the Anker PowerPort III Cube has no long body to lever itself out of a socket and no sharp corners to catch on fabric. The foldable plug completes the idea: folded flat, the whole charger presents smooth faces on every side. In a coat or trouser pocket, the Anker PowerPort III Cube is closer to carrying a spare cable than a spare charger.

On a desk, the same compactness keeps the Anker PowerPort III Cube out of the way. It takes one socket, leaves the strip around it usable, and its white finish matches the clean look of the product photos on this page. For a second charger that lives at work, few options ask for less space or attention than this one.

How PowerIQ 3.0 in the Anker PowerPort III Cube Handles Different Devices

PowerIQ 3.0 is the reason one small charger can serve a whole drawer of devices. Plug a supported iPhone into the Anker PowerPort III Cube and it negotiates the fast-charging profile; plug in earbuds or a tablet instead, and it agrees a gentler profile suited to that device. The identification happens automatically at connection, with no modes to select. That is why the Anker PowerPort III Cube can be the household spare as confidently as the personal one.

The Anker PowerPort III Cube is not an iPhone-only charger, even though the compatibility list on this page is iPhone-led — the 13, 12 and 11 series, XS, XR and X, SE (2nd gen) and 8/8 Plus. The page also notes the Anker PowerPort III Cube works with phones, tablets, earbuds and more: if a device charges via USB-C PD or Apple 2.4A, this charger handles it, which makes it an easy charger to share.

Anker PowerPort III Cube as a Travel Charger

Travel is where the specification sheet and the design meet. The input range of 100-240V means the Anker PowerPort III Cube works on mains voltages worldwide with only a plug adapter for the local socket shape, while the foldable plug and 38g weight mean it earns its place in even the lightest packing list.

If you are comparing travel options, browse the Chargers & Adapters category for higher-wattage and multi-port alternatives, and remember the charger pairs with a suitable USB-C cable — the Cables & Adapters range covers those. Travellers who pack light tend to judge every gram, and the Anker PowerPort III Cube asks for almost none. For a single-device iPhone trip, the Anker PowerPort III Cube already covers the essentials: speed, safety and universal voltage in 38g.

What the Anker PowerPort III Cube Does Not Do

Honest limits matter as much as strengths. The Anker PowerPort III Cube has a single USB-C PD port, so it charges one device at a time, and its 20W output is a phone-first figure: it is not a laptop charger, and larger tablets will charge more slowly than they would on a 30W or higher charger, as the questions below explain.

Knowing those limits makes the recommendation clearer, not weaker. If your routine is one phone, charged fast, from a charger that is always with you, the Anker PowerPort III Cube matches it exactly. That single-device focus is the Anker PowerPort III Cube working as designed, not a compromise to apologise for. If your routine is a laptop and two phones at once, this is the wrong tool — and the store would rather say so here than after delivery.

One Charger for Home, Office and Bag

Most people do not have one charging place; they have several, and the charger that stays in one place is never the charger in reach. The usual answer is a second unit by the bed and another at the office, and it usually means two of them are slow spares nobody enjoys using. The 38g weight changes that arithmetic: keeping the Anker PowerPort III Cube in the bag means the fast charger travels with you, and when you get home, the same cube simply takes over there too, because it never really left your side.

There is also a tidiness benefit to a charger this small. It does not drag a heavy body against the wall, it does not block the neighbouring socket for the lamp or the laptop brick, and with the plug folded it stores in a drawer without tangling with cables. It also travels between rooms without ceremony, because unplugging something that weighs 38g and folds flat never feels like packing.

It is the kind of object that quietly earns a permanent place in the routine rather than a temporary one. Small chargers tend to disappear into daily life rather than clutter it, and that is a genuine part of the value here: the best charger is the one that is plugged in, in reach, and fast enough that you never have to think about it at all.

Getting the Most From the Anker PowerPort III Cube

Most of the benefit comes from placement, not technique. Keep the Anker PowerPort III Cube where the day actually happens — the bag you take out, the desk you sit at, the pocket you check for keys — and use the short charging windows the day already contains. Owners tend to find the Anker PowerPort III Cube becomes invisible in the best way: present, plugged in, and never thought about. Twenty watts turns those windows into half-battery top-ups instead of single-digit ones.

The rest is simply trusting the automation. PowerIQ 3.0 negotiates the profile, temperature control and current regulation watch the session, and the Anker PowerPort III Cube gets on with it silently. There are no settings to learn and no habits to change — which, for a 38g cube with a foldable plug, is precisely the design working as intended.
