The Belkin UltraCharge Pro 10K is a 10,000mAh power bank with three ports, 60W of USB-C Power Delivery and a screen on the front that reports battery level, output and temperature. Like its smaller sibling it runs Belkin's BoostSolid semi-solid-state cell, which adds a gel-like layer alongside the liquid electrolyte rather than replacing it. There are no magnets on this one. It costs £69.99 in Black or Sand, weighs 440g, and measures 109 x 73 x 15mm. Every figure here comes from Belkin's press release of 3 September 2026, from Belkin's own UK product page, or from Belkin's Amazon UK listing. All of it was read on 14 September 2026.

The Belkin UltraCharge Pro 10K carries two USB-C ports and one USB-A. First, a single USB-C port will deliver up to 60W. That is enough to charge a MacBook Air or an iPad Pro at a sensible rate rather than a token one. Share the load across ports, though, and the total falls. Belkin's press release says up to 27W shared, while its Amazon listing says up to 30W. Either way, three devices at once means slow charging for all three.
Input is 40W over USB-C, so the pack refills quickly if you have a charger that can push that. Meanwhile pass-through charging runs at up to 15W, which lets the bank charge a phone while it is charging itself. The USB-A port tops out at 22.5W. Typically that one is there for older cables rather than for speed.
On protocols, Belkin lists PD, PPS, AVS and UFCS. Together those cover Apple, most Android fast-charging and the newer Chinese standards. So the pack negotiates the right voltage rather than defaulting to the lowest common denominator.
Belkin's headline claim is an iPhone 17 Pro from flat to 50% in approximately 24 minutes. In addition, the pack itself refills in as little as two hours. Both carry a footnote reading "based on internal testing". Belkin's own UK disclaimer repeats the 24-minute figure and attaches the same condition.
Belkin's Amazon UK listing, meanwhile, says 20 minutes to 50% and 1.5 hours to refill the pack. Yet those are different numbers for the same product, published by the same company, in the same week. So far nobody outside Belkin has measured either.
A small screen sits on the front face. It shows the remaining battery as a percentage, the current power output, and thermal information. Belkin also publishes a separate support article explaining how to read it, which suggests the screen carries more than one state.
A percentage matters more on a 10,000mAh pack than on a 5,000mAh one. With a small pack you charge it whenever you remember. With a bigger one, by contrast, you are working out whether what is left will get a laptop through an afternoon. Four LEDs cannot answer that. So the screen is a genuine reason to pick this over a cheaper 10K.
This is the trade against the UltraCharge Pro 5K. That one is Qi2-certified, snaps onto the back of a phone and charges without a cable. The 10K, by contrast, has no magnets and no wireless charging at all. Instead everything goes through a port.
It is also a bigger object in every dimension. For instance, Belkin's UK spec table gives 109 x 73 x 15mm, while Amazon lists it at 440g. So it is nearly twice the thickness of the 5K and well over twice the weight. That is a bag item rather than a pocket item, and pretending otherwise would be silly.
Belkin says the design is 27% smaller than the alternative, although its two sources define the alternative differently. The UK product page says "27% smaller than standard 10K power banks". The press release footnote, however, is narrower. There the comparison is "with a standard 45W power bank under similar 10K capacity conditions". A 45W pack is a specific class of thing, not the market.
Belkin says the UltraCharge Pro range lasts "up to 3x longer than other power banks". The footnote then defines what that means. The cell retains up to 80% of its capacity after 1,000 charge cycles. And the estimated five-year lifespan "assumes one full charge/discharge cycle every two days".
That second half is doing a lot of work. Specifically, five years only arrives if you flatten and refill this pack 182 times a year. Nevertheless the underlying cycle rating is a real engineering claim, and 80% after 1,000 cycles is a good number for a lithium cell. It is the five-year headline that describes a user who does not exist.
On safety, Belkin says the architecture reduces the risk of thermal runaway, fire and swelling. Dual analog and digital temperature sensors also monitor the cell and cut power if it goes outside its limits. Here too the sources disagree on the interval: the press release says every 250 milliseconds, while Belkin's product page and its Amazon listing both say every 20 milliseconds.
The operating range splits as well. First, the press release gives 0 to 40C. Then the Amazon listing claims stable charging from -10C to 60C. That is a considerably bolder statement, and it is the one we would not repeat without a second source agreeing with it.
The housing is metal, and Belkin says the plastic parts, excluding the cable, are at least 75% post-consumer recycled. A 0.6m braided USB-C to USB-C cable comes in the box. Belkin gives a two-year warranty on the pack itself. Alongside that sits a £1,500 Connected Equipment Warranty, covering a device damaged by an electrical fault while properly connected to it. Finally, the packaging is plastic-free, and the pack is designed to meet UL2056:2025 requirements and TSA carry-on guidance.

Belkin sells it directly at belkin.com/uk in both colours at £69.99. Indeed, both were showing Add to Cart rather than a pre-order button when this page was checked. Amazon, by contrast, is still taking pre-orders. Amazon UK lists the same two colours at the same price, with a release date of 16 September 2026. So an Amazon order placed before that date is a pre-order rather than a dispatch.
For reference, the Amazon ASINs are B0HFJLHJR4 for Black and B0HFJQMXZK for Sand. Both were £69.99 when this page was checked.

Currently it is £69.99 in Black and £69.99 in Sand, on belkin.com/uk and on Amazon UK alike. Belkin, however, ships direct now. Amazon's release date is 16 September 2026, so orders placed there before then are pre-orders.
Neither. There are no magnets and no wireless charging on this model at all. Instead everything goes through the two USB-C ports or the USB-A. For magnetic charging you want the UltraCharge Pro 5K, which is Qi2-certified at 15W.
It will charge many of them, though not all at full speed. For example, 60W is enough for a MacBook Air, an iPad Pro or a Windows ultrabook. Larger laptops ask for 90W or more. In that case the pack still charges them, just slowly. Remember too that 60W is the single-port figure. Plug in a second device and the shared total drops sharply.
Two full phone charges, roughly, with a little left over. Specifically, Belkin's own disclaimer says the amount delivered to your device is less than the 10,000mAh in the pack, because conversion losses take a share. Meanwhile most current phones hold between 3,500 and 4,700mAh.
No. It is Belkin's own internal testing, and the footnote says so on both the press release and the UK product page. It also names one specific phone, the iPhone 17 Pro, at one specific state of charge. Belkin's Amazon listing then gives 20 minutes for the same test. That alone is a good reason to treat either figure as a best case.
Belkin lists real-time battery status, power output and thermal monitoring. In practice that means a percentage rather than four LEDs, plus the wattage currently going out, plus a temperature state. Belkin also publishes its own support article on reading the display.
Not yet. This page is the reference layer: the prices, the specifications and the places where Belkin's own sources disagree. However, an opinion piece with a Cool Factor score follows once we have used one properly. Until then, our service guides hold the rest of the reference layer.
Prices, stock and release dates move. Everything here was checked on 14 September 2026. The sources were Belkin's press release of 3 September 2026, Belkin's UK product pages for BPB044hqBK and BPB044hqSA, and Belkin's Amazon UK listings B0HFJLHJR4 and B0HFJQMXZK.
