HyperJuice 245W: read the split table, not the badge.
245W is a total shared across four ports, which makes it a desk consolidator and makes one number matter more than the headline: the maximum a single port delivers on its own.
Total watts and port watts are different products
Two chargers can both say 245W and behave differently. One offers 140W from its top port — a 28V PD 3.1 contract — while spreading the rest; another caps every port near 100W and reaches the headline only with four devices attached. Only the first fast-charges a 16″ MacBook Pro. So the decisive line is the per-port maximum: a true 240W contract needs the 48V rail, 140W needs 28V. If neither appears on the listing, treat it as a 100W-per-port charger — see 240W USB-C explained.
| Line item | 245W desk class | Read on the listing |
|---|---|---|
| Rated output | 245W total across all ports at once | The single-port maximum, alone |
| Port count | Four, USB-C dominant | Which port is the high-wattage one |
| Protocol | PD 3.1 with EPR rails; PPS on some ports | Whether 28V or 48V is printed; any PPS range |
| Form factor | Desktop GaN brick, detachable AC cord | Whether it hangs or sits on the desk |
| Notable feature | Replaces every charger on a desk from one outlet | The split table for your combination |
Hyper — behind HyperJuice and HyperDrive — sits within the Targus accessories group, so the support path beats a marketplace-only competitor's.
What it's genuinely good at
Desk consolidation, properly. A 16″ laptop, a tablet, a phone and headphones, all live from one outlet — see multi-port and desk charging setups.
Headroom that survives sharing. The reason to buy 245W over 140W is not a faster laptop; it is that the laptop keeps its speed when three other things plug in.
GaN keeps it desk-sized. A 245W linear supply would be furniture. Background on 240W GaN.
Where it falls short
Almost nobody needs 245W. If your largest machine is an ultrabook, a 65W or 100W multi-port unit does the job for far less. Buying 245W to charge a phone faster buys nothing.
It is not portable. A detachable AC cord means two objects in a bag, and a poor travel charger next to a 65W GaN brick.
Cables become the constraint. Every port above 100W needs an EPR-rated 5A e-marked cable — possibly several you do not own; read the e-marked cable guide.
The split table is not optional reading. The high-wattage port is a designated one, so the wrong port quietly halves your laptop's charge rate.
Device fit
Built for: MacBook Pro 16″ at fast-charge speed on the designated port, plus a MacBook Air or iPad Pro, a phone and earbuds — none trickling. Margin to spare: MacBook Pro 14″ at 96W-class, gaming laptops on USB-C, Steam Deck at 45W, Switch dock at 39W, Galaxy and iPhone at their peaks. Adds nothing: phone-only setups — a phone requests 20–27W whether the adapter is 20W or 245W.

Buy it, or buy around it
Buy it if a 16″ laptop shares a desk with two or three other hungry devices; buy 100W or 140W otherwise. See the 240W page, best desk chargers, the cheaper sibling in our CukTech 140W review, and the reviews hub.
FAQ
Can one port deliver the full 245W?
Almost certainly not. 245W is a shared total; the single-port maximum is separate, usually 100W or 140W. Only a 48V port reaches 240W.
Do I need special cables for a 245W charger?
Above 100W, yes — an e-marked cable rated for extended power range. Below that, a standard 5A cable.
Is a 245W charger overkill for a MacBook Pro?
For the laptop alone, yes — 140W fast-charges even the 16-inch model. You go higher so it holds that speed while three other devices draw.
Will it charge my phone safely?
Yes. Power Delivery devices negotiate their own contract, so a phone draws its usual 20 to 27 watts whatever the adapter.
