The Anker Prime 9.6K Fusion makes the most sense as a travel-kit simplifier: one block can be your 65W USB-C wall charger and your backup battery. I use one myself, and for my laptop + phone setup, one unit is enough — the bigger benefit is that I no longer have to remember to recharge a separate power bank.
Pros and cons
Pros
- Replaces a separate 65W wall charger and small power bank for many trips
- Two USB-C ports
- Up to 65W from either port when used alone
- Built-in AC plug
- Useful display for remaining battery and live charging or output status
Cons
- Modest 9,600mAh rated capacity
- At 305 g, dense for its capacity
- Two-port output is shared at 45W + 20W
- No USB-A port
Why I keep carrying it
I personally own and regularly use one A1339. One unit is more than enough for my normal laptop + phone setup, and for travel it generally replaces a separate charger and power bank.
I used to forget to recharge ordinary power banks. With the A1339, using it as my wall charger also tends to keep or recharge the bank when the connected-device load permits. It feels a little like a mobile-UPS workflow, but it is not a UPS. Anker notes that a high connected-device load may temporarily halt self-recharging so the attached device gets priority. Anker FAQ
The display is genuinely useful: I can see remaining battery and live charging or output status instead of guessing.
I also bought a second A1339 as a gift for a friend, who found it useful too; that is one anecdote, not independent evidence.
The 65W number needs context
Either USB-C port can provide up to 65W when used alone, in charger mode or battery mode. Connect two devices and the total remains 65W, split 45W + 20W. Anker specifications Anker Support
That split is sensible for a laptop and phone, but it is not full-speed 65W charging for two demanding devices at once.
9,600mAh is backup power, not all-day laptop power
The rated capacity is 9,600mAh across three 3,200mAh cells. Anker estimates roughly 5,200–6,700mAh is delivered after conversion losses. Anker capacity explanation
That is useful backup power for a phone or a laptop top-up, not the same job as a large all-day laptop battery pack.

What independent evidence adds
Mobile01 measured one regional A1339 unit taking about 1 hour 48 minutes to recharge over USB-C and about 1 hour 55 minutes from AC. In that same one-unit test, pass-through or self-recharging slowed under heat and load. These observations describe that unit and test setup, not every A1339. Mobile01 test
Best Buy owner feedback is useful only as a qualitative signal: convenience and charging speed are commonly praised, while some owners call the block dense or heavy. Some reviews are incentivized, and the retailer summary may be AI-generated, so this is not independent measurement or ratings-as-proof. Best Buy owner feedback
Who should buy it
- Travelers who want fewer separate pieces in the bag
- Phone and tablet users who sometimes need laptop-class USB-C output
- People who forget to recharge a separate power bank
Who should skip it
- Anyone prioritizing the most mAh per dollar or per ounce
- People who frequently charge two high-power devices at once
- Anyone who requires USB-A
Bottom line
The special value is reduced charging friction, not merely the 65W output or 9,600mAh rating. For my laptop + phone setup, one unit is enough, and it generally replaces both a separate wall charger and backup battery.
