VONUV 10,000mAh Magnetic Wireless Power Bank Drops to $15.79 on Amazon (US, Canada, UK)

A magnetic wireless power bank from VONUV just showed up on Slickdeals with a 60% discount, and the final price is low enough that it's worth breaking down properly — specs, real complaints from buyers, and where this deal actually makes financial sense.

The Price Breakdown

The listing starts at $39.50. Clip the coupon on the product page and it falls to $13.83, then a checkout promo code (18N2EGO4) takes it to a final $15.79 with free shipping. A few things to know before you get excited about that number:

• You need to be logged into Amazon to clip the coupon and apply the code — it won't show the discount otherwise.
• Coupons and promo codes on Amazon can vary by account, and sometimes need to be reapplied to actually stick.
• This pricing and the free shipping are tied to Amazon.com (US). If you're shopping from Amazon.ca or Amazon.co.uk, check the listing on your local marketplace directly — pricing, coupon availability, and the promo code won't necessarily carry over.

What You're Actually Getting

• 10,000mAh capacity — enough for roughly two full charges on an iPhone 16.
• Magnetic wireless charging built for the MagSafe-style magnet ring on iPhone 12 through 16 (Plus, Pro, Pro Max, and mini variants included).
• 22.5W PD fast charging over USB-C with a built-in cable, no separate cord needed. VONUV's numbers claim an iPhone 16 hits 60% in 30 minutes this way — about 3x a standard charger.
• 9-layer protection chip covering over-voltage, over-current, temperature, and short-circuit scenarios.
• Broader compatibility beyond iPhone: older iPhones down to the 7 and XR/XS Max, Samsung Galaxy S22–S24, A-series and Z-series folds/flips, Pixel phones, and most Android devices via the built-in ports.
• Comes in white or black.

What Buyers Are Actually Saying

Worth reading past the headline discount. On the deal thread, feedback is mixed. Some buyers who picked this up earlier in the year report no issues after months of regular use, including one who specifically hadn't noticed faster drain than other power banks that size. Others are less convinced — a handful of the lower-starred reviews on the product listing flag the battery emptying faster than expected, and at least one buyer on the thread couldn't get the deal to price out correctly at checkout and only saw the smaller coupon discount apply. There's also a recurring comment thread of people questioning whether they trust a lesser-known brand magnetically stuck to an expensive phone — a fair concern with any off-brand magnetic charger, not just this one.

None of this means skip it — a $16 power bank isn't held to the same bar as a $50 one — but it's worth setting expectations before you buy: treat the "2 full charges" and "30 minutes to 60%" figures as best-case, not guaranteed, numbers.

Where This Deal Actually Pays Off

This is a US Amazon listing, and that matters more than usual for a $16 item — shipping and import costs can wipe out the discount entirely if you're ordering into a market Amazon doesn't serve directly.

• United States: the full deal applies as listed — free shipping with Prime (or on $35+ orders), no customs, no conversion loss. This is the market the $15.79 price is built for.
• Canada: Amazon.ca carries similar magnetic power banks and often mirrors US deals within a few days, though pricing and the specific promo code here are US-only. Worth checking Amazon.ca directly rather than assuming this exact code works there.
• UK: Amazon.co.uk buyers should expect a separate GBP listing and price point — VAT is already baked into UK Amazon pricing, so there's no surprise customs bill the way there would be importing from the US directly.
• Anywhere without a local Amazon marketplace or reliable low-cost shipping: this is one to skip, or at least price out shipping first. On a $16 item, even a modest forwarding or international shipping fee can turn a good deal into an average one fast.
