CHOETECH B743 Magnetic Power Bank: Wired or Wireless Charging?
By Modexa
Understand the B743's listed charging outputs, magnetic fit and 10,000 mAh capacity before choosing a power bank for your phone.
Choose around how you use your phone
A power bank can be useful when your phone spends the day away from a socket. The CHOETECH B743 listings at Modexa offer a magnetic design with a holder in black or white. Before choosing, think about your usual charging situation: keeping a cable in a work bag, topping up while seated, or carrying the phone with an accessory attached. This guide explains the listed features and the questions to check before ordering; it is not a hands-on charging test.
Separate the wired and wireless figures
The B743 specifications list USB-C output up to 20 W and wireless output up to 15 W. These are different connection methods with different stated maximums. A PD20W label does not mean every phone receives 20 W wirelessly. Check your phone's supported charging method and the accessory's compatibility with that exact model. Use the listing's figures as limits to compare, rather than a promise of the speed you will see in every situation.
Check the phone and case together
A magnetic accessory needs a suitable attachment surface as well as charging compatibility. Confirm that the B743 supports your phone and the case you actually use. A case that fits the phone does not automatically establish that a magnetic charger will attach or align correctly. Check for camera-bump clearance and ask about your combination if the product page does not name it. Remove a wallet or other accessory occupying the same attachment area before setting up charging.
Treat 10,000 mAh as a capacity specification
Both colour listings name a 10,000 mAh capacity. That figure alone does not establish an exact number of complete phone recharges. Usable charging results depend on the devices and conditions, so avoid choosing by a simple capacity-to-phone-battery division. If you need a particular amount of backup power, look for documented results for your phone or ask for more information. Plan access to a charger rather than relying on an unverified full-day runtime claim.
Consider the size as well as the holder
The listed dimensions are 101.5 by 72 by 21 mm, with a listed net weight of 211 g. Compare those measurements with your phone and how you carry it. A holder may be convenient at a desk, but consider whether you prefer to detach the bank for calls or storage. Check the supplied instructions for the holder's intended use and placement. Product photos can help you understand the shape, but measurements are the better guide to bulk.
Plan how you will recharge the bank
The specifications identify a USB-C input and list input ratings of 5 V/2 A and 9 V/2 A. Before ordering, confirm which cable and wall adapter are included and which you need to supply. Do not assume the bank comes with everything pictured in a lifestyle image. Review the current product page for available options, price and delivery details. Black and white have separate listings, so confirm the colour and selected item in your cart before checkout.
