MEET THE PRODUCT
Belkin BoostCharge Slim 5K with Qi2, in everyday life.
We used the black BPD011 with its built-in stand nearly every other day for about a month. A full power bank usually took our iPhone 17 from around 3–8% to roughly 45–55%. It was easy to carry and stayed attached while walking, but it is a backup for getting through the day, not a replacement for a larger power bank. Our Galaxy S25 Ultra was more practical to charge by cable because it did not have a magnetic case.
THE DETAILS YOU WILL NOTICE
What it brings to your day.
A little peace of mind on the way home
After one meeting, our phone was down to 3% while we still needed to book a car and check its pickup details. Having the Belkin in a pocket made that journey much less stressful. This is where a small emergency bank earns its place.
A family day out
It takes little room in a pocket or handbag, yet provides enough extra charge to keep a phone useful into the journey home, including for a video on the train. We would take it along for that reassurance rather than expect a full recharge.
Moving around at home
The magnetic attachment let us keep taking calls and move between rooms without staying beside a wall socket or holding a large charging brick.
What the black BPD011 feels like
The packaging was tidy, with a USB-C cable and basic setup instructions inside. The bank feels durable and premium. Its silicone charging face helps it grip the phone; the outer side has a metallic-looking finish. After about a month there is a little ordinary wear, but the stand hinge still feels firm and charging remains reliable.
Carrying it and keeping it attached
The slim shape is easy to forget about in a pocket and does not add the bulk of a large power bank to the phone. It aligned neatly with our iPhone 17 and stayed secure while walking. It sometimes came away when pulled from tight jeans, so check that it is still attached before putting the phone away. The compatible MagSafe-style case made no noticeable difference to the hold.
The charge we actually got
From a full bank, our iPhone 17 usually rose from about 3–8% to around 45–55% before the bank ran out. Magnetic charging took roughly an hour by our estimate, without a controlled timer. The 5,000mAh figure describes the battery inside the Belkin, not an amount that all reaches the phone. This is a helpful emergency top-up, not a promise of a full phone charge.
Cable, heat and other phones
We charged a Galaxy S25 Ultra through USB-C and found the cable noticeably quicker in ordinary use, although we did not record a timed comparison. Magnetic charging made the iPhone warm, but never worryingly hot; USB-C did not produce noticeable heat in our use. Trying to align the bank wirelessly on the Samsung without a magnetic case was unreliable, so we used the cable instead.
The useful extras and small annoyances
Four indicator lights gave a quick sense of how much charge remained. The built-in stand was stable at different angles, though we have not used it heavily. In a brief check, the bank continued to charge the iPhone magnetically while the bank itself was plugged in. We did not test two-device charging. The silicone face attracts dust and lint and needs wiping after time in a pocket.
THE WHOLE PICTURE
The reasons to choose it.
The reasons to pause.
What works in its favour
- Slim and light enough to carry routinely in a pocket or handbag
- Secure magnetic hold on our iPhone 17, including through a compatible case
- Comfortable to keep using the phone while it charges
- Included USB-C cable, stable stand and easy-to-read indicator lights
The compromises
- A full bank provided a useful partial charge, not a full iPhone recharge
- The soft charging surface collects pocket lint and dust
- It occasionally detached when pulled from a tight jeans pocket
- At £49.99, it is expensive if you mainly need charge by cable
