Review of the Ravpower 7.5 W wireless charger for iPhone X and iPhone 8

In the
series of iPhone accessories, this year should be that of equipment in
wireless charger, for those who have an iPhone 8 or
want to add a Qi charging accessory to their iPhone plus
ancien.

We saw
in this file and in video what are the different types of charger
wireless and how they work.

We also tested
the standard 5W model from Choetech, the
BoostUP the Belkin and 7.5 Wand today, it's a second charger called
“fast”, capable of delivering the maximum 7.5 W that the iPhone X accepts
and 8. It is offered by the brandRavPowerat a rather low price
reasonable compared to its competitors.

7.5 W is on sale here

Premier contact

Delivered in a small cardboard package, the RavPower Qi charger
comes in the form of a disk of relatively compact size, and very
dense. We feel a significant, but reassuring weight in the hand.

On the top, a circle of adhesive material is provided to retain the
smartphone (important for vibrating calls which can drop the
machine).

Feet also in grippy rubber are also provided on the
below:

The base comes with a powerful USB charger, as well as a plug-in cable
woven micro-USB, of good quality a priori.

Getting started and charging time

Getting started is easy, just plug the USB charger into a
socket, then the cable to the transformer and to the base.

When the iPhone is placed on the base, a red LED signals charging in
course.

As for the power, as we have seen, the charger is 7.5 W,
specially designed for iPhone X and 8.

This gives the following performance, starting from an iPhone at 1% of
charge :

after 30 min: 22%
after 1 hour: 37%
after 1h30: 55%
after 2 hours: 70%
after 2.5 hours: 85%
after 3 hours: 98%

Here are also the times recorded with a5W Qi charger
standard, also starting from a machine around 1%:

after 1 hour: 35%
after 1h30: 50%
after 2h30: 75%
after 3:30 a.m.: 100%

To compare the duration and charging speed with the competitor's
Belkin, the BoostUP, here is
the times recorded starting from approximately 1% residual load
on aiPhone X:

after 1 hour: 41%
after 1h30: 58%
after 2 hours: 78%
after 2.5 hours: 88%
after 3 hours: approximately 100%

The weight and the small feet under the base allow a good hold on a
bedside while the machine is well held thanks to the ring in
“eraser” used on top. On the other hand, this eraser
naturally tends to retain dust, a regular wipe
is to be expected for the most demanding on the subject.

Light and noise

We note that the choice of a red light, not classic (we often see
blue or green) can be a little aggressive if used in a bedroom
(but good tastes and colors) especially since the LED continues to work
even when the machine is fully loaded.

The instructions can also be misleading by indicating passages to
different colors including green, but this corresponds to use with
an Android machine. For the iPhone, a single LED that pulses gently
when the machine is well positioned is used, because the iPhone does not send
not sufficient information at the base for the color change to be
managed.

As for this indicator light, given the size of the base, the iPhone
can be placed in such a way as to hide it, but it remains a red light which
diffuse. On the question of noise, some mention a whistling sound
charger level when the iPhone is not charging. This is not
not the case of our model, this means that you should not
keep a charger that whistles, this is abnormal, and ask for a change.
Complete silence for the model tested, whether it is charging or not.

Temperature when charging

In terms of temperature, here are the measurements taken:

Surface temperature of the charging base: 37.7 degrees
(compared to approximately 41.5 degrees C on the Boost UP)

And the back of the iPhone barely removed from the base to get an idea of
the temperature reached: 38.9 degrees (compared to 38.8 degrees C for the Boost
Up)

The temperature on the surface of the iPhone (front) placed on the base, in
recharge course: 32.5 degrees (compared to 35.6 degrees C for Boost Up)

For comparison, under similar conditions, the temperature of the iPhone
X charging with the wired USB charger delivered by Apple (5W) displays a
temperature at the hottest point (rear) 28.2 degrees. With a charger
Fast wired USB type iPad charger, the temperature rises to the highest point
hot at 32.4 degrees.

Size compared with Belkin BoostUp

Here are photos of the difference in design and size between the 7.5 W model
from Belkin, in the shape of a large saucer and that of RavPower, more
compact and rounded:

Seen in the comments, but not tested: the reduced size of the base
if it is practical for the discreet and mobile aspect and well suited to an iPhone
X and 8, turns out to be a handicap compared to the size of an iPhone 8 Plus.

Conclusion

This charger which seduces with its compactness, its weight and its density
reassuring. This is also one of the rare Qi chargers that we
would almost take in your suitcase for those who are addicted to wireless charging. He
also allows faster charging than induction chargers
classics, at a price which is higher but not that much since it is
currently theCheapest 7.5W iPhone compatible model on the
walk, In addition, it comes with a fast charger (Quickcharge)
which can be reused with your iPhone and a Lightning cable or for a
Android smartphone. Feedback on whistling, loading stops
sometimes for no reason and an insufficient size for good stability of
the iPhone 8 Plus are also worth noting!

The RavPower Qi charger
7.5 W is on sale hereat a price of around 37 euros.

Also note for those who do not have the iPhone 8 or
possible to offer Qi charging to your older iPhone, we tested three
